Bromeliad: The Most Exotic Houseplant

These fascinating plants are among the most exotic houseplants a gardener can grow and also among the easiest. Not a genus in themselves, but a large group of  genera they include Aechmea, Billbergia, Cryptanthus, Dyckia, Guzmania, Neoregelia, Nidularium, Tillandsia and a number of others. Bromeliads come from the jungles of South America. Some are terrestrial, but many are air plants (epiphytes) living high up in the trees without any soil and taking nourishment only from whatever organic matter washes their way. They are not parasitic and do not draw nourishment from the trees themselves. Tree growing bromeliads catch rainwater in cuplike urns of leaves.

Bromeliads are grown mainly for their spectacular flowers, but the leaves are often particularly handsome too. A typical bromeliad has a rosette of leaves, sometimes soft and green, sometimes stiff and spiky with variegated markings.  A flower stalk usually emerges from the center of the rosette. The showiness of these flowers really lies in the brilliantly colored bracts that surround them, though the tinier flowers are also beautiful. A plant blooms only once, but the flower is often extraordinarily long lasting, and bromeliad plants readily produce offshoots. You may remove these from the mother plant and report them or cut out the spent mother plant and let the cluster of new ones bloom together.

If you are looking for a bromeliad to start with try Aechmea fasciata. You might find itmarketed under various names such as “urn plant” or “silver vase”, but you will recognize it by its vase of stiff, tooth-edged green leaves, marked horizontally with silver bands. The flower spike has toothed bracts of a bright pink color; little blue-purple flowers nestle among pink spikes.

Best of all, this colorful spectacle lasts about six months. The plant grows 1 to 2 feet tall. Another gorgeous long blooming bromeliad is Guzmania  lingulata, which is about the same size, with long green, strap like leaves sometimes striped with purple and a red-orange cluster of bracts enclosing white flowers from late winter or summer. Bromeliads with stiff, variegated leaves like good, bright light and often will take some direct sun but don’t expose them to strong midday sun in summer those with softer, green leaves are fairly shade tolerant.

They do well under artificial lights. They are happiest in warm rooms 65-75 degrees at night even lower from Aechmea fasciata. Give them humid air and a very light, porous organic soil or soilless mix remembers that May bromeliads are air plants and their roots don’t normally grow in soil. Some gardeners grow the ephiphytic types on pieces of tree branch wrapped in moistened sphagnum moss, but a shallow clay pot will do fine.

You can allow the top inch or so of the pot to dry out between watering (overwatering can lead to fungus diseases), but always keep the cup inside the leaves filled with water. Feed lightly a balanced liquid fertilizer at half the suggested strength added to the soil and cup once a month in spring and summer is about right. Propagate by dividing offsets with a knife and repotting them.

The Best Fern’s to Grow Indoor

Ferns “Many Genera” give a better softening effect to an indoor environment that makes good houseplants. Many people are familiar with that old favorite, the Boston fern “Nephrolepsis exaltata ‘Bostoniensis’ ” a very easy indoor plant with rich green, arching fronds; in the variety ‘Fluffy Ruffles’ they are rather upright and have frilled edges. Even more foolproof is its relative, the Dallas fern (N. e. Dallassi) which grows less than a foot tall. Well, there are many species of tropical and subtropical ferns, however, lot of ferns that are native to more temperate climates. These ferns would be well fitting to cooler parts of the house but won’t survive in rooms that are too well heated.

 

Bird’s nest fern (Asplenium nidul) type of spleenwort, has wide, shiny, wavy edge fronds that look more like leaves and they can grow two to three feet tall. Holly fern (Cyrtomium falcatum) also has leaf like fronds a bit like large holly leaves and is extremely adaptable as an indoor plant. If you want something a bit unusual that’s very easy to grow try rabbit’s foot fern (Davallia fejeensis) a beautiful feathery fern from the South Pacific. Its long rhizomes look like brown, furry paws and can be seen crawling out of the pot and hanging from its rim.

When supplying an office with plants once set of these on a woman’s desk, and the fern made her so nervous that she couldn’t sit next to it but most people find D. fejeensis charming. Another exotic that is not terribly hard to grow is the staghorn fern (Platycerium bifurcatum), who’s gray green fronds look like antlers like those of a moose than those of a stag. It is an epiphyte, generally grown on a piece of wood or bark, with its roots wrapped in moistened sphagnum moss.

Few ferns can tolerate much, if any, sun and most grown indoors don’t like deep shade either. Give them bright indirect or filtered sun and an average room temperature. The one thing they are really fussy about is humidity. Generally, the more feathery its fronds, the more moisture in the air a fern needs. Ferns with leaf like fronds are more droughts tolerant. Misting or using a humidity tray may make the difference for you.

Moreover, ferns are shallow rooted and should be grown in shallow pots in a light, organic soil mix. Keep the soil evenly moist but not soggy the phrase “like a squeezed out sponge” is often used to describe the right degree of wetness. The surface can be permitted to dry out between watering in winter. However, water the base of a staghorn fern when it feels dry. Indoor ferns do not need a period of dormancy, though they may go dormant if the temperature is below 50 degree.

Thus, feed your ferns in the summer time every 2-4 weeks with a liquid fertilizer, but don’t mix it full strength because you can damage the root system. Also they can be fed lightly about once a month all year. You can move them outdoors in summer but not into direct sun. Ferns spread by runners, which can be severed and replanted for propagation. To propagate rabbit’s foot fern pin the tip of a “FOOT” to the surface of moist sand with a hairpin. Source: CP

Wonderful Blooming Cactus Flower

The Amorphophallus Titanum

The Amorphophallus Titanum, more commonly famous as the corpse flower, blooming process can take up to 10 years, and the bloom only lasts 24-36 hours. The corpse flower is one of the rarest and largest flowers in the world, not to mention one of the only flowers that emit the smell of rotting flesh. The flower, named "Rosie", is bloom produce small reddish fruit that will take six months to ripen. Amorphophallus titanum, also recognized as the titan arum, is a flowering plant with the largest unbranched inflorescence in the world. The titan arum's inflorescence is not as large as that of the talipot palm, Corypha umbraculifera, but the inflorescence of the talipot palm is branched rather than unbranched. The scent is a deception device that tricks pollinators into thinking the plant is rotting organic matter.

When it blooms, it emits a repulsive odor of rotting flesh, but it's amusing to some insects.  The smell attracts beetles and flies that the plant needs for pollination. Once the fruit ripens, Tucson Botanical Gardens will take the seeds out and sow them to try to grow some smaller Amorphophallus Titanums or share seeds with other botanical gardens. The corpse flower named “Rosie” is located at the Cox Butterfly and Orchid Pavilion exhibit. Amorphophallus titanium, translates as "giant misshapen penis" holds the record for the world's largest unbranched inflorescence (flowering structure).

This mesmerizing species is a tropical rainforest plant can grow in a container. The retail-size plants that we sell are 1-2 yr old seedlings that will grow to about 24 inches tall in their first year. So you should start with a 6" or 8" container. As the tuber gets larger, you should pot it up (be careful not to bruise or nick the tuber during transplanting or else it could rot). Although the flower is naturally found only in Indonesia, since 1889 they have been successfully cultivated in botanical gardens around the world including Kew Gardens in London and the University of Washington, Seattle.

 

How to Grow Philodendron

The name “philodendron” means “tree loving” inspired by the tree climbing habit of many of these South and Central American jungles plants. Some species are not so jungle plants. Philodendron is a large genus of flowering plants in the Araceae family. Some species are not so vining in their habit, however forming new growth at the base, branching and creeping along the ground; these are known as the “self heading” types. Philodendrons may seem like rather mundane pants simply because they are so common because they are so easy to grow. Further, Philodendron houseplants are quite often perplexed with pothos plants. Whereas the leaves of these two plants are alike in shape, pothos plants are more often than not variegated with splotches of yellow or white color. Because, pothos is a much smaller plant as well and is often sold in hanging baskets.

 

Anyone can grow a philodendron. But they can be used in interesting ways cascading from indoors balconies, for instance. And there are many species and cultivars you have probably never heard of but might like to grow once you start to explore them. The most familiar philodendron, a vining plant with smooth, heart-shaped leaves, is sometimes called “heart leaf” and is known by three Latin names; Philodendron scandens, P. oxycardium and P. cordatum. You also might try the vinnin P. bipennifolium, or fiddle-leaved philodendron, which has large, violin shaped leaves when full grown. Usually, however, philodendrons germinate on trees.

 

Like many vining plants it is often grown on a bark-covered support (usually a piece of wood). P. selloum, sadle-leaved philodendron, has deeply lobed leaves and is a self-heading type, as is P. wendlandii, which looks something like a bird’s nest fern. There are also philodendrons, varieties with brightly colored or variegated leaves. If you want to grow philodendrons then give bright light if possible, they will tolerate low light but don’t like strong, direct sun. Philodendrons have both aerial and subterranean roots. Nothing like most houseplants, philodendrons don’t experience as much stress when moving from indoor to outdoor settings.

 

Moreover, average warmth and humidity are fine, though they prefer quite humid air, and the variegated ones like it pretty warm. Keep the soil evenly moist but not too wet, and feed about once a month with a liquid houseplant fertilizer. Feed less in winter, a bit more in spring and summer. They like an average potting soil with organic matter and should be repotted only when very root bound. Pinch straggly, vining specimens if you want them bushier. They are propagated very easily from stem cuttings tip cutting for vining types. 

 

Lilacs in the Spring

Lilac has become one of the most popular of our garden shrubs. The emergence of its sweat smelling blossom in May is a sure sign the summer is just around the corner. Many of the lilacs being grown these days are specially breed varieties that offer a range of flower colors from white, through pink or blue, to deep violet. The original lilacs had pale pinkish violet flowers the color now called lilac.

 

Lilac belongs to that small group of plants that are so familiar in Britain that people mistakenly assume they are native. In fact, most lilac species are native to Asia, with just a few species being found in Eastern Europe. All lilac species are members of the same genus, Syringa, which is itself a member of the olive family. Like other members of this large family, such as privet, ash and forsythia, lilac grows extremely well in the British Isles. One great advantage is that it is tolerant of both acid and alkaline soils. Indeed, on a small scale lilac has become naturalized in this country. The earliest species of lilac to be introduced in Britain and still the one most commonly grown here is the common lilac “Syringa vulgaris”. This species is native to Eastern Europe and Asia Minor. The word lilac comes from the Persian word for bluish lilac or nilak. It was first appeared in Western Europe I the 16th century and was introduced to Britain in 1621 by the naturalist John Tradescant, who later became King Charles I’s gardener.

 

In appearance, the common lilac is typical in many ways of most Syringa species. It is a shrub or occasionally a small tree, growing no higher than 8m. Usually, it it has several stems growing from the base although there may be just a single slim trunk. The bark is smooth and grey. The leaves are mid green, smooth surfaced and have a characteristic heart shape. They are folded along the central vein so that when seen in cross section, they are shaped like a V. The leaves can grow to a length of 15cm.

 

The flowers emerge in May on pyramidal panicles about 15 to 20cm long. On common lilac, the flowers are not surprisingly, lilac colored but on other species of lilac they can vary from white to pink, mauve, blue or deep purple. The panicles may also be much longer on other species, sometimes reaching a length of 45cm. The flowers are followed by the fruits. These consist of flattened capsules that split, each releasing two winged seeds; they ripen in October.

 

Soon after the common lilac reached Britain the first of many lilacs native solely to Asia was discovered. This was the Persian lilac “Syringa laciniata”, named after the country in which western botanists first discovered it growing. In fact, it has been cultivated in both Persia and India for centuries. The Persian lilac in much smaller than the common lilac, rarely reaching more than 2cm in height. It is unusual among lilac in having leaves that are lobed rather like those of an oak. It produces violet purple flowers in May.

 

The Persian and common lilacs were crossed several times in attempts to produce a superior lilac. The most notable success came in 1795, when once Monsieur Varin, the Director of Botanic Garden at Rouen in France, produce a hybrid that was named Rouen lilac “Syringa x chinensis”. This is a handsome shrub, still popular among gardeners. It grows to a height of 4.5cm and bears large compound panicles of lilac colored flowers in May. At this time of the year, the whole bush may be covered with flowers.

 

Moreover, during the 19th century, many more lilac species were discovered and brought back to Britain as botanists began to explore the Far East. The famous plant hunter, Robert Fortune, discovered Syringa oblate growing in a Shanghai garden in 1856. Unluckily it does not flower well in this country because its blossom appears early in the year. Often, a spell of warm weather in early spring induces the flower buds to grow, only for them to be killed soon after by a sudden cold snap.

 

Despite its frequent failure to flower well, S. oblate soon proved itself to be a useful source from which to breed hybrids and varieties. Many of the beautifully colored lilacs grown today are crosses between the common lilac and S. oblate. Much of this work was done by the French horticulturists Victor Lemoine and his son Emile in Nancy during the 1870s’. Several of the far eastern species of lilac resemble small trees rather than shrubs. For example Syringa pekinensis grows to a height of 6m and always has single trunk. In June its spreading branches are covered with a profusion of cream colored flowers borne on small panicles 7 to 12 long. This species was discovered in northern China at the end of the last century.

 

Further, during the 19th century one further species of European lilac was found to place alongside the common lilac. It was discovered in 1830 growing in Transylvania and the Carpathian Mountains of Eastern Europe by the Baroness of Josika. It is now known as the Hungarian lilac “Syringa josikaea”. This lilac is not one of the most attractive but like Syringa oblate, it has proved to be a useful source for hybrids and varieties. Many of the finest modern lilacs were raised from this species by Dr Isabella Preston, who worked in Ottawa, Canada during 1920’s. One of the most popular of her hybrids is Bellicent a large arching shrub with clear pink flowers trusses about 25cm. Which appears in May? Traditionally, lilac used to play an important role in folk medicine, the flowers and bark being used to reduce fevers. Lilac must have made an unpleasant medicine since it has an extremely bitter taste. The wood from a lilac shrub has few commercial uses nowadays, though in Victorian times it was used for decorative inlay work.

Gloxinia or Sinningia speciosa

This is a very beautiful plant when in bloom, and this is when you are apt to receive it as a gift-a cluster of large bell shaped flowers rising out of a circle of large, dark green fuzzy leaves. After Gloxinia blooming goes into a dormant state during which the leaves and stems die and there is nothing left but a little, flattish tuber. The stunning Gloxinia is a genus of three species of tropical rhizomatous herbs in the flowering plant family Gesneriaceae, primarily found in the Andes of South America but Gloxinia perennis is also found in Central America and the West Indies, where it has most likely escaped from cultivation.

At this point most people throw the thing away, not realizing that they can keep growing it and re-flowering it for decades. Gloxinias come in many vibrant colors mainly in red, purple, pink and white some are spotted or edged with contrasting colors. You can purchase a gloxinia at any point in its life. It it’s in bloom you can see what the flowers look like of course but often it is easier and less expensive to purchase a tuber in midwinter, planting it about ½ inch deep in a soilless mix. Water it sparingly while it is starting to root, then keep soil evenly moist but not soggy while the leaves appear. Try not to get the leaves wet. Gloxinias will do well in a room, whose temperature is normal or cool, but the air should be fairly humid, and the plant should have bright light but not direct sun. Like other members of the gesneriad group, which includes African violets and streptocarpus, gloxinias do well under fluorescent lights give them 14 to 16 hours per day. Feed with a balanced or high phosphorus fertilizer once a month while plants are growing.

Moreover, after bloom stop feeding and gradually stop watering. When the leaves turn yellow and the plant goes dormant you can either leave the tuber in the pot or repot it in a slightly larger one, then store it in a dark, cool place about 50degrees, keeping the soil almost dry until a few months later when new growth starts. Or you can dig up the tuber and store it in peat moss for at least forty five days.  Then place it in barely moistened peat or a soilless mix when you want it to start growing, just as you do when you buy a new tuber. New plants can be propagated by dividing the tubers just when they show eyes, making sure there is an eye for each division or by taking leaf cutting. Gloxinia is a perennial flowering plant, but many hybrids are grown as annuals.

Golden Chains of Laburnum

The spectacular springtime show of yellow flowers gives laburnum its common name is “golden chains” or “golden rain”. But the laburnum also has its dark side, for it is one of the most poisonous trees growing in the British Isles. Like so many of the more colorful trees that grow in Britain, the lovely laburnum is not native to this country. It comes from the mountainous areas of central and southern Europe and was familiar to the ancient Romans. A great naturalist, Pliny the Elder, described it as a “tree from the Alps” with hard white wood and long yellow flowers which bees will not touch. He was right that honey bees are not attracted to this tree, because its flowers do not produce nectar. But the wood is not white; the sapwood is butter yellow and the heartwood is a dark chocolate-brown. Nevertheless the name laburnum is derived from the Latin for white sapwood.

From its native countries, laburnum was slowly introduced to the rest of Europe and reached in Britain in the 2^nd half of 16^th century. The first laburnum to be introduced to this country was the common laburnum (laburnum anagyroides). This was followed about 30 years later by another species laburnum alpinum, which was found to grow much better than the common laburnum in the harsher conditions of Scotland. This laburnum is now known as the Scotch laburnum. A third laburnum, now more widely planted than either of the other two, is Voss’s laburnum (Laburnum x watereri). This is a hybrid between the common and the Scotch laburnum and is in many ways superior to them, particularly in its flowers. It also has a narrower crown, which makes it popular in small garden. All laburnum species flourish in the British Isles; indeed, they have become adapted to the British climate better than any other introduced tree. Not surprisingly, both the common and the Scotch laburnums became naturalized soon after they were introduced helped also by the fact that both species set seed abundantly. The best place to see a naturalized laburnum is in wild hilly country.  

Apart from some differences, laburnums resemble each other closely. They are small trees, growing no more than 9cm high which is why they have long been popular as street trees and for planting in small town gardens. The bark is smooth and olive green sometimes turning brown with age. The trunk is slender, seldom exceeding 30cm in diameter. The leaves are unusual in that each consists of three short stalked leaflets laburnum is the only tree commonly grown in the British Isles to have this leaf arrangement. The leaflets are up to 8cm long; their upper surfaces are pale green and smooth, the lower surfaces light grey and hairy, however hairless on the  Scotch laburnum.

Moreover, laburnum is a member of pea family and this is shown in the shape of its flowers. These consist of five bright yellow petals arranged in typical pea fashion one large standard petal two wings and two more connected to form a keel. The flowers are borne on long pendulous racemes that vary in length from 15cm to 30cm. On the Scotch laburnum the racemes are bit longer than on the common. But they are also narrower and the flowers are more widely spaces. The Scotch laburnum blooms later around the end of June, which is about three weeks after the common laburnum. The flowers of Voss’s laburnum combine the best features of the other two; its racemes are as long as those of the Scotch laburnum, but the flowers are larger and more densely borne, like those of the common laburnum.

All plants in the pea family have their fruits borne in pods. In the case of the laburnum, these pods are slender, hairy and light green when immature. They turn brown and lose their hairs as they ripen in July and August. When the pods are ripe they twist and split along their margins, forcing out the small hard seeds these are black on the common laburnum and brown on the Scotch laburnum. One or two seeds at the stalk end of the pod are often left behind if the twisting action was not strong enough to force them out. If the tree is growing in the wild this has the advantages of spreading out the interval at which the seeds are distributed, and so increasing the chances of a seed finding conditions favorable for germination.

Although the laburnum is widely planted for its beauty it is nevertheless, an extremely poisonous tree in all its parts roots, leaves, flowers and seeds. The seeds are particularly poisonous and every year there are cases of young children falling ill after eating them. There are also a few cases of cattle being poisoned after browsing on the pods, though rabbits and hares seem to be unaffected. The poisonous nature of laburnums is another reason for the popularity of the hybrid Voss’s laburnum. As well as having prettier flowers than either of the other two, it produces far fewer seed pods and so attracts children less. The seeds themselves and other parts of the tree are just as poisonous as on other laburnums, however. As described above, that all parts of laburnum, especially the seeds are highly poisonous. Symptoms appear an hour after ingestion. The victim suffers from a burning sensation in the mouth, nausea, severe thirst, abdominal pains, sweating and headache; in severe cases death follows. However, it is very rare chance that children eat a lethal quantity of seeds approximately 15 to 20. Nevertheless, immediate treatment by a doctor is advisable eve if only one or two have been eaten.

Over the centuries laburnum wood has been greatly prized by cabinet makers for its hardness and its contrasting colors. The difference in color between the sapwood and the heartwood has given rise to what is known in the furniture trade as oyster work. These are small discs or roundels of wood formed by cutting across a laburnum branch to expose concentric rings of growth. The inner rings are chocolate brown heartwood and the 3 or 4 outer rings are butter yellow sapwood. Laburnum branches an also be cut at an angle to give oval slices. Both sorts of cut are used for decorative inlay work and veneers. Furniture carrying oyster work was particularly popular during the reign of William and Mary; today it fetches a high price at auctions. Laburnum wood is also ideal for turning work fruit bowls, egg cups and so on since it is hard, close grained and takes a high polish. Pulleys and blocks made from laburnum last almost forever, and the chanters on Scottish bagpipes are frequently made from this wood because it can be bored accurately.

Clivia Miniata A Prettier Indoor Plant

Clivia miniata also “Kaffir lily” grows from a thick rooted bulb. It is a species of flowering plant in the genus Clivia of the family Amaryllidaceae, native, growing in woodland habitats. It looks something like the more familiar amaryllis, to which it is related, but I think it is prettier and its clusters of orange, red or gold flowers more subtle than the huge amaryllis flowers. Flowers can appear any time from December to April, however mostly appears in March. The flowers are rising on 18-inch stalks from the tidy, dark green, strap like leaves and opening over a period of several weeks. Most plants get about 2 feet tall but there are more compact varieties.

Moreover, Clivia’s are very easy to grow plants once you understand them. They will take morning or late afternoon sun, but too much midday sun will scorch the leaves. Hence bright indirect light all is best. Give them average room temperature and humidity by day, but cool temperatures at night if possible. During the dormant period before bloom, a temperature of 50 to 55 day and night will help to induce bloom. Clivia’s like an organic soil like that used for African violets and need to be pot-bound in order to flower. Clivias don’t appreciate root disturbances; however, repotting can be done every three to five years in spring once the flowers have faded.

Repot only when the roots are crawling out of the top of the pot. A heavy pot is often necessary to keep them from tipping over. In the spring and summer season you need to keep the plants evenly moist, fertilizing every two weeks. A summer outdoors in filtered sun will do your Clivias well. Also, bring them in before frost, and stop feeding them. Starting around thanks giving, give them little no water, and if possible keep them in a cool room that gets no light in the evening. When a flower stalk emerges, bring the plant into a warm, light place and start feeding and watering it again. Moreover, plants may be propagated by removing and replanting side bulbs in spring when new growth starts.

Blanket Flower

Gaillardia common name blanket flower is a genus of flowering plants in the sunflower family, Asteraceae, native to North and South America.  Blank Flower “Gaillardias x grandiflora” is look like large daisies, with bold, bright markings like those of an American Indian blanket, in patterns of red, yellows and gold’s. Mostly grow about 2 ½ feet tall, but there are also dwarf varieties. They bloom in summer over a long period and are a good choice if your climate is hot and dry. Varieties include the mixed colored “Monarch Strain” and solids such as dark red “Burgundy” and Yellow Queen. Multicolored Goblin grows a foot tall.

 

It is resemblance of the inflorescence to the brightly patterned blankets made by Native Americans, or to the ability of wild taxa to blanket the ground with colonies. If you want to grow a permanent long season of bloom, blanket flower is a great choice. The daisy-like flowers are formed from early summer to early fall in a different shades of orange, red and yellow, adding up sizzle to the garden and enticing nectar-seeking butterflies.

The stem is usually branching and erect to a maximum height around 80 centimeters. The leaves are alternately arranged. Some taxa have only basal leaves. They vary in shape. Blank Flower needs to grow in moist humid areas the plants may develop fungus diseases in summer or succumb to rot from winter moisture. Moreover, you need to avoid mulching them and given them light, well drained soil, preferably on the sandy side. Gaillardias can be grown fairly quickly from seed, and will flower the first year. In spring, you watch from new shoots that may appear quite a distance from the original clump. If the center of the clump dies, discard it and replant the side shoots.

Many cultivars have been bred for ornamental use. Thus care of blanket flowers includes planting in a full sun location to keep this fast growing specimen happy. As a native plant to the central United States and Mexico, blanket flower is a heat loving flower are drought tolerant and do not like wet feet from soggy soil. Growing blanket flowers can naturalize in a meadow or field adding hues of color. Easy care of blanket flowers makes them an ideal specimen for many landscape uses.
