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
