Magnolia


Well, magnolias are handsome ornamental trees, with their showy flowers, their dark green leaves and their relatively small size. Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. They are generally thought of as southern plants, but there are species that will do well in the north,, even though they may not make you feel like Scarlett O’Hara. Saucer magnolia (magnolia x soulangiana) grows about 25 feet tall, normally with several trunks, with smooth, dark gray bark. The large flowers, white streaked with pink and purple, sit upright at the tips of the branches before the leaves appear. Star magnolia is a considerably smaller tree the flowers, which appear quite early in spring, are like large fragile white stars. The natural range of Magnolia species is a disjunction distribution, with a main centre in east and Southeast Asia and a secondary centre in eastern North America, Central America, the West Indies, and some species in South America.

The foliage is much finer textured than that of saucer magnolia. Bothe are hardy, but in cold climates are best grown in a partly shaded exposure to retard bloom early flowers can be killed by cold, and late snowstorms can turn start magnolia blossoms into tattered wrecks. Southern magnolia, also called “bull bay” (M.grandiflora), is a native ever green single trunked tree that can grow as tall as 90 feet, though it is usually a good bit shorter. It is hardy though it may survive farther north if grown in a sheltered location. It has huge, glossy, dark green leaves and fragrant white flowers that can be as large as a foot across. Its seeds pods, which open in fall to reveal red seeds, are also ornamental.

Magnolias normally like full sun, except in the situation described above, and except for southern magnolia, which is fairly shade tolerant. All like fertile, loose, well drained soil that is rich in organic matter, with a slightly acid pH. Magnolias do not transplant easily and should be planted balled and bur lapped in spring. The roots are shallow, and care should be taken when cultivating around them. Moreover keep the soil moist while the trees are becoming established, and mulch them. Magnolia scale can be treated with a dormant oil spray. Magnolias do not respond well to pruning because the wounds do not heal easily. But any dead or diseased wood should be removed. Remove water sprouts,, suckers and any undesirable branches while they are small, if possible, pruning softer flowering in early summer. Spent blossoms can be removed for better bloom the following year, but usually magnolias bloom prolifically on their own. The shorter kinds can be trained to one trunk or allowed to be shrub like.  Source: Charismatic Planet

Zinnia Flower


Zinnias are tender annuals that all gardeners love because they make a great show and are easy to grow. Zinnia is a genus of plants of the sunflower tribe within the daisy family, native to scrub and dry grassland in come in a variety of bright colors. The genus name honors German master botanist Johann Gottfried Zinnia. Zinnias are annuals, shrubs, and sub-shrubs native primarily to North America, with a few species in South America.

Flowers are flat or rounded heads of petals, like overlapping scales, in every color except blue. The height and flower sizes may vary. However, modern hybrids are derived from Zinnia elegans, Z. angustiflia and Z. haageana, and range in height from 12 inches to 3 feet. Large, tall zinnias such as the Zenith strain or the California Giants are good for the back of the garden. Cut and Come again, zinnias are bushy plants of moderate height that are full of button like flowers and bloom all the more if cut. Thumbelina zinnias grow about 6 inches high and all bloom until frost, and none need staking.

Moreover, to grow zinnia you can sow seeds indoors about 4 weeks before the last frost and set out in moist, fairly rich soil 8 to 18 inches apart depending on the size of the variety. Large zinnias will not branch properly if planted too closely. Too close planting may also lead to mildew. Use peat pots since they do not like to be transplanted. Since zinnias germinate and grow so quickly. It is also possible to sow them directly in the garden after danger of frost. Leaves may mildew, but this will not affect bloom. If the mildew bothers you, use a fungicide. Water in drought,, but try to keep water off the leaves, since this can make the mildew worse. Zinnias are warm weather plants and make excellent long lasting cut flowers.

The Scilla Flower

Scilla is also known as Squill is a genus of about 50 to 80 bulb-forming perennial herbs in the family Asparagaceae, subfamily Scilloideae, native to woodlands, subalpine meadows, and seashores throughout Europe, Africa and the Middle-East. Scillas have small bell like flowers that dangle from thin 3 to 6 inch stems. Most gardeners love blue Scilla which mixes brightly with pinks, purple, whites, and contrast crisply with yellows and golds. The scilla family offers some of the best blues to be found anywhere. From the huge, striking blue of Scillia Peruviana to the smaller, carefree blues of tubergeniana and blue-purples of amethystine these sparklers belong in every garden that celebrates spring.
Most of the ones you will see in gardens and their color are blue, purple, lavender, pink and white scillas too. They are lovely in situations where their delicate beauty can be appreciated planted in woodland gardens, under the light shade of a deciduous tree, in rock gardens, or naturalized in lawns. Modern hybrids come from a number of species, most commonly Scilla siberica. S. tubergeniana has fewer flowers on a stem but more stems to a plant S. bifolia, the twin leafed squill, has more open flowers.
The precise number of Scilla species in the genus depends on which proposals to split the genus are accepted. S. hispanica (S. campanulata), Spanish bluebell, is quite tall usually over a foot and a good choice for shady location. The hardiest of all these is S. siberica, which will survive in cool climate plants. But if you want to grow S. peruviana, which is a foot tall usually purple, like the names of many bulbs, S. peruviana’s name is a geographical muddle; though both its Latin name and its common name, “Cuban lily”, give it a Latin American origin it is really native to the Mediterranean region.
