(Poinsettia, Christmas flower)
A native of Mexico and central America. Poinsettia is one of the most useful flowering shrubs grown throughout the world.
Description: Tall or medium – sized shrubs, height between 1.5-3 m, branches cylindrical, glabrous, hollow when green, latex milky. Leaves alternate, ovate, elliptic, 8-15 cm long, 5-8 cm broad, glossy green. Flowers in cluster, terminal or axillary; bracts colored, showy, oblanceolate or elliptic, crimson, yellow, rose, white, 10-18 cm long, 3-6 cm broad, in one or more rows.
Gardening: In tropical and subtropical climate poinsettia is grown in the open, both in ground and in pot, while in temperate countries it is grown in glasshouse with heating arrangement as poinsettia cannot withstand, frost or very low temperature. After flowering the potted plants are widely used for indoor decoration. Since poinsettia flowers in winter months and large clusters of colorful bracts remain fresh for 3-4 months depending on the temperature and humidity of the atmosphere, the pot plants are popular in temperate countries during Christmas for decoration when very few flowers are available for display indoors.
The poinsettia is a commercially important plant species of the diverse spurge family. The species is indigenous to Mexico. It is particularly well known for its red and green foliage and is widely used in Christmas floral displays.
The species is a tall, rangy shrub that grows to a height of 10 ft. It has large, dark green, oval leaves that are toothed on the sides and pointed at the tips. They emerge from smooth green erect stems. Flowers are borne at the stem tips in winter. The actual flowers are quite small (they are the yellow structures at the centre of the brilliantly coloured bracts) The bracts are actually modified leaves – in the species there usually are 8 to 10 bracts that are 4-7 in long.
Planting And Care
- You may use plant ties or just weave them through trellis sections.
- Fertilize the plant in spring just before new growth appear
- Pinch off the tips of the vines in the second year to promote branching which will fill the trellis with bushy growth.
- The vining plant is prone to spider mites, which can be combated with horticultural oil or neem oil.
