Poincettia pulcherrima- red vareity
Botanical name:Euphorbia pulcherrima/Poincettia pulcherrima.
Family::Euphorbiaceae. It is a shrub or small tree, typically reaching a height of 0.6 to 4 m (2 to 16 ft). The plant bears dark green dentate leaves that measure 7 to 16 cm (3 to 6 inches) in length. The colored bracts—which are most often flaming red but can be orange, pale green, cream, pink, white or marbled—are actually leaves; because the flowers are unassuming and do not attract pollinators, brightly coloured leaves developed (aka bracts). The colors come from photoperiodism, meaning that they require darkness for 12 hours at a time for at least 5 days in a row to change color. At the same time, the plants need a lot of light during the day for the brightest color.[4]
Because of their groupings and colors, laymen often think the bracts are the flower petals of the plant. In fact, the flowers are grouped within the small yellow structures found in the center of each leaf bunch, and they are called cyathia.
The species is native to Mexico.
This is a common hedge plant in west-coast of Karnataka. In cities, it is a decorative plant of great demand.
