Poinsettia Euphorbia pulcherrima
ABOUT
Euphorbia pulcherrima is a perennial evergreen shrub, usually reaching a height of 2 to 13 feet. It has dark green toothed leaves 3 to 6 inches long.
The colored bracts, which are usually fiery red and in cultivated varieties orange, pale green, cream, pink, white or marbled, are often mistaken for flower petals because of their grouping and color, but are actually leaves.
The color of the bracts is created through photoperiodism, which means they require darkness - at least fourteen hours for six to eight consecutive weeks - to change color. They also need plenty of light during the day for their bright color. This is why they only bloom in winter.
Poinsettia flowers are unassuming. They are clustered in cyathia (small yellow structures located in the center of each leaf bundle, or false flowers).
In its natural habitat, it grows up to 10-15 feet tall.
More than 100 varieties of poinsettias exist today.
