How much darkness do poinsettias need?
Twelve (12) hours 20 minutes of uninterrupted darkness for five (5) days straight is the amount of darkness that poinsettias (Euphorbia pulcherrima) needs in order to bloom.Specifically, that is the requirement that must be met sometime between September 20 and October 20 in order for poinsettias to bloom in December. Such is the natural bloom cycle for poinsettias as long as other critical conditions such as air and soil moisture, light intensity, nutrition and temperature are met. But in fact, anytime that poinsettias undergo the above-mentioned short day/long night cycle they have the potential to see the flowering process initiated and their modified leaves change in color from green to red 65-85 days later.

Where do you find the flowers on poinsettias?
The tips of the stems are the locations of flowers on poinsettias (Euphorbia pulcherrima).Specifically, the flowers are dainty, inconspicuous, and yellow when they bloom. They are surrounded by true and transitional bracts. Bracts are modified leaves. The true bracts immediately surround the flower. They are always bright red in color. The transitional bracts are located between the true bracts and the plant's regular leaves. The transitionals start out green in color. But they undergo changes that culminate in their surfaces turning bright red by the time that the flower blooms in December.The red of the true bracts and the reddening of the transitionals may be protective adaptations by which poinsettias protect their flowers.
