Pionsettias are short day plants. That is, flower initiation follows
after a month or two of days less than 12 hours in length. The flowers
are the usual small euphorbia types, subtended by bracts which we
usually call flowers. Commerially, these plants are started from
cuttings in June, and grown very quickly for a few months, after which
they are given artifical darkness for about 15-16 hours a day.
