Christmas kalanchoe needs long fall nights in order for new buds to grow, if rebloom is going to be possible at all.
The glossy, green, succulent leaves are borne on compact plants that are topped off with thick clusters of red, pink, yellow, or orange flowers. The flowers can last for months.

Christmas kalanchoes are not hard to maintain in bloom, but getting them to bloom again is not easy. In the fall, subject them to 14-hour nights for two months or until flower buds appear. They are often best discarded when blooms fade and purchased in bloom the following year.
