How to Make Crocuses Bloom in May

Often considered bulbs, crocuses are actually corms that are native to Asia and Europe. Unless you live in a cold climate in which winter lasts well into March or April, the crocuses in your area probably bloom earlier than May. Since crocuses are some of the first flowers to bloom in the spring, they won’t last into May unless you force them to bloom at that time. Their bloom can be controlled with the proper chilling period.
