All Bulb and Corm Flowers

Flowering plants that store their energy in an underground bulb or corm and send up leaves and flowers from it each season, such as the Madonna lily and the saffron crocus. A plant belongs here when its cited plant database page gives its growth form as a bulb or a corm. It excludes the fibrous-rooted perennial flowers and the annual flowers, which grow from seed each year. The buried storage organ lets these plants survive winter or drought and flower on a fixed schedule, which is part of why the lily and the crocus have long been tied to purity, resurrection and the turning of the seasons.
