Geophytes

 

perennial plants whose organs are equipped to overwinter or endure prolonged drought and whose renewal buds (on rhizomes and tubers and in bulbs) are hidden in the ground. Geophytes are one of the life-forms of plants. The parts of geophytes that are destined for life under unfavorable conditions are protected by the soil, and during cold winter, by the remains of dead parts of plants and by snow. Many bulbous plants (for instance, the family Liliaceae), rhizomes (including many grasses and sedges), and tuberous plants are geophytes.
