Desert ephemerals are plants which are adapted to take advantage of the short wet periods in arid climates. Mud-flat ephemerals take advantage of short periods of low water. In areas subjected to recurring human disturbance, such as plowing, weedy ephemerals are very short-lived plants whose entire life cycle takes less than a growing season .
The diversity of climatic conditions, though quite harsh, supports a rich array of habitats. Many of these habitats are ephemeral in nature, reflecting the paucity and seasonality of available water. [1] Woody-stemmed shrubs and plants characterize vegetation in these regions. Above all, these plants have evolved to minimize water loss.
Tepary beans are very drought tolerant. Germination requires wet soil, but plants will flourish in dry conditions once established. [10] Too much water inhibits bean production. They were cultivated by various methods, most commonly after an infrequent rain in the desert or after flood waters along a river or ephemeral stream had subsided.

Selaginella lepidophylla is a true resurrection plant that can revive and regain metabolic function after a period of extreme desiccation. Anastatica hierochuntica is not a resurrection plant, but rather a tumbleweed also capable of repeated expansion and retraction, which superficially resembles revival.
