Crassula longipes

A tiny annual pygmyweed (formerly placed in Tillaea) of seasonally wet ground in the southern United States, Mexico and south-eastern South America. It is an ephemeral that germinates in wet periods, flowers and sets seed within weeks, then dies; it is kept by re-sowing, not as a long-lived succulent.

Where it grows wild

Grows on bare, seasonally wet ground: muddy flats, shallow rock pools and seepage on granite or sandstone, drying pond margins and disturbed damp sand. It is only a few centimetres tall and depends on open, unshaded patches.

Mostly lowland in the United States; the few elevation-bearing records (2255–2824 m) come from Mexican highlands.
