Crassula connata

Sand pygmyweed

A tiny annual or short-lived succulent, only a few centimetres tall, from western North America and parts of Central and South America. It forms small patches of fleshy millimetre-long leaves on sandy or rocky ground and in vernal pool margins, turning from green to pink and red as it matures. In cultivation it is best treated as a cool-season annual grown from seed for a pot, trough or rock garden.

Where it grows wild

Grows in patches on open sandy and rocky ground, and is sometimes associated with vernal pool communities. It sprouts with the cool-season rains, flowers and sets seed, and dies back as the ground dries.

No elevations are available from the data. In western North America it is largely a lowland and foothill plant.
