I have planted Raoulia between stones in a walkway, and it is deliriously happy. Also have it on a west facing slope, both are full sun, hot as the dickens in the summer, clay soil underneath the patch on the slope and underneath the sand between the paving stones. I've now got so much of it I am giving it away. Great little plant! tough, pretty, lovely texture.

Imagine a prostrate, crusty, silvery mat of small, leathery leaves that are only 1/8" long and you have Raoulia australis. The small, pale-yellow flowers are insignificant. Coming from the alpine screes of New Zealand, it needs good drainage to survive, especially through the winter. In summer your Raoulia will need average moisture.
