Gardeners' Notes:

I grow these extensively in my back yard all year long and in So. Cal they are definitely not a slow-grower, they spread very fast from mid-spring to late summer. A real showy, nice ground cover that blooms nicely when the weather turns warm and doesn't stop until fall.

This is a tough little plant that spreads slowly and self-sows. Good for a xeriscape or rock garden.

I grew these this summer and they are beautiful! They do well in a container or in the ground. They filled the container nicely, then I transplanted them to the ground so they could grow even bigger!
