Dymondia margaretae * Silver Carpet
Dymondia margaretae is a popular lawn substitute. It will handle more than moderate traffic and survive on a much lower water diet than grass. Don't be mislead by the photo, the yellow flowers are 1/2" across at best and can often be much smaller in drought or high traffic conditions I frequently use Dymondia between stepping stones. And sometimes to stabilize a steep edge to a pathway. The roots do well with the extra protection of the stone. In my garden Dymondia margaretae has survived my three dogs and kids with almost no suplimental water, though it gets a little scruffy in the high traffic zones. Dymondia is native to the coastal plains of South Africa. It is hardy to 20° F.
