Dymondia margaretae ~ Silver Carpet
Dymondia is a popular lawn substitute. It will handle moderate traffic and survive on a much lower water regime than grass. Don't be mislead by the photo, the 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. The roots do well with the extra protection of the stone. It has survived my three dogs and kids with almost no additional water, though it gets scruffy in the high traffic zones. Dymondia is native to the coastal plains of South Africa. It is hardy to 20° F.
