I'm looking for a reasonably good-looking low rapid-spreading ground cover
for poor, dry, stony, alkaline soil. Some areas of my sunny but windy south
coastal plot, consist af a soil which is about 90% white limestone dust
with only about 10% organic matter. I'd like something that spreads quickly
but is also easy to keep under control. If it keeps it's leaves year-round,
that would be most suitable. Any suggestions?

Thank you...
