We found these in a garden store here in Salem Oregon last summer. We wanted a flowering perennial groundcover that would cascade over a retaining wall. We planted in part to full shade. They are doing great there and spreading rapidly. They don't need a lot of water - weekly watering during dry weather has been enough. They have small but abundant white star-like flowers that bloom continuously, dying back a bit in the winter. People are always asking us what they are.

Groundcover that likes well-drained
average sandy or loamy soil. Plants
dislike acid soil.

Spreads slowly to form low,moss-like
mats of foliage. Shallow- rooted;keep
moist during dry spells.

Divide in spring or fall. Sow seed out-
doors in fall or inside in early spring.

No serioius pests or diseases.
