I've had soapwort in my garden for almost 10 years and it's one of my favorite ground covers. It keeps weeds out very well, and the lovely pink flowers in spring draw attention and compliments. It does reseed quite easily, but I have never had any problem keeping the plan under control. It does best with south or west exposure, and looks wondering tumbling over rocks, a slope or a retaining wall. I have it sitting next to beds of light blue phlox and white candy tuft. The blooming time is staggered for each, but the color palate is gorgeous during the week or so where all 3 are blooming at the same time.

This plant was great in an urn in a hot, sunny dry part of my yard. After 2 - 3 weeks of beautiful blooming, I cut it back hard and the leaves filled back in for the rest of the summer and well into fall. It takes very little care.

This makes a great nursery plant for areas where other, slower growing groundcovers are to be grown. It spreads very rapidly, preventing weeds while new plants are establishing. It can be difficult to eliminate, though.
