Comments:

This is an extremely hardy and easy perennial that is fast gaining in popularity. It is a low plant at 10 to 12 inches with a spreading and trailing habit. It is a rapid grower making it useful in areas where quick cover is desired. Some references actually list it as a ground cover. It has loose sprays of single pink flowers in early summer. It is very effective flowing over a retaining wall. The foliage remains attractive all season.

Rock soapwort prefers full sun and light, well-drained soil of poor to average fertility. Division is not necessary but can be used as a means of increase. Pruning the plants back after flowering will encourage bushier growth and a tidier appearance.
