Rock Soapwort Saponaria ocymoides

It is not without reason that rock soapwort is a popular garden perennial: it requires little care, grows flat, and can be pruned back in early summer to return to bloom.

Saponaria ocymoides is native to Europe. It grows in mountainous regions. It has also reached North America as an ornamental (source).

According to my observations, the rock soapwort tolerates soils that dry out well, but not for long. So it should not be treated like a cactus. The related snow-in-summer (Cerastium-tomentosum) is better suited for such sites.

Nutrient-poor soils are not a problem.

Saponaria ocymoides grows well in full to partial sun and can be used for planting in large containers or against walls.
