Positive coriaceous On Mar 12, 2015, coriaceous from ROSLINDALE, MA wrote:

Very showy flowers, with an exceptionally long season of bloom, from June till frost. The flowers are no larger than those of other soapwort species. Plants can be short-lived---excellent drainage is essential.

Sterile, can be propagated by rooting cuttings. The woody rootstock is difficult to divide.

This is a hybrid between S. cypria and S. sicula var intermedia (aka S. haussknechtii) made in mid-twentieth century Austria by Fritz Lemberg. 'Max Frei' is the only cultivar.
