Ebracteola wilmaniae

Ebracteola wilmaniae is an outstanding South African succulent forming compact highly branched rosettes of trigonus gray-green leaves.  The white to dark-pink flowers appear in early spring  and flowering continues sporadically throughout the growing season.  A slow growing mat will form with age.  This species has proven to be reliably winter hardy  for us in Colorado. Plants have taken -11F and have not been tried past this. This would be a good plant to trial in your Zone 5 or better garden.
