Saxifraga × arendsii 'Purple Robe' (Mossy Saxifrage)

Plant Profile

Saxifraga × arendsii 'Purple Robe' is a charming, mat-forming perennial that creates a dense cushion of tiny, moss-like, evergreen rosettes. In spring, it erupts with a profusion of small, star-shaped, deep purple-pink flowers held on short stems above the foliage. This hybrid saxifrage is a classic choice for rock gardens and alpine troughs.
