Saxifraga x arendsii 'Purple Robe'
Arend's Saxifrage or Moss Saxifrage Saxifragaceae:
Mat forming foliage with succulent leaves. The 5 to 8 inch tall flowering stems end in reddish-purple flowers. Low fertility soils required, best in sand based soils that are well drained. Grow in full sun or part shade. Will not thrive under hot, dry conditions.
Surface sow the very small seeds on top of a already moist seed medium (mixed with some clean sand is helpful) and keep at 50-65F with some germination in a few weeks. For best seed germination: Sow in the fall and keep pots outside over winter for spring germination, needs a few months of cool, moist conditions. The seedlings start off life growing very slowly, so care should be taken to not allow them to dry out.
