detailed seed-starting info below

Cushion-forming plant, suitable for rock gardens. Easy enough to start from seed, but my first two attempts to establish them in our garden were unsuccessful. In a third attempt, I managed to coax one plant through its first summer and winter, and transplanted it to our rock garden the following spring. It did OK, even bloomed (I didn't take a picture), and seemed fine until the summer drought did it in shortly after I took the photo at right. On subsequent attempts, I've had some more success (as well as more failures), with both the dainty 'Dr. Hahnle' variety and a white-flowered one.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.

Seed for this plant is included on my seed trade list
