Many of the Delosperma species have 'pinkish purple', 'violet', or 'magenta' flowers (whatever the vendors think sounds best), and look very similar.

I am about to sow the seed of this plant, and will keep you updated on my progress. So far I've only been successful with D cooperi, but this one sounds promising.

I think I've seen it growing in Falmouth -- the bright white centres distinguish it from D cooperi, but it disappeared after the winter. Perfect drainage is essential -- little more than hardcore with 10% soil would probably be best.

Alas, I doubt this is a true Zone 4 plant, especially an Eastern Zone 4. I have problems with it in zone 6...the late winter/early Spring rains usually finish it off. Delosperma John Profitt is the most hardy pink hybrid in Connecticut, a similar flower to Starburst without the white center!

This is such a fascinating plant. The leaves really look as though the have tiny ice-crystals on them! I like the feeling of them, too. And I haven't even mentioned the flowers yet . . . they bloom heavily and add a lot of color to areas that most other plants wouldn't even grow.

Update: Unfortunately, it did not survive the winter in any of the places I had it.
