Pretty, fun and frilly. In my north-facing home, I'm happy to have these blooming early... about two weeks behind the flowers on the other side of the street, but still ahead of everything in my yard except the super-early crocus.

Raised by famous Latvian bulb breeder Janis Ruksans during the 80s.
Blooms rosy, edged white, iside: white with a yellow base. This cultivar has quite unique flowers resembling somewhat tulipa clusiana in shape. Very early flowering, tall growing population from Ugam mnt. range, Uzbekistan. It is one of the tallest - up to 45 cm high and the earliest tulipa kaufmannianas, blooming at the same time with Dutch crocus vernus hybrids.
Recently regestered in Hollad by J. Pennings under the name 'Ice Stick'.
