I’m going to paraphrase the Pacific Bulb Society entry here since this is the clone I’m offering: Sternbergia greuteriana Kamari & R. Artelari, although a published name, is considered by Kew to be a synonym for Sternbergia lutea. This species or form is smaller and the first photo from Jane McGary of plants grown from purchased seed of garden origin includes a flower of S. lutea for comparison. S. greuteriana is easy to grow in an unheated bulb frame, increasing modestly.

I’ve grown this clone for years in an unheated greenhouse that protects from excess winter wet. This is a special clone and a must have for anyone interested in fall blooming bulbs.
