Amaryllidaceae, having common name(s) associated with the genus; Spider Lily, Surprise Lily, Hurricane Lily, Resurrection Lily, Magic Lily, Naked Ladies.
Sold to me as L. houdyshelii, though having similar flower color, it does not have the regal stature of the species. The winter foliage looks like L. radiata foliage, and it is a very prolific divider and bloomer, also sterile like the true species. I have been very pleased with this variety's performance. Ht. 24 inches. Hardy in zones 7, 8, 9, 10.
Paying for three bulbs gets you FOUR!
