I believe that Christie is absolutely right. This could be Opal Star or Ruby Star. The two are considered siblings that are virtually identical, and sold interchangeably. emaryllis.com has posted the photo of Ruby Star. I have posted a photo of Opal Star on the NGA database. Depending on the light, the white areas look more of a very pale green. This is my all-time favorite cultivar for planting in the Southern garden. It is foolproof and hardy, and produces more blooms with each passing year.
