Steve Garvie wrote: These were raised from GBG seed, probably from a collection made in NE Sikkim. They look fairly similar to a form of nanum that was once briefly commercially available called “Bhutan Blue”. Looking at the map, Sikkim does have a border with Bhutan. Whilst not true blue they are perhaps the closest to blue that I have ever seen in a lily.
