Other info: The only difference I can see in the polemonium coeruleum and viscosum is the plant height. Flowers are pretty much the same. Actually, after further study, I think the flowers are a bit paler on this variety and bloom time is 4-5 weeks before polemonium coeruleum. The plants bloomed very early and were just lovely!
