On the other hand, due to its high bud count when mature Siberia usually outlasts other Oriental lilies I have grown. By this I mean days of bloom from first to last flower. Blooms are held closer to the stem in a columnar formation.
According to B&D their white Oriental lily Ice Dancer (Late July / Early August) blooms a little later than Star Gazer (July). But maybe that is too late for you.
