Neutral lmelling On Jan 13, 2005, lmelling from Ithaca, NY (Zone 5b) wrote:

Large, vase-shaped mound of cupped, blue-green foliage 30" high by 66" wide. Space about 60". Leaves are 12" long by 9.5" wide, ovate to broadly ovate shape with a heart-shaped base and distinct tip. They are deep blue-green early, changing to dark green by mid-summer. Thick underside bloom. The blade is distinctly cupped upward and held perpendicular to the nearly upright petioles. Leaves also have moderate to heavy corrugation; no red dots on petioles. 13-14 vein pairs.

Pale, funnel shaped lavendar flowers with white petal margins and darker streaks leading into the whitish throat - in late July into August. Scape size is outstanding and can reach 54" or more. Pod formation is sparse, but several hybridizers have made some significant introductions such as 'Krossa Regal', 'Flower Power' and others.
