Positive lmelling On Jan 4, 2005, lmelling from Ithaca, NY (Zone 5b) wrote:

Record breaking leaf of 21" by 16-3/8" was measured in 1988 in Clarence Owens' original clump during the AHS national convention.

Average leaf size is 17" long by 13" wide; bluish green color changing to medium green to dark green by early summer. Broadly oblong-ovate, wavy and downwardly puckered with a rippled margin. Moderate corregation, good substance. Flowers late June into mid July with near-white flowers with pale lavendar mid-petal stripe. Scapes 31" - 35" high.

Best grown as a "focal point" of a shaded garden because of it's tremendous size 32" high by 72" wide.
