Positive coriaceous On Jan 22, 2015, coriaceous from ROSLINDALE, MA wrote:

The breeders, Marty Schafer and Jan Sacks, have written:

"Not on the color wheel. Falls are yellow overlaid with blue and have large, round deep yellow signals. Standards are paler blue over yellow. Pale blue styles have yellow tips. Depending on conditions, flowers open in a range of tones.

"The vigorous clump has smallish flowers, four blooms per stalk and produces many stalks."

25" tall.

Schafer-Sacks irises have won many awards, including 7 of the last 9 Morgan-Woods Medals, the highest award given to a Siberian iris by the American Iris Society.
