Additional Comments:
Photo shows cultivar 'White Fall' (J. McGary, 28-APR-04)
The cultivar 'white fall' is said to be a hybred with I magnifica, 'yellow fall' is said to be a hybred with I bucharica, I graeberiana as I grow it looks almost identical to I zenaidae (ex Ruksans), and a plant I bought as I albomarginata, but I believe this is I albomarginata-hort and not the real thing. I also have I graeberiana 'dark form' which has a slightly more spindly flower with a much better colour. All these plants are hardy in the open ground, well drained, in England (Peter Taggart UK, 05-JAN-10)
