Wonderful post, John. I wish others would do this more. Yes, Iris cristata has white-flowered forms. In strict observance of the usual horticultural muddle, they are generally called 'alba'. What did you mean when you said that the iris and the magnolia have opposite soil requirements? You didn't mention the magnolia in question, but magnolia soil in general should suit the iris very well. In fact, for years I had a broad mat of Iris cristata under Magnolia stellata. You have Japanese iris in bloom already in Ohio? Habenaria [Sometimes Platanthera/Pecteilis] radiata is a tiny plant with leaves only about a half inch wide and at most a few inches long. When in bloom it might stretch to nine or ten inches high. It grows best for me under bog conditions: in live sphagnum moss is ideal. If you planted it in garden soil, you'll probably never see it again. You wrote: "and another [Allium] muddy white one with wide grey leaves from Brent and Becky's. This one is about 4" tall with 3" umbels. The name escapes me at the moment." If that's 4' instead of 4", your plant is probably the Allium sold as A. multibulbosum or A. nigrum. I love variety and abundance in a garden, and the one you described seems to have both. Sounds wonderful, and thanks for sharing.
