grow a few .....maybe 15, or so. "Basic" culture is about the same as bearded.....lots of sun, and good drainage, although I plant them about 2 inches deep, instead of "on the surface", and mulch them with pine straw, for the first year after planting.soil ph doesn't seem to be an issue for them, as most are planted with the bearded irises, but some are in my "beardless bed", which has been "acidified". Like other beardless....when they are "out of the ground", the rhizomes need to be kept damp, and they will.....when it's very dry, benefit from a good watering(although ,my soil is VERY sandy, and possibly in heavier soils, watering may not be as important)
All -in - all, I would say they are the easiest of the irids to grow.
