>You didn't mention it's coolest trick: transforming between rhizomes to >bulbs and back! Dear Dennis... since you asked... Yes I. anguifuga has a number of tricks up its sleeve. If you dig the plant in bloom, you'll find what looks like a husky rhizome, but as it goes dormant over summer the rhizome shrinks back to a very short stubby 'rhizome' with a terminal bud that sort of looks like a typical bulb. This reserve is able to produce the fall leaf growth. Presumably between the initiation of foliage in fall and the withering of flowers in spring, the rhizome is able to extend its growth and look perfectly normal again by spring. If you , like me, wonder how the genus Iris can include both rhizomateous and bulbous species, this one gives you some insight into how one anatomy can change to another. Oddly this species does not live in a climate that has weather extremes or drought. Wonder where this odd change of form arose. I find this all extremely interesting stuff.
