I find Swertii very lovely, and it is a very good grower; always blooms; has good increase. My grow to 27-28 inches. The falls do curl, but that's part of its charm.

This iris can be found in the 1930`s AIS check list. It is shown as a TB, but my plants are very short. About 18" high.
It has small blooms, about 3", and it blooms midseason. It always has the falls curled up.

Everything about this plant is about the same size as most tall bearded irises except for the bloom. The bloom is tiny and I find it kind of ugly unless your up close and personal with it. Then as you can see from the photo it is kind of cute.

I guess you can say the tall bearded irises have come a long way baby since this one was introduced in 1612.
