Blue Iris needs ID

Iris versicolor, easy from seed, is a more northern species that does very
well here. I. virginiensis, supposedly native to Indiana, is not so
vigorous in my garden; but I have it in light shade. I. fulva lasted a few
years and bloomed nicely, but dwindled gradually away.

All of these will thrive and multiply vigorously if given plenty of
moisture. I grow mine in a pond with the rhizomes just below the
surface of the water (this prevents iris borer from damaging them).

I have a spectrum of Iris fulva ranging from yellow to dark red, with
just about every step inbetween. The big hit this spring was one
nicknamed "butterscotch". It was delicious! :-)
