Not native here, but I planted some along a woodland edge. It seems fairly tolerant of spots that aren't overly moist here, but we get fairly regular rainfall. This shows that growth habit in my yard, though the blooms are starting to fade.

They are lovely in the wild and in cultivation. The color range is wonderful.

That is a very nice bed of cristata NHBabs. Those plants seem to thrive in drought, floods, heavy shade, and even in poor soil, so should be a well-mannered plant in a garden. I'll bet they would also do well at your location peren.

I love irises - thanks!
