Dear all; It is easy to be confused by the array of iris involved here. The original Aril species are generally more difficult to grow and demanding especially in regard to annual watering schedule and drainage. I did not mean to recommend them for the novice. The aril-bred hybrids are much easier and very rewarding. Even up to the Canadian border at least and even easier in Mediterranean climates, but even here in the mid-west most cvs do exceedingly well, bloom regularly and multiply with vigor. I have donated extra rhizomes to ASI sale a couple of times. I am certain California Iris nurseries sell a wide range of cvs suited to your various micro-climates, but there are also hybridizers on the E. coast and all over the US developing easier to grow, nicely patterned hybrids. I grow a few species, and prefer hybrids that are at least 1/2 species to get the most "species look" possible and still not too demanding. Come on people- You can grow these. You deserve it.
