Gardeners' Notes:

34" EM
I no longer grow this iris because I lost it several years ago after flooding here in Virginia. But I did grow it for about 5 or 6 years. It grew very well here, forming a nice showy clump after 2 years. The flowers are medium sized, abundant, and brightly cheerful. It always stood out in my garden. I recommend it and have just planted a new rhizome this year.
