I did a google search and although I know nothing about this company, it's the only place I found it listed for sale, Cascadia iris Gardens in Lake Stevens, Washington: https://www.cascadiairisgarden...

I got mine from Caacadia Iris Gardens mentioned above. They ship in the spring so your plant has a whole season to settle in. DB bloomed the longest of my irises this past year, almost a month. Huge garden presence!
