There are lots of hosta growers, especially around Cedar Rapids, and an iris grower in the SE part of the state. The Iowa Lily society is based in DM and we have our Spring sale during the Flower, Lawn and Garden Show at the fairgrounds. (Varied Industries Building) It's a lot of fun and there are all kinds of plants, bulbs and garden art to be had.
I've met AlwaysWeeding and BookerC by hanging with you fun Iowa people. Iowa has plenty goin' on!
