Beautiful plant, having come from the north, I missed my iris. Spotted at the local nursery and had to try it. It is blooming beautiful and seems to like my little patio garden here in Bradenton, FL.

I love this plant and it's odd growing-blooming habit. Flowers are small and and beautiful. Scent varies from slight to none depending on the flower, nothing much here for anyone concerned with scent. This plant gets too much sun in my yard and the leaves burn easily, probably better in a shadier or dappled location, but even so, it still blooms like a champ.

As with the other Walking Iris's I LOVE this plant. The giant variety seems to be hardier here in St. Augustine FL and I have enjoyed its blooms the past few weeks! It's easy and a gorgeous statement in front of my front porch railing.
