I bought three fans of this beautiful iris last fall and planted them "temporarily" in a large box of dirt, but they ended up wintering over in that box. We had a very mild winter and they did really well in their temporary location. All three of the fans are flowering this year, unlike some of the other varieties that I bought at the same time and over-wintered in the same way.

Does anyone know if this is an easy one to get started and established? I love the colors but don't know if I should get it or not, (zone 5).
