Gardeners' Notes:

Positive msbobolink On May 9, 2006, msbobolink from Tompkinsville, KY wrote:

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.
