Gardeners' Notes:


On Jun 25, 2014, SpringwoodGrdns from Penn Hills, PA wrote:

In zone 6, this plant will be normally be killed to 1-5" from the ground, but will still bloom reliably on old and new growth. It is also a rebloomer in ideal conditions. Produces some of the deepest blues I've seen. Blooms mature to "construction paper" gray. When killed to the ground, the plant only rebounds to a height of 12-18", so if you want to enjoy many stems and blooms, you're best served to overwinter this in a pot or container in northern areas so that previous year's growth is not killed.
