I haven't planted these yet, but if they do as well as last year's (Spring 2026), I'm certain they will be fine and beautiful next year.

As a gardener, I love to find flowers that have colors that you don’t see everyday. This checks the mark. Wonderful silver leaves and dramatic dark flowers. Excellent for both modern or traditional gardens
