This is an unregistered seedling created by Peggy Jeffcoat and Catrina Matel (Catrina's Garden). I think it's very nice. Has proven fertile both ways here, and I think they should register it!
From Catrina's site: By Krentz-Matel 2000 - This is an unregistered seedling. The plant is interesting as it doubles about half of the time. The flowers are 5 inches and a rosey lavender with a mauve eye and yellow throat. Sometimes the double flower is a full pom pom like it’s parent Big Kiss, sometime a loose fringe and sometimes just a tuft. It’s pretty, with a lightly ruffled edge when not a double as well. When single you really notice the cream mid rib but if you look closely you see it in other forms as well. You will think you have different plants. A dormant diploid, this plant is happy at the front of the border, with a height of 20 inches. Parentage: Big Kiss x Lowcountry Lady
