I live in zone 9b-10 and I have had wonderful success with this hydrangea. It is the first and only one I've ever grown. No insect damage, lots of new growth from center, clean leaves. I used a product to make them turn blue--very beautiful. I grew this plant from a gallon size and this is the end of the second year.

Information from both "Hydrangeas for American Gardens," by Michael A. Dirr (2004) and "Encyclopedia of Hydrangeas" C.J. and D.M. Van Gelderen (2004 - Timber Press). Bred by Penny McHenry and introduced by Louisiana Nurseries, U.S. Strong grower to 5'-6' tall. One of the more frost hardy varieties. Flat medium green leaves, flowers pink to mid blue, age to tones of rose to aquamarine. Flowers on this seasons growth so a good pick for northern gardens.
