Looking for Dark Blue or Violet Hydrangea
I have a couple of ENDLESS SUMMER hydrangeas and I love them but I'd like to expand the color range among my shrubs. For me ES blooms in a clear sky blue or pastel pink. I'm looking for something darker to provide contrast. I read an article written by Richard Bir and J.L. Conner on reblooming bigleaf hydrangeas and two cultivars have attracted my interest for deep color, medium growth habit and ability to rebloom.
These are ALTONA and MARECHAL FOCH.
Are they good hydrangeas? I'd like to read your comments before I place my orders.
I'm also interested in NACHTIGALL (Nightengale), a beautiful Lacecap known for its deep indigo flowers.
