THE MONTH AHEAD
There are early, mid-season and late flowering Rhodos. The first to bloom during winter are Sir Robert Peel, Sir John Waterer, Mrs Henry Shillson and Christmas Cheer. These are followed by Cornubia, Red Admiral and Chevalier Felix du Sauvage. These early varieties can have their blooms damaged by rain or hail, but they do not suffer from petal blight.
