A single twenty degree night changes the garden. A day before, coneflowers (below), azaleas, camellias (2nd photo, below), and toad lilies were flowering despite repeated frosts and a light freeze a few weeks ago. After this freeze, flowers remain, but in an altered state that shows effects of the cold.
While some extol the beauties of seedheads and browned grasses, I prefer leaves and flowers to the dormancy of winter. The silhouettes of Japanese maples (below), and particularly of Harry Lauder’s walking stick (Corylus avellana ‘Contorta’), can be quite marvelous, and colorful berries attract bluejays and cardinals, but these are small consolation.
Though damaged blooms will not recover, unopened buds of camellias (below) will continue to flower for at least another month, and there could be additional blooms on Encore azaleas. Flowers of ‘Eternal Fragrance’ daphne are slightly damaged in the cold, but there are likely to be more blooms if mild temperatures return.
Flowers of hybrid mahonias are not damaged by cold. ‘Winter Sun’ (Mahonia x media ‘Winter Sun’, above) began flowering several weeks ago, and ‘Charity’, ‘Underway’, and the newly planted ‘Marvel’ (below) will follow and are likely to flower through repeated spells of cold into the new year.
