I’m a big fan of winter gardens that make the most of plants that look good when herbaceous borders are expanses of mulch-covered dirt. Trees with white trunks such as this Betula utilis var jacquemontii (Himalayan birch) often feature, together with evergreens, light-reflecting grasses, red stemmed Cornus (dogwood), Skimmia, Hamamelis (witch hazel), flowering heather, hellebores, Bergenia, Cyclamen and winter flowering bulbs.
Plants like this seem to shrug off winter weather, but the current cold spell means that the hardiness of plants of all types is being tested in many UK and American gardens.
Some gardeners go to great lengths to keep tender plants alive, wrapping their pots up, covering them with some form of plant blanket, or moving them indoors. Others will only plant what grows. Many of us are somewhere in-between, willing to offer our plant treasures a helping hand if conditions are unusually bad, provided we know what to do.
