Will Agapanthus Kingston Lily survive the winter. I live on the Sussex coast, my garden is sheltered but doesn’t have a greenhouse. Thank you
As a deciduous variety they are generally more cold hardy. They should be cut back after the leaves have died back naturally. They can be covered with a fleece or cloth to protect them from very cold extremes
