Undoubtedly one of the most popular winter and spring shrubs, the bodacious blossoms of a camellia are a sight to behold. From October to May, these arresting, fully hardy specimens sparkle through our bleakest months. Camellias thrive in dappled shade and bring opulence, glamour and attractive scent to woodland or north-facing gardens. They require acidic well-drained soil, but if you don’t have these conditions, planting in containers is an option. Their lustrous evergreen form will provide year-round structure and interest, flowering or not. I have shortlisted three varieties of Camellia japonica with proven track records, all Royal Horticultural Society Award of Garden Merit (AGM) winners.
