How to grow agapanthus

These dramatic sun-loving border plants produce large spherical flowerheads, usually in beautiful shades of blue, from midsummer onwards. These sway on tall stems above clumps of strappy foliage. Some types, especially the evergreens, may not be fully hardy, so are best grown in containers that can be protected from frost over winter
