Cool down those hot summer days with a wash of chilled out blue Agapanthus umbellatus, also known as the African Lily. A real jewel of the summer garden, it bursts into bloom from midsummer onwards with dozens of tiny lavender blue trumpets on short spikes, gathered into a large ball of colour. These dreamy Agapanthus flowerheads are held on upright stems at a useful mid-height, perfect for planting in borders with smaller plants in front and taller plants behind.
