Looking for a pop of late summer colour? Chrysanthemums are the perfect plant to add to your garden now when many other flowers are fading. They will bloom all the way through September and October, especially if you keep up with the deadheading. Easy to grow and low maintenance, chrysanthemums enjoy a warm, sheltered spot with fertile, well-drained soil. Good planting companions include other autumn-flowering border plants such as salvias, sedums and asters.
