Dahlias are loved for their long flowering season, which often lasts until the first frosts, and come in a huge variety of flower colour and shapes. Grow them as part of a late-summer planting scheme or as a cut flower.
How to grow dahlias
Dahlias require a fertile, moist but well-drained soil, and a sunny, sheltered spot. Taller varieties need staking. In autumn, dig up the tubers and overwinter them in a frost-free place such as a greenhouse or a shed. Plant them back in the ground from May onwards.
