The Dahlia is a native perennial plant of Mexico related to sunflower, daisy, chrysanthemum, and zinnia.
Their striking blooms mean Dahlias are a great plant for creating an instant summer display mass planted in borders, or as feature plants on patios and in pots and containers. They make great cut flowers and gardeners often grow them in rows for flower arranging purposes.
Dahlias enjoy an open sunny position in the garden. In the cooler climate of the UK dahlias are not frost hardy and are often treated like an annual bedding plant. However, they can be overwintered in the ground in milder areas, or their tubers can be lifted from the ground in the autumn, stored in a frost free, dry place and then replanted in late spring, early summer.
