The Dahlia Bishop of Canterbury flowers from July to the first Autumn frosts. That is often the end of October and even into November. The bright cerise red flowers are produced repeatedly all summer. Just keep picking to produce more flowers.
You could have vases full of Dahlias all summer.
Dahlia Bishop of Canterbury grows up to 36″ (90cm) and is ideal for brightening a dull green summer border or in a perennial border.
Dahlias originate in Mexico and thus won’t survive our cold winters. The tubers should be lifted after the first frosts and stored in paper bags in a frost free building until late winter early spring.
