Masses of blooms on towering plants. Tall arching stems bear an abundance of large double blooms. These towering giants create breath taking displays in Autumn and Winter when the rest of the garden is bare. Grow against a wall or fence.

How To Grow
Prepare the soil by adding organic matter and compost. Dig in some blood and bone prior to planting. Plant in a moist well drained soil, protected from wind – ideal position is against a wall or a fence. Provide a stake before planting and tie the plant as it grows. Dahlias tolerate morning or afternoon shade. The long flowering period lasts from Autumn into Winter.
