Dahlia Decorative ‘Crème de Cassis’ (1 tuber/pkg)

Dahlias are extremely showy in the summer garden.  This Decorative Dahlia produces elegant flowers of lilac purple, with deep plum undersides. Grows up to 40″ tall.

Plant tubers in spring, after risk of frost has passed. Dahlias need full sun, and prefer a soil that’s amended with organic matter, like compost. Plants get big and need support, so hammer a stake into the ground when planting to tie to as it grows. Blooms will begin in midsummer and continue through Fall. Feed with a blooming plant food every 3-4 weeks for best flowers. After frost has killed the top growth in Fall, dig up tubers and store for the winter. Tubers multiply into a clump throughout the growing season. You’ll find you have more dahlias to plant next year!
