Our local dahlia production is limited during the winter months. The season starts for most colors May/June through late October/early November and we encourage advance orders. Black dahlias are grown outdoors. The color tones of certain varieties may vary from the photos. Bunches come with 5 stems each. Vase life is 3 to 5 days. Dahlias are delicate and usually have one main bloom with multiple bud laterals. The stem length on most dahlias are 20-25″. Bloom size varies from 2.5-5″ in diameter.
