Dahlias are a tender perennial (in most areas annuals) that are vigorous and fast growing. They are an outstanding addition to the flower border or container garden. Attracting hummingbirds and butterflies, Dahlias are an old-fashioned favorite. Flowers bloom first year and add a lovely spot of color in the garden. They thrive when the temperatures climb, and they will be profuse bloomers until the first frost. Sow Dahlia seeds indoors 4 - 6 weeks before the last frost. Lightly cover the Dahlia flower seeds with soil or peat moss only the thickness of the seed itself. Transplant seedlings outdoors after danger of frost has passed.
