Dahlia: A Field Guide
Dahlias get all the attention. Don’t fight it. With flowers that range in shape from dinner plates to powder puffs and bloom in gemstone hues of red, pink, orange, yellow, and purple, dahlias were born for center stage.
Discovered by early Spanish explorers in warm South American climes, dahlias will not survive cold winters. Dig up tubers and store them in straw in a cellar or garage; replant after the last frost date. Does this sound like too much trouble? If so, you have not looked closely enough at a dahlia. Among Dahlia’s 42 species and countless cultivars, some favorites: ruffly purple and white ‘Edinburgh’; spiky golden ‘Glorie of Noordwijk’, and velvety dark red ‘Chat Noir’. Plus a hundred others.
