Dahlia variabilis. Dahlias are best started indoors 4 to 6 weeks before transplanting outside after all danger of frost has passed. Sow seeds in good seed-starting medium at 70°F with even moisture, strong light and good ventilation. Prepare bed in full to partial sunlight with rich, well-draining soil. Harden off the seedlings by gradually acclimating them to outside conditions for 1 to 2 weeks prior to transplanting outside. Dahlias are moisture-loving plants. Mulch to conserve moisture, water consistently and fertilize as necessary. When the first frost kills the stems and leaves, dig up the tubers and store them in slightly dampened peat moss at 45° to 55°F over the winter. Good cutting flowers, The Collarette Mixture includes white, red, scarlet and yellow Dahlias. Summer flowering. Height: 30" to 39".
