PERENNIAL GROWN AS ANNUAL
Frost tender.
Summer/fall bloom.
BEST TO START EARLY INDOORS
Sow seeds 2 inches apart in containers of seed starting mix, 4 to 6 weeks before last spring frost. Cover ½ inch deep, keep moist and warm and provide a strong light source until ready to plant outdoors. When weather is warm and settled, acclimate seedlings gradually to outdoor conditions. Plant 16-18 inches apart in full sun.
TO START DIRECTLY OUTDOORS
Wait until weather is warm and settled and night temperatures are above 50°F (10°C). Sow groups of 2 to 3 seeds ½ inch deep and 16-18 inches apart in well-worked, fertile soil in full sun. Cover lightly and keep soil moist but not soggy while awaiting germination. When well-established, thin carefully to one single seedling 16-18 inches apart, so plants have room to grow. Keep evenly watered.
GROWING NOTES
Encourage growth and bloom by feeding monthly with a liquid, all-purpose fertilizer. Deadhead to prolong bloom. These dahlias will produce underground tubers after their first season.
In mild winter climates: Tubers can overwinter in the ground. In cold winter climates: Dig up the tubers in late fall to replant next spring.
Plants grow 4-5 feet tall with branching stems of big, colorful, star-like blossoms to enjoy in casual bouquets. These vigorous plants will bloom all season long.
