25 Rock Star Dahlia Seeds - Perennial Flower Seeds for Planting

Rock Star Dahlia is a striking perennial flower known for its bold, star-shaped blooms that add dramatic color to garden beds and borders. These seeds produce plants that typically grow 2 to 3 feet tall, making them suitable for mid-border plantings or large containers. The flowers are attractive to pollinators and make excellent cut flowers for fresh arrangements.

Planting & Care

Sow Rock Star Dahlia seeds indoors 6-8 weeks before the last frost date. Use a well-draining seed-starting mix and barely cover the seeds with soil, as light aids germination. Keep the medium consistently moist but not waterlogged, and maintain a temperature of 65-75°F. Once seedlings have two sets of true leaves, transplant them into individual pots and harden them off gradually before moving outdoors after the danger of frost has passed.

Plant dahlias in full sun with well-drained soil. Water regularly, especially during dry spells, but avoid overwatering to prevent tuber rot. Pinch back the growing tips when plants are about 12 inches tall to encourage bushier growth and more blooms. Deadhead spent flowers to prolong the blooming season. In colder zones, dig up tubers in fall after the first frost and store them in a cool, dry place for replanting next spring.
