Cactus Flowered Dahlias are a stunning seed-grown heirloom mix featuring slightly curved petals in a vibrant range of colors: alabaster, cherry, lemon chiffon, peach, and pink. These sturdy 3-foot plants produce magnificent blooms 5 to 6 inches across from summer through fall, reaching full flower in 84 to 98 days from seed. They thrive in full sun with moderate water, tolerate drought, attract pollinators, and resist deer browsing, making them equally valuable for cutting gardens or landscape color.

Seed-grown dahlias that reach 3 feet tall and produce 5- to 6-inch blooms in a stellar palette of pastel and warm tones. Unlike tuberous dahlias, these grow directly from seed started indoors 4 to 6 weeks before your last frost, flowering reliably within 84 to 98 days. They handle drought well once established, attract bees and butterflies, and the blooms make exceptional cut flowers that keep proliferating through November.
Cactus Flowered Dahlias excel in mixed borders and cutting gardens, where their long stems and substantial blooms shine in fresh arrangements. The flowers are prized by florists and home gardeners alike for their longevity in the vase and the way their slightly curved petals create depth and texture in bouquets. They serve equally well as focal points in landscape plantings, their sturdy 3-foot frames creating vertical interest throughout the summer and fall season.
No timeline data available yet for this variety.
Sow seeds indoors 4 to 6 weeks before your last spring frost date, maintaining soil temperatures of 70 to 75°F for germination. Seeds will sprout in 5 to 14 days depending on conditions. Sow at a depth of 1/8 inch, just barely covering the seed.
Harden off seedlings over 7 to 10 days by gradually exposing them to outdoor conditions. Transplant outdoors after all danger of frost has passed. Space plants 18 to 24 inches apart in prepared soil enriched with compost.
Direct sow seeds outdoors at the last frost date, planting at a depth of 1/8 inch and keeping soil moist until germination occurs.
Cut flowers for bouquets in early morning when the blooms are fully open and firm. Dahlias continue blooming through November in most regions, so harvest regularly to encourage more flowers. Cut stems at a 45-degree angle and remove lower foliage before placing in water.
Deadhead spent flowers regularly to promote continuous blooming throughout the season. Pinching back the central stem when plants are 12 inches tall will encourage bushier growth and more flower production.
