Giant Hybrid Mix Dahlia Seed

Item #HSC-DAH-001-PKT

Big, bright dahlias from seed.

Growing dahlias from seed is an easy, budget-friendly alternative to buying tubers. Seed sprouts readily and plants grow quickly, flowering from mid-summer until hard frost.

Blooms are 3–5" across, in double, semi-double and single forms, in solids and bicolors of salmon, coral, white, pale yellow, red and lavender. Seed-grown doubles are usually less full than named tuber-grown varieties. The mild petals make a colorful garnish for salads, desserts and drinks.

Flowers about 75–90 days from sowing, on plants 40–60" tall. Open-pollinated.

Specs

  • Packet: 50 seeds
  • Average 3,100 seeds per oz.
  • Plant height: 40–60"

Growing Information

Days to germination

About 3–5 days, held at 65–70°F (18–21°C).

Starting indoors

Recommended. Sow 4–5 weeks before your last frost, cover, and keep the surface moist until seedlings show. Move up to larger cells at the true leaves, handling roots gently and never letting them get rootbound.

Direct sowing

After frost, once soil is 65–70°F: about 2 seeds per foot, 1/4" deep, firmed in. Keep moist and thin to 9–12".

Plant spacing

9–12".

Light

Full sun.

Harvest

Cut before the blooms are fully open.

Saving tubers

Seed-grown plants form tubers you can keep. After frost blackens the tops but before the ground freezes, cut back to 2–4", dig carefully and knock off soil. Cure 1–3 days somewhere warm, airy and shaded, then store in peat or vermiculite in vented bags or crates; replant next spring.

Hardiness

Grown as an annual.

Plant height

40–60".

Scientific name

Dahlia variabilis
