Double Mixed Columbine Seeds (Aquilegia) – Growing & Care Guide
Bring a romantic cottage-garden look to your yard with Double Mixed Columbines. These heirloom-style blooms feature extra layers of petals (double flowers) in a surprise mix of colors—pinks, purples, blues, whites, and bicolors. Perfect for borders, woodland edges, and pollinator gardens. Expect unique variation from plant to plant, just like a true “mixed” strain.
Germination & Sowing
Columbine seeds naturally prefer a cold period before they sprout. You have two easy ways to do this:
Fall sowing (easiest in most US zones)
Sow outdoors in late fall. Scatter seeds on loosened, well-drained soil, press them in gently, and barely cover—or don’t cover at all. Winter cold breaks dormancy and seedlings emerge in spring.
Indoor sowing for spring planting
Cold stratify first: place seeds in a bag with a small amount of barely damp seed-starting mix, seal, and refrigerate for 3–6 weeks. Then surface-sow in trays or pots. Do not bury deeply; light helps germination. Keep soil evenly moist and place in bright, indirect light at around 65–70°F (18–21°C). Germination usually takes 2–4+ weeks and can be uneven, so be patient.
Seedling Care
Once seedlings have true leaves, pot them up individually. Grow them on in bright light, keeping the mix lightly moist. When outdoor temps are stable, harden off for about a week and transplant after your last frost date.
Planting Out
Choose a spot with morning sun and afternoon shade for best results. Full sun is fine only where summers stay mild. Space plants about 10–15 inches apart. Soil should be rich in organic matter, moist but never soggy, and fast-draining. A little compost mixed in at planting time goes a long way.
Ongoing Care
Water regularly during the first season so roots establish well. After that, water during dry spells, letting the surface dry slightly between waterings. Columbines are light feeders—top-dress with compost in spring and avoid heavy nitrogen fertilizers, which can reduce flowering.
Blooming & Longevity
Plants grown from seed typically bloom in their second year, then return each spring/early summer. Columbines are short-lived perennials (often 3–5 years), but they readily self-seed. Deadhead spent flowers to extend bloom and limit reseeding, or leave a few seedheads if you’d like natural volunteers next season.
Good to Know
Because these are Double Mixed seeds, color and flower form will vary. Some plants may be semi-double or single, which is normal for mixed strains. Each plant is its own little surprise—part of the charm of growing columbines from seed.
