How to Grow Columbine From Seed

Columbine is a perennial that rewards a little patience. The simplest approach is to sow in fall and let winter chill the seed naturally, so it sprouts in spring. You can also sow in early spring after giving the seed a cold-moist period in the fridge. As a perennial, columbine usually spends its first year making a leafy clump and then blooms the following late spring. In hot regions, sow so plants establish in the cool of spring or fall, and site them where they get afternoon shade.

Two things make or break columbine from seed: cold and light. The seed germinates best after a cold-moist spell, so either sow in fall or chill the seed in a damp paper towel or sand in the fridge for two to three weeks first. Then surface-sow, since columbine needs light to germinate, pressing the seed onto moist mix without covering it. Keep it cool and evenly moist; germination is slow and uneven, often 3 to 4 weeks. Transplant carefully, because columbine has a taproot, spacing plants 1 to 2 feet apart in well-drained soil in part shade to sun.

Columbine is low-maintenance once settled. Keep the soil evenly moist but never waterlogged, and go easy on feeding, since rich soil pushes leaves at the expense of flowers. Deadhead to tidy the plant and, if you like, to limit self-sowing, though many gardeners leave some seed to ripen so new plants replace the short-lived originals. If leaf miners leave white trails on the foliage, simply cut the plant back after bloom and it flushes clean new leaves.

Columbine suits other pollinator plants that tolerate cooler, partly shaded beds. These heirloom, non-GMO companions pair well with it:

Columbine is grown for its beauty rather than a harvest, but its nodding, spurred flowers make a lovely, airy cut flower. Snip stems in the cool of the morning when the blooms are freshly open for the longest vase life, and pair them with their own fern-like foliage for a delicate cottage arrangement. Leave some flowers on the plant to set seed if you want it to self-sow and keep coming back.

Columbine is a star of the part-shade garden, one of the few flowering perennials that thrives at a woodland edge or on the shady side of a border. Its nectar-rich, spurred flowers are a classic favorite of hummingbirds and are also worked by bees and butterflies. The delicate blooms and lacy foliage make an airy cut flower, and because it self-sows, it naturalizes into drifting, ever-changing colonies of color.

• Seeds won't germinate: they need cold stratification and light. Chill the seed, then surface-sow it and wait, since it is slow.
• White trails on leaves: leaf miners, mostly cosmetic. Remove affected leaves and cut the plant back after bloom for fresh growth.
• No flowers the first year: normal for this perennial; it usually blooms in its second spring.
• Flops or fades fast: columbine is short-lived, so let some plants self-sow to replace themselves over time.
• Poor bloom in rich soil: ease off fertilizer, which pushes foliage over flowers.
