How to Grow Columbine 'Nora Barlow'

Tiny seeds sprout with first true leaves emerging. Requires cold stratification (4-6 weeks) for better germination rates.

Keep soil moist and cool. Light stimulates germination. Provide 60-70°F temperatures. Germination takes 14-21 days.

First year plants develop a rosette of ferny foliage. Leaves are deeply lobed and finely textured, blue-green in color.

Thin seedlings to proper spacing. Keep consistently moist. Provide bright, indirect light. No fertilizer needed yet.

Plant builds stronger root system and increases foliage. Many cultivars require two years before flowering. Foliage mound grows 12-18 inches tall.

Water regularly. Apply balanced fertilizer in spring. Mulch lightly to retain moisture. Deadhead any flower buds first year to encourage establishment.

Tall flower stems (24-36 inches) emerge in late spring to early summer. Double pompom-like flowers with layered pink, white, and purple petals appear along stems. Blooms lack typical spurs.

Support tall stems with stakes if needed. Deadhead spent flowers to encourage more blooms. Water at soil level to avoid wetting flowers. Provide afternoon shade in hot climates.

Flowers fade and develop seed pods if not deadheaded. Foliage begins to yellow and decline in summer heat.

Allow some flowers to set seed for self-sowing. Cut back declining foliage in summer for neatness. Reduce watering as plant goes dormant.
