About Aquilegia 'Nora Barlow'

Aquilegia vulgaris 'Nora Barlow' · also called Nora Barlow columbine, double columbine · flowering

Aquilegia vulgaris 'Nora Barlow' is a heritage double columbine with quirky, spurless pompom flowers of pink-red petals tipped in green and white, held on tall stems over ferny blue-green foliage in late spring. A robust cottage-garden favourite, it thrives in sun or part shade and moist, well-drained soil, and self-seeds enthusiastically.

Preferred mix: Fertile, moist, well-drained loam, neutral to slightly acidic or alkaline

Watch for — Powdery mildew: White mildew can coat stressed plants in dry, crowded conditions. Shear spent foliage after bloom, water at soil level, and give plants room for air movement.

Why aquilegia 'nora barlow' needs this mix

Aquilegia 'Nora Barlow' flowers hardest in a rich but free-draining loam — fed enough to fuel the display, open enough that the roots never waterlog.

What goes wrong with the wrong mix

Either starving aquilegia 'nora barlow' in a thin mix or drowning it in a heavy, badly drained one. It wants the rich-but-free-draining middle, plus a flowering (higher-potassium) feed in season.

pH — does it matter for aquilegia 'nora barlow'?

Most flowering plants, including aquilegia 'nora barlow', do well around pH 6.0-7.0. A cheap soil test is worth it outdoors; one notable exception is any acid-lover (such as some hydrangeas), where pH directly changes flower colour.

If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.

DIY mix vs a bagged one

A quality bagged compost works for aquilegia 'nora barlow' in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.

Drainage and the pot

Free drainage protects the roots and especially the crown over winter — raised beds, grit in the planting hole and never a waterlogged spot. Containers must have a clear drainage hole.

For perennials, refresh the top layer and feed each spring rather than disturbing the roots; for container displays, start with fresh rich mix each season. When the time comes, our repotting guide for aquilegia 'nora barlow' covers the timing and technique step by step.
