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.

Plant type: flowering

Watch for — Leaf miner: Columbine leaf miners leave white winding trails in the foliage. The harm is cosmetic; cut the leaves back hard after flowering and fresh, clean growth follows.

The reasons aquilegia 'nora barlow' isn't blooming

Almost every non-blooming aquilegia 'nora barlow' traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding aquilegia 'nora barlow' a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get aquilegia 'nora barlow' to flower

Maximise sun. Give aquilegia 'nora barlow' the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for aquilegia 'nora barlow' and get the feeding right with the aquilegia 'nora barlow' fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Aquilegia 'Nora Barlow' flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full aquilegia 'nora barlow' care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.
