How to grow aquilegias
Find out everything you need to know about planting, caring and propagating aquilegias in this detailed Grow Guide.
Aquilegias are traditional cottage garden plants, with delicate, nodding bell-shaped flowers and attractive foliage.
These reliable perennial plants, also known as columbine or granny’s bonnet, flower prolifically in May and June. With colours ranging from white through pale yellow to purples, blues and pinks, the flowers vary from singles to doubles and more unusual spurred varieties. Aquilegias make lovely cut flowers and the semi-evergreen foliage provides a good backdrop for other plants.
Take a look at our handy aquilegia grow guide, below.
Where to plant aquilegias
Aquilegias are woodland edge plants, so the best location is in partial shade in a fertile, moist but well-drained soil.
How to plant aquilegias
Dig over the soil, adding in leaf mould or garden compost, to improve drainage. Tease out the roots of pot-bound plants and firm into the planting hole, watering well.

Caring for aquilegias
Once your aquilegia plants are established, they need very little aftercare. For the best foliage display, cut back the summer growth in September for a late flush of new leaves that should last through the winter.
Cut flowering stems back after the blooms have faded, unless you want to collect the seed. Otherwise your chosen variety may become overcrowded with self-sown seedlings.
Aquilegias, like most perennials, will benefit from being lifted and divided every few years. This makes new, stronger plants and boosts their flowering potential.
Aquilegias will self-seed prolifically and cross-fertilise. You may end up with some unique variations in your own garden if you leave the plants to their own devices. Alternatively collect the seed by waiting till the pods have dried a little on the stem. Then cover with a paper bag and shake the dried seedheads to release the very tiny seeds.

Aquilegias: problem solving
Aquilegia downy mildew is a fungal disease particular to these plants. This can spread very quickly given the right conditions – cool and damp. Leaves will show spreading yellow patches that cause the leaf to curl and turn brown, with a white growth on the underside of the leaf. The flowers look distorted and stalks and seed pods can develop brown blotches. There is no remedy apart from removing affected plants and burning them.
