Aquilegia vulgaris var. stellata 'Nora Barlow' is a robust Hardy Herbaceous Perennial (H7). It represents one of the highest hardiness ratings in the British Isles, capable of withstanding temperatures below -20°C. While standard Aquilegias possess iconic nectar spurs, the stellata variety is spurless, featuring numerous pointed petals arranged in a rosette form that resembles a miniature dahlia or pom-pom.

The "Darwin" Heritage: This variety is a spontaneous mutation discovered and stabilized by Emma Nora Barlow, a prominent botanist and granddaughter of Charles Darwin. Its unique multi-layered architecture is a result of homeotic mutation where the spurs are replaced by additional petals, a trait that has been meticulously preserved since its formal introduction to the horticultural world.

Pollinator Haven: Despite its complex double-flower structure, 'Nora Barlow' is a high-value RHS Plant for Pollinators asset. Its open-facing rosettes provide accessible forage for emerging bumblebee queens and long-tongued bees during the critical late-spring window, supporting biodiversity in shaded garden areas.

Aquilegia seeds require specific light triggers and occasionally a cold period to break dormancy and ensure uniform germination.

How to Sow:
Sow indoors from January to May or in September. Surface sow the seeds onto moist, free-draining seed compost and do not cover them; Aquilegia seeds are photoblastic and require light to germinate. Press them gently into the surface to ensure contact. Maintain a temperature of 15-21°C. Germination is slow and erratic, typically occurring within 14-30 days, but can sometimes take up to 90 days.

The "Cold Trick":
If germination does not occur within 4 weeks, place the tray in a refrigerator (approx. 4°C) for 7-10 days. This cold stratification mimics winter and "unlocks" stubborn seeds. Return to warmth and light afterwards.

Where to Plant:
They thrive in partial shade or dappled sun and prefer humus-rich, moisture-retentive but well-drained soil. They are specialists of woodland edges and shaded borders. Space plants 30-40cm apart. While individual plants are short-lived (3-4 years), they will self-seed generously to create a permanent, wandering colony in your garden.

Ongoing Care:
After flowering finishes in June, the foliage can sometimes look tatty. You may cut the entire plant back to ground level; fresh, lush basal rosettes will re-emerge within weeks. For the best cut flowers, harvest stems when the first few blooms on the spike are fully open.

The raspberry-pink and green tones of 'Nora Barlow' pair spectacularly with available woodland partners from our range:

• 🌙 Sweet Rocket 'Purple': The Woodland Duo. Both species thrive in partial shade and flower simultaneously in May-June. The tall indigo spires of the Sweet Rocket provide a vertical backdrop for the pom-pom Aquilegia heads, creating a dreamy, highly fragrant spring display.
• 🦊 Foxgloves 'Excelsior Mix': The Height Layers. Create a professional woodland graduation by planting 'Nora Barlow' in front of tall Foxgloves. Both are hardy, self-seeding cottage classics that flourish in similar light conditions, providing a continuous wall of vertical colour for pollinators.

Surface sow in spring or autumn for a spectacular harvest of double raspberry pompoms that will return through self-seeding year after year.
