Allium sphaerocephalon Flower Bulbs produce distinctive egg-shaped flower heads that mature from green to deep wine-red, creating changing colour through midsummer. Their slender stems weave beautifully through grasses and perennials.

Supplied as a pack of 50 bulbs, plants reach around 60-90cm (2-3ft) and flower from July to August. They are excellent for cutting and highly attractive to pollinators. Plant from September to November in free-draining soil in full sun.

Bulb size: 5/6
Bulb sizes are measured by circumference in centimetres. A 5/6 bulb measures approximately 5-6cm around. Larger bulbs generally contain more stored energy, helping to support strong growth and an impressive flowering display.

About our Bulbs
We work very closely with our growers to ensure we offer the very best, top sized bulbs which will provide you with a glorious autumn show. All of the bulbs we offer have been trialled and tested, either on our own trials ground, here in Suffolk, or on those of our growers, who we work with to ensure we offer the best range for British gardens.
