Allium Purple Sensation Bulbs produce rounded heads of rich purple star-shaped flowers on tall, sturdy stems. Their bold architectural form makes them one of the most versatile ornamental alliums for threading through borders.

Supplied as a pack of 15 bulbs, plants reach around 90cm (3ft) and flower from May to June. They are excellent for cutting and highly attractive to pollinators. Plant from September to November in free-draining soil in full sun.

Bulb size: 12+
Bulb sizes are measured by circumference in centimetres. A 12+ bulb measures at least 12cm around. Larger bulbs generally contain more stored energy, helping to support strong growth and an impressive flowering display.

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.
