This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

• Position: full sun
• Soil: fertile, well-drained soil
• Rate of growth: average
• Flowering period: June
• Hardiness: fully hardy
• Allium bulb size: 18/20


This allium forms generous clumps of mid-green leaves, which start to die back before the sturdy, upright stems emerge in early summer, bearing large rounded flower heads. The lavender-purple flowers of 'Gladiator' blend well with most shades of pink, as well as stronger purples and plums.


• Garden care: Bulbs can be planted 15cm deep and 15cm apart. Pot-grown plants can be enjoyed as they are while in bloom, but as the flowers fade, they should either be potted up or planted out in the garden. Avoid excessive mositure when the plants become dormant (from late summer) and lift and divide over-large clumps in autumn or spring.
