Round-headed Leek

Allium sphaerocephalon

• Position: full sun
• Soil: fertile, well-drained soil
• Rate of growth: average
• Flowering period: July to August
• Hardiness: fully hardy
  
  Small, egg-shaped, claret-coloured flowerheads appear like drumsticks on tall, slender stems above strap-like, mid-green leaves in mid- to late summer. Planted en masse in a border in full sun, these diminutive claret flowers look great  emerging from a screen of foliage, or against a backdrop of ornamental grasses. They gently fade as summer comes to a close.
  
  
• Garden care: Split and divide large clumps in autumn or spring.
