Our "Bloom or Bust" Promise

Summer Drummer, often admired for its purple, white colouring, is a bulb variety especially well suited to borders.

Allium 'Summer Drummer' is the sort of perennial that lends a garden instant composure. Towering stems carry tightly packed, spherical flowerheads in pale purple with lighter highlights, rising well above neighbouring planting for a clean, architectural finish in high summer.

Plant the generous bulbs in autumn and allow them to settle in; by their second season they begin to make a handsome, long-legged statement—ideal threaded through borders, cottage-style planting, or neatly designed city courtyards. The blooms are also excellent for cutting, bringing height and poise to arrangements.

  • Bulb size: 18/20
  • Habit: Clump-forming perennial with tall, upright stems
  • Flowering: July–August
  • Best for: Borders, cottage gardens, city & courtyard gardens, cut flowers

Where to Plant:

Allium 'Summer Drummer' needs full-sun and a warm, sheltered position for the best flowering. Plant into fertile, humus-rich soil that drains well, and choose a spot protected from strong winds, especially for taller varieties.

How to Plant:

Plant bulb from September to December once conditions are suitable. Set them at the correct depth for the variety, spacing 20-30cm apart where relevant, then firm in gently and water well after planting.

Aftercare:

Water regularly in dry weather and feed every two to three weeks once buds appear. Stake taller stems early and deadhead to keep plants flowering. After flowering, allow foliage to die back naturally before lifting or protecting bulb according to local conditions.

I ordered the mixed hyacinth collection and the scent in my garden this April was absolutely heavenly. Every single bulb produced a strong, beautiful flower and the colours were stunning together. A fantastic purchase, I'll be back for more next year!
