Ampeloprasum, often admired for its pale pink-lilac and white colouring, is a bulb variety especially well suited to borders.

Allium ampeloprasum is a wonderfully statuesque allium, prized for its papery buds opening into rounded, lilac-toned globes held aloft on tall, steady stems. Rising cleanly above broad, grey-green foliage, it brings an assured sense of height and structure from late spring into early summer—particularly handsome woven through mixed borders and naturalistic planting.

It also makes a refined cut flower: allow a few stems to open fully for a soft, architectural note indoors, while leaving plenty in the garden for visiting pollinators.

  • Elegant, architectural flowerheads in pale pink-lilac and white
  • Excellent height for adding lift through borders and meadow-style schemes
  • Pollinator friendly and deer resistant
  • Fully hardy and pleasingly low-fuss in well-drained ground

Supplied as autumn-planting bulbs.

Where to Plant:

Allium 'Ampeloprasum' 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 20cm 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.

The bulbs arrived beautifully packaged and you could just tell they were excellent quality. We had the most wonderful display of daffodils this spring on our patio. Simply stunning. Will definitely be ordering again

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!
