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

Allium 'Ambassador' is a quietly dramatic choice for early-summer structure—generous, rich purple flower globes held aloft on tall stems, rising elegantly above neat green foliage. Planted in autumn, it returns as a reliable perennial, lending height and poise to borders and looking particularly accomplished weaving through perennials and ornamental grasses.

  • Colour & form: rich purple, perfectly rounded globe heads
  • Where it excels: borders, pots and containers, naturalising, and cutting for the vase
  • Garden allies: pollinator friendly and noted as deer resistant
  • Planting season: autumn planting for flowers in early summer

Choose a sunny, well-drained position and allow space for those impressive stems to stand with confidence. Whether dotted through a mixed border or repeated in a considered drift, 'Ambassador' delivers a refined, architectural finish just when the garden begins to gather pace.

Where to Plant:

Allium 'Ambassador' 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 25–30cm 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.

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!
