Our "Bloom or Bust" Promise

Large Flowering Mix, often admired for its purple, white colouring, is a bulb variety especially well suited to pots & containers.

Allium 'Large Flowering Mix' is a generous selection of large-flowered ornamental onions, chosen for their poised, globe-shaped heads and a softly varied palette. Rising above fresh grey-green foliage, the blooms bring elegant structure from late spring into early summer—particularly effective threaded through borders, gravel gardens, or grouped in generous drifts for a naturalistic finish.

These fully hardy bulbs are wonderfully uncomplicated: plant in autumn, allow them to settle over their first seasons, and enjoy their refined, architectural presence year after year. They are also excellent for cutting—bringing a calm, contemporary note to arrangements.

Where to Plant:

Allium 'Large Flowering Mix' needs full-sun, partial 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 20–25cm 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!
