Bloom or Bust Guarantee

Neapolitanum, often admired for its white colouring, is a bulb variety especially well suited to containers.

Allium neapolitanum is a smaller, exquisitely poised allium, prized for its crisp white, star-shaped blooms gathered into neat umbels. Held on slender stems above fresh mid-green foliage, it brings a clean, luminous note to gravel planting, sun-baked edges and beautifully finished pots.

Particularly useful where winter wet makes heavier ground unreliable, this is a quietly confident choice for raised beds and containers—easy to place, and all the more elegant when planted in generous drifts.

  • Flower colour: White
  • Form: Star-shaped umbels on neat stems
  • Ideal for: Containers, gravel gardens, courtyards and borders

Where to Plant:

Allium 'Neapolitanum' (Neapolitan garlic) 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 10-15cm 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!
