Our "Bloom or Bust" Promise

Roseum, often admired for its soft pink and white colouring, is a bulb variety especially well suited to borders.

Allium ‘Roseum’ is a charming, lightly naturalistic allium, carrying loose heads of soft pink, cup-shaped flowers above narrow, grassy foliage. It’s a wonderfully simple way to weave gentle colour through late spring and into early summer—particularly handsome when planted in drifts through borders or tucked into containers for a relaxed, cottage-garden finish.

  • Flower colour: soft pink and white
  • Height: 60cm
  • Habit: clump-forming perennial
  • Best in: borders, containers, and as a delicate cut flower

With its refined, airy presence, this is a lovely companion to late tulips and fresh spring greens, and it’s also welcome in wildlife-friendly planting schemes.

Where to Plant:

Allium 'Roseum' (Rosy-flowered 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 10cm 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!
