Our "Bloom or Bust" Promise

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

Allium cernuum (lady’s leek) brings a pleasing note of refinement to early-summer borders: slim stems topped with gently nodding, bell-shaped umbels in deep pink, held neatly above fresh green foliage. It is particularly elegant when threaded through grasses and perennials, and it looks equally at home in gravel planting or a well-dressed container.

Fully hardy and admirably undemanding, this clump-forming allium is also a fine choice for pollinator-friendly schemes, offering nectar-rich flowers through the summer months.

  • Colour & form: deep pink, bell-shaped umbels with a graceful nod
  • Garden use: borders, gravel gardens and smart containers
  • Wildlife value: pollinator friendly
  • Practical bonus: deer resistant

Where to Plant:

Allium 'Cernuum' (lady's leek) 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!
