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

Allium cristophii (Star of Persia) brings a composed sense of theatre to the late spring garden. Each stem carries a broad, shimmering head of rosy‑violet, star-shaped flowers—architectural without being overbearing, and particularly handsome rising through fresh greens at the front of a border.

As the colour softens, the seedheads remain beautifully sculptural, lending quiet structure well into summer. A natural choice for gravel gardens and contemporary planting schemes, and a superb subject for cutting and drying.

  • Large, starry flower heads in May–June
  • Excellent for cut flowers and long-lasting dried arrangements
  • Pollinator friendly and notably deer resistant
  • Fully hardy perennial—returns with increasing presence over time

Where to Plant:

Allium 'Christophii' (Star of Persia) 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 15-20cm 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!
