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

Allium ursinum (ramsons) is a charming native allium, prized for its broad, fresh green leaves and neat, starry white flowers in spring. It is particularly well suited to lightly shaded corners and woodland-style planting, where it will naturalise beautifully and, in time, form handsome colonies.

For an elegant, relaxed effect, tuck the bulbs beneath deciduous trees or along the edge of a shady path, where the display can return with quiet reliability each year.

  • Colour & form: star-shaped white flowers over mid green foliage
  • Best for: woodland gardens, naturalising and ground cover
  • Garden value: pollinator friendly and pleasingly low-fuss

Where to Plant:

Allium 'Ursinum' (ramsons) needs 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 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!
