Our "Bloom or Bust" Promise

Esculenta Quamash, often admired for its blue, purple colouring, is a bulb variety especially well suited to pots.

Camassia ‘Esculenta Quamash’ is a wonderfully graceful bulb for late spring, sending up refined spires of star-shaped violet-blue flowers above fresh, strap-like green foliage. It lends an effortless, natural air to meadow-style planting, relaxed borders, and lightly wild corners—particularly lovely woven through ornamental grasses and other naturalising favourites.

Dependable, fully hardy, and easy to grow, it settles in quickly and returns year after year, forming neat clumps that look increasingly assured with each season.

Why you’ll love it

  • Starry violet-blue blooms held on elegant, upright stems
  • Ideal for naturalising, informal drifts, and airy border planting
  • Pollinator friendly, with flowers that are welcome in spring gardens
  • Excellent structure for cutting gardens, with a poised, long-stemmed look

Planting notes

Plant in autumn for spring flowering. Choose a position in full sun or partial sun, in moist but well-drained loam. For a relaxed, meadow-like effect, plant in generous groups and allow the clumps to build over time.

Where to Plant:

Camassia 'Esculenta Quamash' (camas) needs full-sun, 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 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.

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!
