Description
Add dramatic structure and vibrant colour to your garden with these Ornamental Onion (Allium) bulbs, supplied in a handy Pack of 3. Known for their tall stems topped with perfectly rounded flower heads, ornamental onions bring architectural beauty and pollinator-friendly blooms to borders, beds, and containers.
From late spring into early summer, they produce large, spherical clusters of starry purple or lilac flowers, creating a stunning focal point that contrasts beautifully with softer perennials and grasses. Long-lasting both in the garden and as cut or dried flowers, alliums are reliable, low-maintenance, and a true sign of the summer garden’s arrival.
– Perfectly round flower heads in rich shades of purple and lilac.
– Loved by bees, butterflies, and other beneficial insects.
– Hardy bulbs that return year after year with minimal care.
– Ideal for borders, gravel gardens, or pots.
– Excellent for cutting or drying, extending enjoyment beyond flowering season.
Position: Full sun for best flowering; thrives in open, well-drained spots.
Soil: Well-drained soil, ideally sandy or loamy; avoid heavy, wet ground.
Planting Depth: Plant bulbs 3 times their own depth and 10–15cm apart.
Watering: Water after planting and during dry periods until established.
Feeding: Apply a balanced fertiliser in spring as shoots emerge.
Aftercare: Allow foliage to die back naturally to nourish the bulbs for next year.
Q: When do ornamental onions flower?
A: Typically from May to July, depending on the variety and conditions.
Q: Can I grow them in pots?
A: Yes – they grow beautifully in deep containers with good drainage.
Q: Will they come back each year?
