Allium Unifolium

Also known as one leaf onion this allium is known for its delicate clusters of star-shaped, pinkish-lilac flowers, with multiple flowers per stem they bloom in loose clusters above green basal leaves. Thriving in sunny or partially shaded areas and well drained soil with a height of 30cm, this makes them a perfect choice for borders or containers and is a perfect addition to any spring garden.

Planting Instructions

When to Plant:

Plant bulbs in autumn (September to November), before the ground freezes.

Where to Plant:
Choose a sunny or partially shaded spot with well-drained soil. Ideal for borders, rockeries, or containers. Allium unifolium prefers soil that does not remain waterlogged over winter.

How to Plant:

• Depth: Plant bulbs 8–10cm (3–4 inches) deep.
• Spacing: Space bulbs 10–15cm (4–6 inches) apart.
• Position: Place the pointed end facing upwards.

Aftercare:
Water well after planting. Once established, they need minimal care. Allow the foliage to die back naturally after flowering to feed the bulb for next year’s growth. Bulbs can be left undisturbed to multiply over time.
