Plant allium bulbs from September to December. If needed, keep them in their open packets somewhere cool, dry and well ventilated until planting.

The zingy green-ish yellow flower clusters of Allium obliquum add a cool zestiness to planting schemes during mid-summer, which is perfect for bringing an air of cool to the garden when the mercury is peaking. Any style of garden should include a hint of quirkiness, and with its vivid greenish yellow ball-like flower heads sat above unusual twisty stems, this allium would happily fill that role. As with all alliums, this one makes a great cut flower. Plant plenty and enjoy them in your home too! They have a very long vase life and look particularly good in a mixed bunch.
Allium obliquum is very versatile – combine it with mixed flowers in contrasting bright colours to create an eye-popping funky look, plant it in swathes among shrubs for a sleek toned-down look, or add it to a cottage-style mixed flower border to provide contrasting structure – in fact, it’s fair to say that this allium would look great anywhere!

Plant profile
Plant calendar
Choose full sun or partial shade. Improve heavy soil with organic matter and horticultural grit. For containers, use peat-free multipurpose compost with good drainage.
Plant bulbs pointed side upwards, two to three times their own height deep. A slightly flattened side is perfectly normal and nothing to worry about.
Space small bulbs around 5cm apart. Larger bulbs need more room, generally around twice their own width apart, so their foliage and flowers can develop freely.
Water after planting if the soil is dry, then only when needed. After flowering, allow the foliage to die back naturally. Decorative seedheads can remain in place.
