Plant allium bulbs from September to December. If needed, keep them in their open packets somewhere cool, dry and well ventilated until planting.
Comprising Allium 'Gladiator' and Allium 'Mount Everest', this spot-on collection is a ready-made showpiece that will bring structure and style to the garden during late spring and early summer. Both of these giant varieties are stately and impressive in size, growing to a height of over 1m and with big round flower heads that sit together to make vibrant balls of colour. This lovely pair make for real eye-candy when planted together in sunny borders, turning the colour volume up to the max just as the garden’s gearing up for summer.
Alliums are fully hardy and very easy and reliable to grow. Plant the bulbs in autumn and then all you have to do is wait for a show-stopping display which will return every year. These generous plants provide high-impact looks when planted in groups in the border, but can also be dotted around in mixed beds to make bobbing spotlights. This tall variety brings height to planting schemes whilst taking up very little foot-space, which makes them particularly useful for narrow borders or large containers. If you like cutting flowers from the garden to use in indoor arrangements, these are the perfect contemporary choice for late-spring displays.

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.
