Here is a plant which has made a swift rise to fame over the past couple of decades. Everyone who is everyone seems to grow alliums, they are a staple of every stately home and on every gardener's wish list.

One of the originals and a classic for a first-time allium grower, is the Allium 'Purple Sensation' blub - the ornamental alliums deep rich purple balls offering a strong silhouette. Alliums burst onto the scene in May and June and fill your early borders with structure and sophistication.

For over-sized flower heads of ostentatious proportions, 'Giganteum' is a real show-stopper. The flowers resemble footballs, and as with all alliums, their dried seed heads after flowering are equally as valuable and beautiful when left in the border or taken inside and displayed as dried flowers. Alliums also make excellent cut flowers.

Whites have become increasingly popular and 'Mount Everest' is a perfect performer. A stunner in a white border scheme. The epitome of elegance when planted amongst other whites and greens - perhaps surrounded by box (Buxus) hedging.

If you like the unusual, there are plenty of options available to offer a twist away from the classic balls of beauty. 'Hair' displays a crazy green tangle of fun - while 'Nectaroscordum siculum' bares umbels of creamy, green lilac flowers - a real talking point.

When to plant Allium bulbs

Plant alliums in early to mid-autumn at a depth of about 3 to 4 times the height of the bulb and fill your borders with en vogue elegance.

Where to Plant Allium bulbs

All alliums work well in a prairie-style design, planted amongst grasses. Their love of dry sunny spots and good drainage also makes them a perfect gravel garden candidate.
