Gardener Favourites: Alliums

Allium Violet Beauty

Allium Violet Beauty

The striking, showy flower heads of the humble Allium have long been a favourite of the modern cottage gardener. Blending beautifully into a summer perennial border, tall statuesque Alliums will cheerfully tower above lower growing plants just a seamlessly as smaller Alliums will add a zing to the front of a low border or edge.

Easy to grow and versatile enough to be able to be grown in borders, flower beds, patio pots and containers, where they really will pack a punch. A must have impact plant for spring and summer.

Beyond the garden Allium flowers and seed pods are excellent additions to cut flower displays. If you’re feeling creative they can be dried and sprayed to use as festive decorations.

Not just a pretty flower…

Also known as Ornamental Onions, Alliums are from the onion family and are a fantastic addition to any garden. They are great for deterring Aphids, protecting other plants in your garden as well as themselves making them excellent companion plants.

Loved by bees…

Over the last few years we’ve been running a Spring flowering Bulb Competition (see details for this years competition here) and as these past entries show, (above) Alliums are highly attractive to bees! Great for the wildlife friendly gardener.

Planting

POTM January Alliums

For the best results position in full sun, and in well drained soils. For poorer soils treat with potash feed in the spring, which will help all your spring flowering bulbs and encourage them to return the following year.

Plant from early autumn at three or four times their own depth. The gaps you leave between Alliums will depend on their mature size, as well as your overall design ideas! For smaller Alliums plant 10cm apart, the larger varieties will need at least 25cm in between. We indicate planting depths/distance for individual varieties on their own product pages.

Most Alliums will do well in containers as long as you give them enough space. They need a good 4cm of compost beneath each bulb, so choose deep pots, and for soil use any multipurpose compost, such as John Innes No 3. Some prefer to mix equal parts soil to horticultural grit. Re-pot each autumn.

This spectacular mixture of medium and tall Alliums varying in shades of creamy white, pink, mauve to the deepest purple-violet to create an amazing firework like display in your summer garden.

Those beautiful leaves…..when they’re no longer beautiful!

One of the most striking features of Alliums is the long, sturdy stems that keep those amazing pom-pom like balls of flowers suspended on high. From the base of the Alliums grows lush, lance like swords of green foliage. As the flowers fade the basal foliage will wilt and turn brown. Unsightly as it is, don’t try to remove the leaves until they have all completely died off or you will stop the bulb taking enough food for winter to ensure it comes back the following year. If you are including Alliums in your flower bed and border design it’s a good idea to ensure to surround them with low growing plants that flourish in late summer to screen the foliage as it browns. Lavender likes similar conditions to Alliums or Hardy Geraniums will come in after the Alliums and continue to the end of summer.

 Unusual Alliums

Thanks to their increasing popularity, Allium varieties such as Purple Sensation, the huge Globemaster variety, and Spharocephalon – more commonly known as The Drumstick Allium – have become staples for many gardeners.

  1. I bought Papaver Giant King Kong last July, 3 for £9.98.

    As they were bare rooted with little sign of growth when I received them I potted them on and put them on my vegetable beds where they were kept well watered.
    I planted them out earlier this year in there final planting positions. One of them has just flowered, it is very pale pink/white and 40cms tall. This is not what I expected or wanted having ordered the Giant King Kong which is tall and red. I wanted them for a specific position for the height and the outstanding colour.
    I look forward to your comment
