    A gorgeous allium with small, egg-shaped flowerheads, that top tall, slender stems in mid- to late summer. Planted en-masse in a border, these diminutive claret-coloured flowers look great emerging from a screen of foliage, or against a backdrop of ornamental grasses. They gently fade as summer comes to a close.

  • Garden care: For best effect plant the bulbs 8cm deep in natural drifts. Avoid soils that are too wet, and split and divide large clumps in autumn or spring.

  • CAUTION do not eat ornamental bulbs

Notes on Allium sphaerocephalon

"The classy drumstick allium - slender and upright with a tight head of summer-green buds maturing to maroon - before fading to parchment in late-summer sun."

Extremely easy to grow


Plenty of flowers but a bit leggy and needed support so I planted some annuals in between. Hopeful for a better display next year.




I wouldn't buy again very disappointed


I planted them as per instructions. But I was so dissapointed they were puny and the flowers failed to turn and died before they grew into the correct shape. Heads were only about 3/4 of an inch in height and about as round as a 5p piece.

Spooky Hollow



I've bought this product several times, because it's useful.


I have planted these in swathes in the flower beds. They flower over quite a long period, and naturalise well. The bees love them.




Great for bees


Planted the bulbs in my borders, the bees loved them and even when they had died back they werecc CD quite attractive

The other varieties were beautiful


Disappointed so flimsy and not the bright colours in the photos




Lovely Alliums


Fabulous large heads on these alliums - much bigger than i expected. Last lasting and loved by bees and butterflies.

Look wonderful with other alliums (bought as a collection from Crocus) as they all flower at different times, and the seed heads are attractive too. The pollinators were in heaven in my front garden this summer with about 50 alliums to feast off!




beautiful bountiful bee food


These are fabulous bulbs for later on in the year after most alliums have finished but beware the rodents ...they seem to like them in spite of being garlicky!

Amazing flowers, high performance bulbs


These are late Spring bloomers,which is great for spreading interest over time. I massed plant them and they look great, especially when they sway with the wind.


Scottish Borders


These are great bulbs.


These are great feature bulbs in the flower bed. They tend to lean towards the sun so think about best place to put them. I moved some of mine from the front of border to the back

Hi, I didn't get round to planting my Allium sphaerocephalon bulbs in the Autumn - is it too late to plant them now? Thanks


Hello there No you can still plant now as long as the ground isn't frozen or waterlogged.

When should these bulbs be planted?

Mama Bookworm

Hello there The best time to plant them is now in the autumn. Hope this helps.



There was a time when alliums were thought of only as vegetables. However, the taller varieties with their huge globe flower heads are now one of the stars of the architectural plant world. The stiff lollipop heads off-setting sharp vertical leaves, tall,

Plant spring bulbs

Spring bulbs, such as daffodils and hyacinths, can be planted whenever the soil conditions allow. As a rough guide, cover them with about twice as much soil as the bulb is deep: so that a 5cm (2in) deep bulb would need a 15cm (6in) deep hole so that it
