    Strap-shaped grey-green leaves start to die back before the densely packed umbels of deep violet, star-shaped flowers appear in early summer. Its striking architectural silhouette makes it particularly well suited to gravel or prairie-style planting schemes.

  • Garden care: Plant bulbs 15cm deep and 15cm apart to enjoy the full effect of the flowers. Avoid excessive soil moisture, and split and divide large clumps in autumn or spring.

  • CAUTION do not eat ornamental bulbs

    Comments about Allium hollandicum 'Purple Sensation':

    Good sized firm bulbs. Great for adding colour between the early spring bulbs and the summer perennials. Seem happy on most soils in most aspects and resilient and maintenance free. Only problem so far squirrels digging them out to bury walnuts!

        You can cut them off whenever you like, but I tend to leave my seed heads on for as long as they look good, which is usually in autumn.

      Why do my Allium leaves get dry and yellow? I watered, but it did not help, And then reduced watering but again it did not help.

        The foliage of these plants does not last very long at all, and as the plants energy is diverted into producing the flowers, by the time these open, the leaves are looking pretty tatty. This is completely normal so nothing to worry about, but I would recommend giving the plants a good feed now with a general purpose fertilser.

    • Q:

      What size pot would be the minimum for these bulbs? I recently purchased a batch of these bulbs from Crocus and have some pots in mind. They are square pots, about 30cm x 30cm x 40cm high. Could I get away with four per pot?

        Hello there
        Yes these pots should be fine, but I would plant more bulbs per pot, approx a bulb width apart as then they have more impact. Also make sure that they don't dry out during the spring otherwise the flower buds can then fail to open.
        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
