    These striking alliums can be planted in amongst perennials to add an extra layer of flowers, where they appear to 'float' above shorter perennials. Allium hollandicum 'Purple Sensation' is the all-time Chelsea Flower Show favourite and Allium nigrum has been used in many recent Chelsea gardens, proving alliums really stand the test of time. Bulbs will be delivered during August as soon as they are harvested from our specialist grower.

    In each collection you will receive 10 bulbs each of:

    Allium nigrum
    The naming of this plant refers to black, but the flower is in fact white. The wide grey-green leaves of this ornamental onion generally have started to die back when the flowers emerge in early summer (June). These sit on tall, sturdy stems forming flattish clusters that create a striking silhouette. Each creamy white flower has a pronounced ovary at its heart, which looks a little like a dark green pearl nestled in the centre. Grows to 75cm tall. Plant bulbs about 4in deep and 10in apart in September-October. Likes a sunny border.

    Allium hollandicum 'Purple Sensation'
    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 globe-like architectural silhouette makes it particularly well suited to gravel or prairie-style planting schemes. These alliums are renowned for their large flower heads, which are just as attractive after they have finished flowering as seed heads. Plant bulbs about 6in deep and 6in apart to enjoy the full effect of the flowers. Winner of the prestigious Royal Horticultural Society AGM. Grows to 1m tall. Also plant in September-October.
