Buy Allium caeruleum blue allium bulbs (syn. Allium azureum): Beautiful globes of bright blue flowers

  • Position: full sun
  • Soil: fertile, well-drained soil
  • Rate of growth: average
  • Flowering period: June to July
  • Hardiness: fully hardy
  • Allium bulb size: 4/-

    This stunning blue ornamental onion is ideal for a sunny border. Dense globes of small, star-shaped, bright blue summer flowers on stiff stems and narrow, mid-green leaves. Since the leaves die back before the flowers emerge it’s best planted with other medium-sized herbaceous plants, such as sea holly, which help to mask the faded foliage.

  • Garden care: Plant 8cm (3in) deep in naturalistic drifts in September or October in a well-drained, sunny site. Split and divide large clumps in autumn or spring.

  • CAUTION do not eat ornamental bulbs

Lovely!

These will ONLY grow and flower if planted in sunny and well drained soil. At least that is what happened to me when I trialled them in three different positions. Clay soil and sun in South facing border = NO SHOW. Well drained soil and partial shade in West facing border = NO FLOWER. Those that did flower were lovely. A vivid blue!

Had great expectations of this plant. Only a couple of bulbs grew and were nothing like the picture. This year didn't grow at all

Unfortunately none of them grew, or at least they didn't flower if they did grow. Not sure if I'm unlucky or if they're prone to pests eating them.

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
