Delivery detailsAllium 'Aflatuense Purple Sensation', also known as the purple sensation ornamental onion, is one of the most popular ornamental alliums for deep violet-purple globe flowers on tall, sturdy stems. You receive 25 dry bulbs in a bag, ready to plant. They are not growing plants.
The photos show the flowers in bloom.
Each bulb produces one large, rounded flowerhead in a rich purple-violet, held well above the border in late spring to early summer. The strap-like, grey-green leaves fade as the flowers open, so plant it among other perennials that will cover the gap. The tall stems are good for cutting, and the flowers attract bees and other pollinators. Planted in generous drifts, it suits borders, gravel gardens, prairie-style planting and cottage gardens, and it also grows well in pots.
Is it hardy? Yes, it is fully hardy and can be left in the ground all year. Plant the dry bulbs in autumn, between September and November, about three times the depth of the bulb's diameter and 10-15cm apart, in full sun. Choose well-drained soil, because alliums dislike sitting in wet ground. Water in after planting, and let the foliage die back naturally after flowering to feed the bulb for next year.
Bulbs are harmful if eaten. Keep away from children and pets.
