Allium Purple Sensation

Allium ‘Purple Sensation’ is a striking and popular ornamental onion variety known for its large, globe-shaped flower heads composed of dozens of small, star-shaped, deep violet-purple florets. It typically grows to a height of about 90-100 cm (35-40 inches), making it an excellent choice for adding height and colour to garden borders and mixed plantings.

The flower heads of ‘Purple Sensation’ are about 10 cm (4 inches) in diameter and have a vibrant, eye-catching purple colour that stands out in mid to late spring gardens. The blooms rise atop tall, sturdy stems above clumps of strap-like green foliage, which begins to die back as the flowers reach their peak, leaving the dramatic blooms as the focal point.

This allium thrives in full sun and well-drained soil, and it is drought-tolerant and deer-resistant, making it a low-maintenance addition to gardens. ‘Purple Sensation’ works beautifully in mass plantings or when paired with other spring-blooming perennials like tulips, irises, or peonies. The dried seed heads also add interest to the garden later in the season or can be used in floral arrangements. Its bold colour and architectural form make it a favourite among gardeners for adding a touch of modern elegance to spring displays.
