Allium 'Purple Rain' | Purple Rain Ornamental Onion
DESCRIPTION
Allium 'Purple Rain' is an ornamental onion prized for its giant, spherical flower heads composed of deep purple, star-shaped blooms. Flowering in late spring to early summer, the impressive, airy flower clusters sit atop tall, slender stems, creating a dramatic and architectural presence in the garden. The vibrant purple color contrasts beautifully with surrounding greenery, making it a standout feature in borders or mixed plantings.
Originating from hybridization efforts, 'Purple Rain' combines the best traits of Allium christophii and Allium ‘Purple Sensation', resulting in a plant with robust blooms and excellent garden performance. Its long-lasting flowers and bold structure make it an excellent choice for adding vertical interest, and its seed heads can be left to dry, offering additional ornamental value.
