Red Carpet Onion (Allium ‘Red Carpet’)

Red Carpet Onion is a striking ornamental allium valued for its dense, globe-shaped blooms and rich rose-purple colour. This cultivar of Allium forms bold, rounded flower heads that add structure and visual interest to garden beds.

This herbaceous perennial produces upright stems topped with tight clusters of star-shaped flowers forming spherical blooms. The flowers appear in late spring to early summer and attract pollinators such as bees and butterflies. The foliage is slender and grass-like, typically fading as the flowers mature.

Red Carpet Allium is well-suited for borders, rock gardens, and pollinator-friendly landscapes. Its compact size and bold blooms make it ideal for front- to mid-border placement and mass plantings.
