Allium cristophii, commonly known as Star of Persia, is a deciduous perennial bulb native to rocky slopes and dry meadows in Central and Southwest Asia, particularly Iran and Turkey. It reaches a height of up to 50 cm (20 in) and is notable for its large, spherical umbels of silvery pink star-shaped flowers, each umbel measuring 20–25 cm (7.9–9.8 in) in diameter, blooming in early summer. The flowers are highly ornamental and are followed by equally attractive fruiting clusters. The foliage is basal, with broad, strap-shaped leaves that die back before flowering. Star of Persia is valued for its striking floral display and architectural form.

This Allium species is favored for its ease of maintenance and drought tolerance, making it suitable for rock gardens, borders, and cottage gardens. It is also used for cut flowers and dried arrangements due to the persistent beauty of its seed heads. A. cristophii thrives in full sun to part shade and requires well-drained, sandy or gritty soil. It is hardy in USDA zones 5–8 and benefits from a dry period in late summer when the bulb is dormant. Caution should be taken as it is toxic to cats, dogs, and horses. The plant has been recognized with the Royal Horticultural Society’s Award of Garden Merit for its outstanding qualities.CC BY-SA 4.0
