Star of Persia Overview

Allium cristophii is a perennial flowering bulb that produces striking round shaped clusters of star-shaped violet flowers at the top of 50cm tall stems in early summer. Commonly known as the Star of Persia, this stunning bulb will produce leaves in early spring which will have faded by the time the flower has opened, making it a useful addition to mixed flower borders. These attractive flowers can be cut for floral arrangements or left to develop into seed heads giving structure to late autumn and winter displays. This species has earnt a Royal Horticultural Society (RHS) Award of Garden Merit. It is also part of the RHS “Plants for Pollinators” initiative to showcase plants which support pollinator populations by providing ample amounts of nectar and/ or pollen. A great choice for encouraging pollinating insect wildlife into your garden!
