Allium Cowanii

(inc. 20.0% VAT)



Fast becoming a florist favourite, Allium ‘Cowanii’ produces loose umbels of delicate white, star shaped blooms in May.  The flowers also smell sweet, rather than oniony, as you might otherwise expect from a member of the Allium family.

Sometimes known as Allium Neapolitanum, this charming cultivar is easy to grow and looks best in snowy drifts, weaving through the front of a border where it will take your garden seamlessly from spring, into summer.

The bulbs of Allium ’Cowanii’ may also be grown in pots of fertile, very well-drained soil. 

A space in full sun is best reserved for this pollinator-friendly spring gem.
