Allium Cowanii, also known as Allium Neapolitanum, is an early blooming allium characterised by loose clusters of pure white umbels. Easy to grow, hardy and long lasting, it’s also a big attraction for birds and butterflies so a great choice for any landscape or garden.

Well suited to growing in drifts, it also works well when grown in containers, and makes an excellent cut flower. Buy your Allium Flower Bulbs from DutchGrown™ for Autumn delivery and planting.
