Allium Ostara

(inc. 20.0% VAT)



Rich purple-red flowers dazzle and gleam in the early summer garden as they rise and bloom on sturdy stems during May and June.

Allium ‘Ostara’ is a cross between two other popular species of Allium – Atropurpureum and Karataviense and blends the best qualities of both varieties together with attractive, broad leaves and luscious burgundy flowers.

Plant the bulbs near to the front or middle of a perennial border or in a large container situated in full sun.

The large and distinctive flowers are long lasting, excellent for cutting and highly attractive to pollinators.
