ALLIUM macleanii

Family

Liliaceae

Botanical Name

ALLIUM macleanii

Plant Common Name

Maclean's Onion

General Description

Native from Afghanistan to southwestern Asia, this bulbous perennial is grown for its dense umbels of star-shaped violet flowers which arise on tall stems in late spring and early summer. The long, strappy, glossy basal leaves wither as the flowers emerge. As with most ornamental onions, its leaves, stems, and bulbs are pungently scented.

Plant the bulbs in fertile, well drained soil at a depth two to three times their diameter. This plant likes ample sun and dryish summer conditions. Lift and divide the bulbs only when they become crowded. Plant this ethereal plant in groups in the mixed border, alpine bed, or rock garden.
