Family

Iridaceae

Botanical Name

CROCOSMIA x crocosmiiflora 'Norwich Canary'

Plant Common Name

Crocosmia, Montbretia

General Description

Herbaceous perennials native to South Africa, crocosmias are best known in gardens by "montbretia" hybrids such as this recent Dutch introduction. In summer, its spreading clumps of sword-like leaves give rise to knee-high, slender, arching spikes of small tubular flowers with six spreading lobes. The gladiolus-like blooms are golden yellow with orange-tinged exteriors. Plants grow from bulb-like corms that spread by underground stolons.

This montbretia is eye catching in the sunny border when grown in fertile, well-drained soil. It can be mulched to boost winter hardiness, or its corms can be lifted and stored. It attracts bees, butterflies, and hummingbirds, and is excellent for cutting. A vigorous spreader, it should be divided every few years to maintain a nice clump.
