Montbretia (Crocosmia × crocosmiiflora) is a long-lived, deciduous perennial herb that is native to a cultivated hybrid of South African species. It was introduced to New Zealand as a garden ornamental and was first recorded in the wild (naturalised) in 1935. The plant grows up to about 1.5 metres tall from underground corms and has erect, sword-shaped leaves. It flowers from December to February, producing arching sprays of orange to red, funnel-shaped flowers, which develop into seed capsules. It reproduces vegetatively from corms and cormels, and occasionally by seed. Seeds are dispersed by water. Corms and cormels are spread by soil movement, dumped garden waste and other human activities. Corms readily produce new plants.
