Crocosmia crocosmiiflora


New Zealand Status: Introduced
Conservation Status: Naturalised

Crocosmia crocosmiiflora, commonly known as Monbretia, is a vigorous, spreading perennial herb that was created by crossing C. aurea with C. pottsii in France in the 1880's. It grows from flattish, light-brown, corms 35 x 15mm with a fibrous covering. New corms are continually produced on short stolons enabling the plant to rapidly form large, dense clumps.

Crocosmia crocosmiiflora prefers moist soils and is commonly found along stream and river banks, forest margins, alluvial plains, roadsides, gravel pits, wasteland, slips and shrubland. It outcompetes native plants, particularly in native bush and riparian areas and is listed as an Environmental Weed in New Zealand.
