Vigorous, erect, perennial shrub <3m tall but more commonly 1-2m. Long-lived & partly deciduous in winter. Offensive-smelling leaves alternate, wavy, hairless, lance-shaped & <12cm long. C. elegans has magenta-crimson flowers & crimson berries and C. fasciculatum has scarlet-purple flowers & dark red berries.
Waste areas, stream banks, near gardens, bush margins, gullies, alluvial flats. Prefers higher rainfall areas. Very frost tolerant.
Seeds dispersed by birds & water. Pieces of cut root spread by cultivation. Also reproduces vegetatively from buds from creeping roots. Seeds remain dormant in the soil for many years.
Extremely toxic to farm animals. Dense infestations exclude virtually all other vegetation.
Hard to distinguish from many native spp. (apart from foul smell), best controlled when in flower. Wear gloves when handling, exclude stock at all times. Replant bared sites to minimise regrowth. Check for seedlings 6-monthly.`
