Sometimes known as the violet trumpet vine or the Argentine trumpet vine, this climbing plant comes into bloom in October in Sydney gardens. Hailing from southern Brazil and Argentina, it has the characteristic flared trumpet flowers of members of the Bignonia family (Bignoniaceae). These are mauve with purple veining, and reminiscent of foxgloves, and they appear in profusion. Foliage is glossy. It will climb to around 3.5m or more and needs the support of a pergola or fence. It seems to do best in full sun, with adequate moisture, especially in its early years.
It is regarded as frost tender. It is best to prune it back after flowering to keep the growth compact. It can be propagated by cuttings taken in spring; mine resulted from a small piece snapped from a vine spotted during a stroll around the neighbourhood some years ago!
