Habitat

Features

Robust high-climbing evergreen woody vine. Main stems woody up to 200 mm diameter at base, branching in upper ½ or less, bark grey-brown, furrowed, branchlets stout, pliant, glabrescent. Leaves dark and glabrous above, pale green and sparsely covered in white hairs beneath, 3-foliolate, (50-)-70-130-(10) × 60-120(-190) mm; leaflets coriaceous, broadly ovate to broad-oblong, cordate to truncate at base; margin entire to crenately toothed or lobed near apex, rarely deeply lobed to almost dissected; petiole (20-)30-60(-70) mm long. Flowers unisexual, in compound axillary dichasial cymes. Bracts paired; lower pair often leaf-like, united, usually inserted below middle of pedicel. Male flowers: sepals 6, imbricate, white, glabrous above, hairy beneath, spathulate to obovate or oblong, 25-35(-60) × 8-15-(24) mm; stamens numerous; anthers 1.5-2.0(-2.5) mm long; filaments sparsely hairy or glabrous. Female flowers: sepals 6, similar to male, (16)-20-25-(40) × 7-10(-13) mm; staminodes few. Achenes hairy, 2-4 mm long. Style (2.5)-3.5-6.5 cm long at fruiting, plumose. Fruits not persistent.

Similar Taxa

None - the usually entire, dark green, leathery leaves, and big white flowers serve to distinguish it from all indigenous, naturalised and exotic species in New Zealand, except C. armandii which differs from C. paniculata by its much larger leaves with lanceolate lobed leaflets and smaller white flowers.

Propagation Technique

Easily grown from seed. Can be grown by cuttings but these can be fickle and slow to strike. Prefers to be planted a permanently damp but not sopping soil, in a situation where it can grow up into the sun. Its root stock should never be allowed to dry out. In humid climates prone to powdery mildew.
