|Botanical Name||Leycesteria formosa|
IdentificationShrub to 2-3 m high, stem green, hollow. The red-purple bracts which surround the small flowers in the terminal inflorescence are a conspicuous distinguishing feature. Leaf ovate up to 240 mm long. Flowers occur Dec-May. Fruit black brownish purple, 7-10 mm diameter.
HabitatsStreams, shrublands, light gaps in forests, potentially epiphytic niches, roadsides, exotic plantations, farm hedges and wastelands. Favours damper habitats.
Impact to Biota and EcosystemsCapable of penetrating deeply into untouched forest via natural light gaps. Favours windfall gaps and streamsides. Can form dense thickets especially in shrublands. Produces more shade than manuka but long term impact on forest regeneration is unknown.
Dispersal Routes, Vectors, Infestation SourcesMain infestation sources are roadsides and exotic forests. From these sites the plant then spreads to wasteland and native forest. Abundant seed dispersed by birds.
