Miconia spp

Description

This is a small evergreen perennial shade tolerant tree which grows to 15 metres. Leaves are attractive, growing to about 1 metre. They are dark green on top and reddish-purple beneath, with 3 prominent ivory veins on each. Leaves are arranged opposite each other on the stem.

Flowers are numerous and sweet scented, white to pink and short-lived. It flowers in autumn.

Fruit at maturity are dark purple-to-black fleshy berries, up to 1.5 centimetres wide in panicles, with each fruit containing numerous seeds.

Habitat in rainforests.

Weed characteristics form dense stands, aggressively invading to shade out native plants. Miconias also have the potential to degrade crop, plantation and pasture areas. It is a shallow-rooted tree which creates hillside instability making it an erosion threat. It is the target of a national eradication program.

Dispersal is by birds, vehicles, machinery, footwear and animals. Mature plants can produce up to 3 million seeds several times per year, creating a massive soil seed bank. Seeds can persist in the soil for more than 8 years.
