Salmonberry (Rubus spectabilisis) is an invasive plant from the Raspberry family. Native to the west coast of North America, it was introduced in Victorian times to provide dense cover for game, since when it has spread out to colonise hedgerows, woodland and farmland.
Its lush dense growth, up to 2 metres, has a destructive effect on hedgerows and destroys native flora in woodlands.

How can I identify Salmonberry?

Salmonberry is a shrub growing to 1-4 metres tall, with perennial woody stems. The leaves are trifoliate, 7-22 cm long, the terminal leaflet larger than the two side leaflets, and the leaf margins are serrated.

The flowers are 2-3 cm diameter, with five purple petals, appear from early spring to early summer. The fruit matures in late summer to early autumn, and resembles a large yellow to orange-red raspberry about 2 cm long.

How can I get rid of it?

Eradication involves spraying the leaves during the growing phase, and this may involve several treatments to be effective.
