1 easy-to-kill weed
Distinctive features: bushy, spreading, hairless, smelly, perennial. Can get to 2m high (or more if supported) and has a deep, pliable taproot. The hollow, brittle stems are softly woody near the base and usually reddish. The narrow, oval leaves (40-150mm x 15-50mm) alternate. They are light green when young, but occasionally turn reddish in autumn. From November to August dense, erect, cylindrical flower clusters (up to 7cm long) are produced along the main stem and turn from green to pink. They are followed by succulent, juicy, purple-black berries (8mm in diameter) containing seeds.
Why is it weedy: inkweed grows and matures quickly and spreads a lot of long-lived seeds over a wide area. It tolerates wind, fire, and wet to moderately-dry conditions. Will compete for space with pasture, and inhibit the establishment of native seedlings.
How does it spread: birds, movement of soil, and by water.
How to kill it
1. Pull out small plants and leave on site to rot down. 2. Slash stems close to ground and leave on site to rot down. 3. Cut down and paint stumps (all year round): metsulfuronmethyl 600g/kg (1g/l).
Look for 7cm-long flower clusters, followed by purple-black berries
