Erect woody shrub <3m tall. Leaves composed of 3 green, hairy leaflets, the middle one being longest. Single or clustered bright yellow flowers (May-Nov) on short spikes. Pods release seed by explosion summer.
Riverbeds, waste places, hill country, coastal sites. Very cold tolerant.
Localised seed spread from bursting pods.
A light-lover, so can be succeeded in tall canopy habitats by taller native spp. where their seedlings exist. These sites can be left, however slashing, selective spraying or replanting of shade-creating spp can increase regeneration rate. Clear roads, metal dumps, quarries. Maintain pest & livestock control, as plant is not browsed as readily as native spp. & recovers more quickly from browsing.
1. Hand pull, dig or grub out small plants before seeding, minimising soil disturbance.
2. Cut & stump paint (5g metsulfuron/1L or 50ml triclopyr/1L).
3. Weed wipe spring - summer (250ml triclopyr/1L).
4. Spray spring - summer (60ml triclopyr +10ml penetrant/10L).
