Weed out this nasty cur­rant

WHAT IS IT?

De­cid­u­ous shrub (1-2m high) with broad, hairy, veined leaves (2-7cm long) di­vided into 3-8 lobes. Groups of 5-30 red or pink flow­ers (5-10mm di­am­e­ter) are pro­duced in early spring, and fol­lowed by oval, dark pur­ple berries (1cm long).

WHY IS IT WEEDY?

Flow­er­ing cur­rant forms dense stands along wa­ter­ways and in shrub­lands, crowd­ing out na­tive species. It sprouts from root crowns, and stems can also take root when they touch the ground, form­ing new plants. Heavy seed crops oc­cur ev­ery sec­ond or third year and 45kg of berries will yield about 1.8kg of seed (ap­prox 500,000 seeds) that are spread by birds and small mam­mals.

WHICH HABI­TATS IS IT LIKELY TO IN­VADE?

Open bush ar­eas, for­est gaps, dry rocky slopes and dis­turbed sites from sea level up to just un­der 2000m. Prefers sun or par­tial shade.
