Perennial. Seeds germinate in September and the plant regenerates from root suckers, layers and crown. Can reproduce both sexually and asexually (Keller, 1983). Soil bank does not survive beyond the first season (Atkinson 1997). Seed is produced at approximately 15 000/m squared ground projection. Seeds are not viable after the first season and are dispersed by vertebrates; birds and possums.

Reason for introduction
Disposal Method - replant bare sites to minimise seeding. Preferred Control - cut stem and apply vigilant as per the label. Can be done all year round. Alternative Control - stump swab: Escort label rates or Tordon Brush Killer, 10%.
The plant has a high tolerance of shade (McQueen 1993), drought and frost and is only slightly tolerant of poor drainage. After physical damage and grazing resprouting occurs from all parts.
berberis: From the Arabic name berberys
