Common ragwort
Senecio jacobaea
Family: Asteraceae
Fire effect on plant
Plants may be top-killed by fire with the root or root crown surviving (Tasman Council 2013).
Key traits
Large persistent soil seed bank that germinates readily after fire. Seeds are mainly wind dispersed. The roots have the capacity to form perennating buds, which can support resprouting (Jacobs and Sing 2009).
Plant response to fire
Common ragwort responds readily to disturbance such as fire. Fire may create new openings favorable to ragwort seed germination (Jacobs and Sing 2009).
Timing of life history
A perennial. Seeds likely produced from second growing season. Flowering May to October.
Conservation status
None.
