(syn Dipsacus sylvestris)
Growth Habit: Teasel is commonly found in large clumps in damp areas, such as drains and creeks. The leaves have rough surfaces, oblong up to 50 cm long and form a rosette. It has stout flowering stems that can grow up to 2m in height. The stems are square in cross-section and are prickly, with stem leaves lanceolate, opposite and shorter than rosette leaves. It has a deep fleshy, yellow taproot.
The plant’s characteristic seed heads were formerly used to tease out impurities in wool, hence the common name teasel.
Type of Plant: A stout biennial herb.
Dispersal: Seed is moved short distances by water and soil movement.
Distribution: Teasel can be found in waste places, roadsides, creek banks and damp places. It is occasionally found in run down pastures.
