What does false yellowhead look like?
- False yellowhead is an erect, bushy perennial (long-lived) shrub growing to 1.5 metres high. Young stems are covered in sticky hairs that give out a foul smell when crushed. The leaves are grey-green and serrated at the edges. The flowers are yellow and daisy-like and occur in clusters of 4-12 flowers. The root system is large and robust, making the plant difficult to pull out.
- Germination occurs mostly in autumn after rain, but can occur at any time when moisture is available. Flowering occurs from mid-summer to mid-autumn.
- False yellowhead spreads by seed. The seed has a bristly pappas (like a small parachute) which catches the wind or allows the seed to float in running water. Seed is also spread in contaminated soil and on machinery.
