About this weed

This erect perennial herb grows to about 1.5 metres high and is often found in wetlands and creeks. These photos were taken at Herdsman Lake Regional Park. The plants originated in Europe and Asia and are easily identifiable when flowering as they have tall flower spikes with dense green flowers that produce heart shaped brown fruit.


Curled Dock is a tall, perennial herb. It produces green flowers and primarily reproduces by seed. The seed is then dispersed by animals, soil and machinery. The seedbank persists for 20+ years.
