Hawkweed Overview

Hieracium is very large genus containing around 2882 species of herbaceous perennial flowering plants in the daisy family, Asteraceae (historically Asteraceae). They are native to Africa, Eurasia and the Americas and commonly known as hawkweeds. They are characterised by a basal rosette of smooth-edged or toothed leaves and usually yellow or orange, daisy-like summer flowers. In the UK they are often included in wildflower gardens but in other countries such as New Zealand, Australia and the US, they are considered to be invasive pest species. These plants are easily confused with species in the genus Pilosella, they are difficult to distinguish between from photographs alone. The main difference is larger fruit size in Hieracium species compared to Pilosella plants, which also have more creeping stems.
