Invasive Plant

Orange Hawkweed

Hieracium aurantiacum

About This Species

Originally from Europe, Orange hawkweed can create dense mats that crowd out native plants. Hawkweeds spread quickly through above ground runners, horizontal roots, and seeds. Agriculture and recreational activities, wildlife, and wind can help the spread of hawkweeds. One plant can produce hundreds of seeds. It is considered a noxious weed in many parts of BC.

How to Identify

Orange hawkweed grows from 30 -60 cm in height and has bright orange-red flowers clustered at the top. Plants have bristly-hairy leaves and stems, with few to no leaves found on the stem. Stems contain a milky fluid when broken open.
