From the article Picris hieracioides on Wikipedia (CC BY-SA), quoted section by section
Description
Hawkweed oxtongue is described as having long and narrow simple leaves, with or without teeth, resembling an ox's tongue. The leaves at the base form a rosette, while the stems can grow up to 1 metre (3.2 feet) in height. The plant blooms in summer, producing small, yellow flower with many petals, somewhat resembling a dandelion.
What it does
Hawkweed oxtongue is native to Europe and Asia, but is an invasive species in Africa, Australia, and North America. The plant can spread seeds rapidly, outcompeting native species, while also emitting a chemical inhibiting nearby plants' growth.
