Picris hieracioides, or hawkweed oxtongue,[3] is a species of flowering plant in the family Asteraceae.
Description
[edit]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.
Ecology
[edit]Hawkweed oxtongue is native to Europe and Asia, but is an invasive species in Africa, Australia, and North America.[4] The plant can spread seeds rapidly, outcompeting native species, while also emitting a chemical inhibiting nearby plants' growth.[5]
