Leaves: opposite; deeply, pinnately lobed; joining at stem to form cup; prickly.

Discussion Cut-leaved Teasel spreads by seeds and can quickly form a monocultural stand, outcompeting all other flora, including native species. If unchecked, this aggressive teasel can damage sensitive native habitats such as prairies. It is considered a noxious or invasive pest in North America.
