Dog fennel is a common name for Eupatorium capillifolium, a tall, weedy plant with feathery leaves. It is known for its strong odor and ability to grow in poor soils. Dog fennel is often found in pastures and along roadsides. The plant can become a nuisance in agricultural settings. Itβs like the fennel's less refined, more assertive cousin, often unwanted in gardens. Unlike cultivated fennel, dog fennel is considered a weed.
