Eupatorium capillifolium, or dog fennel (also written "dogfennel"), is a North American perennial

dill pickles.[5]
The flowers have a subtle floral odor.

Classification

Dogfennel is closely related to Eupatorium compositifolium (yankeeweed) and Eupatorium leptophyllum and some authors consider all of them varieties of E. capillifolium.[6] Others maintain them as three species but consider them a related group, known as dogfennels or the Traganthes group. They all are characterized by dissected leaves.[7][8]

Cultivation and uses

Dog fennel thrives on roadsides,

Bahamas.[11] Unlike insect-pollinated plants in this genus, E. capillifolium is wind-pollinated.[11]

Dog fennel is eaten by Florida's scarlet-bodied wasp moth, Cosmosoma myrodora. These moths feed on the plant while mature, to store its toxins and ward off predators.

Control

Dog fennel spreads by both seeds and

rootstocks and can grow quite aggressively. It is common in pastures, especially those that are unimproved or overgrazed,[6] and degrades the quality of the pasture by competing with desired forage species.[12] Dog fennel contains liver-damaging pyrrolizidine alkaloids
, so livestock are known to eat all the turf around a stand of it. To remove infestations of dog fennel, the recommended course of action is to mow it before it can seed.

It has also been introduced outside its native range, for example in Nepal.[13]

Toxicity

Dog fennel contains pyrrolizidine alkaloids which can cause liver failure.[14]

Medicinal uses

Eupatorium capillifolium is extracted into an essential oil and has anti-fungal properties.[15]
