The currently accepted scientific name for dogfennel is Eupatorium
capillifolium (Lam.) Small (Asteraceae) [2,6]. Eupatorium
compositifolium Walt. and E. leptophyllum D.C. are closely related
species which some authors include as varieties of E. capillifolium
[2,11]. There are no recognized subspecies or varieties.

and New Jersey. It is occasional farther north along the East Coast to
Massachusetts [2].

HABITAT TYPES AND PLANT COMMUNITIES :
Wells [18] cited dogfennel as a dominant of mid-seral, coastal meadows
in his classification of Coastal Plain community types.
MANAGEMENT CONSIDERATIONS
SPECIES: Eupatorium capillifolium
IMPORTANCE TO LIVESTOCK AND WILDLIFE :
Dogfennel has no value as forage for wildlife and livestock [9,15].
PALATABILITY :
Dogfennel probably has very low palatability. Cattle graze it sparingly
if at all, even when other forage is scarce [9].
NUTRITIONAL VALUE :
NO-ENTRY
COVER VALUE :
NO-ENTRY
VALUE FOR REHABILITATION OF DISTURBED SITES :
NO-ENTRY
OTHER USES AND VALUES :
NO-ENTRY
OTHER MANAGEMENT CONSIDERATIONS :
Dogfennel may serve as a reservior for disease-causing pathogens when
growing among food crops [4].
Dogfennel is scarce on forest ranges in good condition [9]. Grazing
forage utilization in excess of 65 percent will favor dogfennel
establishment [3]. Dogfennel presence may indicate overgrazing.
BOTANICAL AND ECOLOGICAL CHARACTERISTICS
SPECIES: Eupatorium capillifolium
GENERAL BOTANICAL CHARACTERISTICS :
Dogfennel is a common, aggressively weedy native of the southeastern
United States [2,14]. It is alternately described as an annual [2,9,16]
and a perennial [6,14]. It has several stems arising from a stout woody
caudex. It grows in distinct colonies on favorable sites. Dogfennel
normally reaches 4 to 5 feet (1.2-1.5 m) in height but can reach up to 9
feet (2.7 m) on fertile sites [9]. The fruit is a smooth achene [9].
RAUNKIAER LIFE FORM :
Hemicryptophyte
Therophyte
REGENERATION PROCESSES :
Dogfennel is wind pollinated [9]. Following the typical pattern of
weedy plants, dogfennel's primary mode of regeneration is probably
sexual. Its regeneration strategy probably depends on the production of
a great many wind-dispersed seeds.
SITE CHARACTERISTICS :
Dogfennel grows on disturbed sites in the Southeast. It is common on
young burns in the loblolly pine (Pinus taeda)-turkey oak (Quercus
laevis) type in Florida's Ocala National Forest [10], on recent burns in
the Okefenokee Swamp [1], on burned and cut Atlantic white-cedar
(Chamaecyparis thyoides) sites in the Great Dismal Swamp [14], and on
overgrazed sites in Louisiana [3]. Dogfennel is a frequent invader of
everglades sawgrass (Cladium sp.) communities during drought [7,13].
Other dogfennel sites include meadows, swales, old fields, pond borders,
ditches, disturbed or overgrazed pastures, and roadsides [9]. Although
apparently able to grow on a variety of soils, it is most common on dry,
sandy soils [9].
SUCCESSIONAL STATUS :
Obligate Initial Community Species
Dogfennel is intolerant of closed or highly structured communities [9].
It is undoubtedly an early seral, if not an invader, species in most
successional progressions within its range.
SEASONAL DEVELOPMENT :
Dogfennel biomass peaks in the spring [14]. Its flowering period is
unusually long because shaded plants bloom earlier than those in full
sun. A population of dogfennel near Gainsville Florida had the
following phenological sequence [3].
Phenological event Timing
------------------ -----------------------------
Flowering late August - early November
Fruit ripening early - mid November
Fruit dispersal late November - early December
Drying late November - mid January
Dormancy mid January - early March
Bolting early April - June
FIRE ECOLOGY
SPECIES: Eupatorium capillifolium
FIRE ECOLOGY OR ADAPTATIONS :
The fire ecology of dogfennel has not been adequately described.
Dogfennel probably depends on off-site seed sources to colonize
recently burned areas. Sprouting from a surviving caudex may also
occur.

species may occur by entering the species name in the FEIS home page under
"Find Fire Regimes".
POSTFIRE REGENERATION STRATEGY :
NO-ENTRY
FIRE EFFECTS
SPECIES: Eupatorium capillifolium
IMMEDIATE FIRE EFFECT ON PLANT :
Most fires probably kill or at least top-kill dogfennel. Its caudex may
survive cool fires.
DISCUSSION AND QUALIFICATION OF FIRE EFFECT :
NO-ENTRY
PLANT RESPONSE TO FIRE :
The presence of dogfennel on recently burned sites [1,10,14] indicates
that seedling establishment and/or sprouting occurs following fire.
DISCUSSION AND QUALIFICATION OF PLANT RESPONSE :
NO-ENTRY
FIRE MANAGEMENT CONSIDERATIONS :
NO-ENTRY
