Distribution of swamp doghobble in US.

General Distribution

Swamp doghobble is widely distributed throughout the Coastal Plain of the southeastern United States from eastern Massachusetts to southern Florida and west through the Gulf States to southeastern Texas [10,14].

States and Provinces

  • United States: AL CT DE FL GA LA MD MA MS NJ NY NC PA RI SC TN TX VA

Site Characteristics

Swamp doghobble grows on a variety of sites in the coastal plains of the southeastern United States but is restricted to climates with mild winters and long, hot, humid summers. It grows best in shrub-tree bogs, cypress (Taxodium spp.)-gum (Nyssa spp.) depressions, along marshy streambanks, and forest edges [2,15].

Plant Communities

Swamp doghobble is an important shrub species in pocosins [1,11]. Common overstory associates include swamp blackgum (Nyssa sylvatica var. biflora), loblolly bay (Gordonia lasianthus), sweetbay (Persea borbonia), red maple (Acer rubrum), titi (Cyrilla racemiflora), and southern white cedar (Chamaecyparis thyoides). Understory associates include hurrahbush (Lyonia lucida), sweet pepperbush (Clethra alnifolia) southern bayberry (Myrica cerifera), and laurelleaf greenbrier (Smilax laurifolia) [1,3,4,5].

Botanical Description

Swamp doghobble is a small to large, widely branched, deciduous shrub [7,10]. It is prostrate to erect in form, reaching heights between 3 to 12 feet (1.0 - 3.5 m). The leaves are short, thin, and smooth with the smaller leaves occurring on the twig among the larger leaves. The short, tubular flowers are borne in clusters at the end of the stems. The fruit is a five-part capsule that persists over the winter [14,20].

Raunkiaer Life Form (Raunkiaer 1934)

  • Phanerophyte

Seasonal Development

Swamp doghobble begins extensive growth in early March and peaks in growth in early summer [17]. It flowers between April and June [20].

Regeneration Processes

Swamp doghobble reproduces vegetatively by sprouting from adventitious buds on the roots following disturbance [21]. It also regenerates sexually, although the details have not been described.

Successional Status

Swamp doghobble is an early- to mid-seral species that is intolerant to shade and grows best in full sunlight [3,15]. In a southern white cedar forest in southeastern North Carolina, swamp doghobble was present in the initial stages after disturbance, gradually reduced in the middle-age forest, and disappeared in the mature forest [3].

Immediate Fire Effects

Fire typically top-kills aboveground portions of swamp doghobble [4].

Postfire Regeneration Strategy (Stickney 1989)

  • Survivor species; on-site surviving root crown or caudex
  • Off-site colonizer; seed carried by animals or water; postfire years 1 and 2

Fire Adaptations

Fire does not usually invade the wetlands and lower slopes of the floodplain because the soil and duff layers are usually very damp [11,21]. Shallow burns favor swamp doghobble because of its ability to sprout quickly after aboveground portions of the plant are killed [1,4].

Plant Response to Fire

Swamp doghobble will sprout from adventitious buds on the root following fire [4].
