Diervilla sessilifolia


Diervilla sessilifolia is a North American shrub named in compliment of a French traveler, N. Dierville, who first brought the plant from Canada to Europe in 1699 (Small 1933). There are three Diervilla species, all of them eastern North American: D. lonicera, D. sessilifolia, and D. rivularis (Fernald 1949). All three are deciduous shrubs of small to medium size, spreading by means of underground stems and forming colonies.

State Range of  Diervilla sessilifolia
Habitat
  Mountain woodlands, bluffs, stream banks, and road banks (Small 1933, Fernald 1949, Dirr 1988, Foote and Jones 1994).

Distribution
  Historically, this species ranged from Georgia, Alabama (north to Warren Co.) to the mountains of northwestern Virginia (the Blue Ridge), West Virginia Radford et al. 1968, Foote and Jones 1994) and Tennessee (Small 1933, Fernald 1949, Clark 1971, Dirr 1988, Foote and Jones 1994).

Conservation, Ecology & Research

Ecological Relationships
  Ecological relationships are unknown.

Threats
  Road construction, right-of-way maintenance
Hydroelectric facilities, dams
Erosion after logging
Disturbance by thinning trees in the immediate proximity
Overtopping by arboreal species or fast growing herbs or vines
Natural habitats vanish due to plant succession
Invasive species

Current Research Summary
  Research other than propagation is not known.
• Propagation by seed (sow directly, without pre-treatment) brings consistent good result (Bir 1992).
• Propagation by softwood cuttings: in June-July, 2,500-5,000 ppm K-IBA, under mist or fog (easily rooted).

Current Management Summary
  There is no formal management plan.

Research Management Needs
  Comparative genetic study of the three Diervilla species would be helpful, as their taxonomic status is not yet clarified.
