Diervilla rivularis 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, Fernald 1949). 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.
Distribution & Occurrence
- North Carolina
Damp woods and rocky banks to full sun at disturbed areas (along roads) (Small 1933, Fernald 1949, Clark 1971, Dirr 1988, Foote and Jones 1994).
|Remaining population sites and sizes are largely unknown.|
Conservation, Ecology & Research
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
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).
Population identification and monitoring would be useful in devising a protection plan.
