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.

  • Propagation Research

Although studies in propagation have been conducted, no research program is in place.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).

Localized Southern Appalachian endemic. Occurs in a few counties in northwestern Georgia (where it is locally abundant) and in only a few counties in northeastern Alabama. Rare in Tennessee; historical in North Carolina.

Comparative genetic study of the three Diervilla species would be helpful, as their taxonomic status is not yet clarified. Population identification and monitoring would be useful in devising a protection plan.
