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.

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). |

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. |
