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.

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).
