TAXONOMY:
The scientific name of northern bush honeysuckle is Diervilla lonicera
Mill. It is a member of the honeysuckle family (Caprifoliaceae). There
are no accepted subspecies. A variety with hairy leaf undersides occurs
in Ontario, northern Wisconsin, and northern Minnesota: D. l. var.
hypomalaca Fern. [13,15].

Northern bush honeysuckle is closely related to southern bush honeysuckle (D.
sessilifolia), from which it may not be specifically distinct [36].

Loomis and others [26] measured the moisture content of a number of
upper Midwest understory shrubs and herbs, including northern bush honeysuckle;
this information can be used for a number of fire management
considerations.

Northern bush honeysuckle is not named as an understory dominant or indicator in
published classifications. It is found in a variety of cover types and
has a number of plant associates. The most widely distributed shrub
associates of northern bush honeysuckle include beaked hazel (Corylus cornuta),
alternate-leaf dogwood (Cornus alternifolia), speckled alder (Alnus
rugosa), American green alder (A. viridis ssp. crispa), checkerberry
wintergreen (Gaultheria procumbens), and blueberries (Vaccinium spp.).
Herbaceous associates include wild lily-of-the-valley (Maianthemum
canadense), bigleaf aster (Aster macrophyllus), and wild sarsaparilla
(Aralia nudicaulis). Bracken fern (Pteridium aquilinum) is often
associated with northern bush honeysuckle in the understory of some cover types;
northern bush honeysuckle is also found on bracken fern-dominated grasslands in
northeastern Wisconsin [23,27,35,42,48].

Seed-tree cuts or clearcuts in red pine (Pinus resinosa) communities
often result in a dense growth of shrubs, including northern bush honeysuckle.
Northern bush honeysuckle increased in density following logging in a balsam fir
(Abies balsamea)-paper birch (Betula papyrifera) stand near Duluth,
Minnesota [34]. Leaving more of the canopy when logging reduces the
amount of shrub growth [12].

Northern bush honeysuckle competes with lowbush blueberry (Vaccinium
angustifolium) after fire-pruning of lowbush blueberry fields [17].

Northern bush honeysuckle is susceptible to foliar sprays of 2,4-D [6].

Northern bush honeysuckle is probably resistant to browsing; on Isle Royale,
Michigan, it was found in higher densities in control plots than in
moose exclosures [38].

The peak flowering season for northern bush honeysuckle is from early June to
early July, but flowers have opened as late as August in Michigan
[15,40]. The fruit matures and releases seeds in September [8].
