Northern bush honeysuckle

Diervilla lonicera

''Diervilla lonicera'', commonly referred to as northern bush honeysuckle, low bush honeysuckle, dwarf bush honeysuckle, or yellow-flowered upright honeysuckle, is a deciduous shrub native to the northeastern United States and Canada. Its specific epithet, ''lonicera'' refers to its similarity in appearance to the true honeysuckles, genus ''Lonicera''.

Appearance

Northern bush honeysuckle is a deciduous shrub, reaching a maximum height between 0.6 and 1.2 metres. This particular species is known for the following characteristics: branches lying close to the ground, fibrous roots, pale yellow flowers, and dry, woody fruit. Northern bush honeysuckle's simple leaves are placed in an opposite arrangement. As the seasons change, so do the leaves' colours: initially green, the leaf gradually deepens to a dark red. The flowers are in full bloom between early July and early August; the woody seeds are fully matured by September in preparation for dispersal.

''Diervilla lonicera'' has protogynous flowers , is well-adapted for pollination, and its stigmas remain receptive after anthesis .

Status

Northern bush honeysuckle is generally abundant and widespread in North America; it is only considered to be threatened in Tennessee and rare in Indiana. Neither Canada, nor any of the other American states, has bush honeysuckle registered on a threatened or endangered list.

Habitat

Exposed rocky sites, combined with the plant's tolerance for cool climates, dry, or infertile soils are varying characteristics to describe a typical habitat for ''Diervilla lonicera''. It is commonly found in forests dominated by balsam fir and jack pine . Unlike some plant species that are restricted to specific light conditions, the northern bush honeysuckle is insensitive to changes in light, allowing for broader ranges of habitat. In addition, it is well-adapted to fire-prone habitats, because it can regenerate quickly from underground stems if destroyed by fire. For example, D.J. Schoen found that ''Diervilla lonicera'' was the most abundant shrub over a 50-year span on dry ground areas that were destroyed by fire.
