Northern bush honeysuckle (Diervilla lonicera) is a low, deciduous shrub native to northeastern North America, valued for its pale yellow summer flowers that attract bumblebees. It is hardy and tolerant of cool, dry, or infertile sites, and is not a true honeysuckle (Lonicera).

About
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 (the Latin term for ‘honeysuckle’) refers to its similarity in appearance to the true honeysuckles, genus Lonicera. It attracts bumblebees and is an important source of nectar for them.
Where it grows
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 (Abies balsamea) and jack pine (Pinus banksiana). 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.
