Diervilla lonicera — bush-honeysuckle

Facts

Bush honeysuckle is a small (3 feet or 1m tall) shrub of rocky, cool forests, with opposite leaves and a terminal cluster of yellow-orange flowers. Although bush honeysuckle is rarely dominant in forest understories, it provides both winter and summer browse for deer and moose. Because it freely suckers and produces bell-like yellow flowers, this species is considered a good native substitute planting to use in place of the non-native and invasive honeysuckles.

Habitat

Alpine or subalpine zones, anthropogenic (man-made or disturbed habitats), forest edges, grassland, talus and rocky slopes, woodlands
