Diervilla lonicera, commonly known as bush honeysuckle, is a suckering, densely branched, deciduous shrub that typically grows to 3' tall and to 4' wide. It is native to dry rocky open woodland areas and thickets from Newfoundland to Saskatchewan south to North Carolina, Tennessee and Iowa. It is noted for its small shrubby form, yellow trumpet-shaped flowers, dark green leaves and fall color. Tube-like flowers (each to 1/2" across), resembling the flowers of true honeysuckle (genus Lonicera), bloom in panicles (cymes) in late spring to early summer (June-July).
