Asian bush honeysuckle
(Lonicera maackii, L. tatarica, L. morrowii, and L. x bella)
Description: These upright shrubs with arching branches are 6-15 feet tall. Each of these species has dark green egg-shaped leaves. They stand out in the understory of forests as the first shrubs to leaf out in the spring and the last to lose leaves in the fall. The paired, tubular flowers are white on Amur and Morrow honeysuckle and pink on Tatarian honeysuckle. Berries range from red to orange and are dispersed by birds.
Threat: Rapidly forms a dense shrub layer that excludes native understory shrubs, decreases species richness, reduces canopy tree growth, increases ticks and tick-related illnesses.
