Morrow’s honeysuckle is a multi-stemmed, upright, deciduous shrub that grows up to 7 ft. (2.1 m) tall. The leaves are opposite, round, 2-3 in. (5.1-7.6 cm) long and hairy underneath. Often it is one of the first shrubs to leaf out in the spring. The fragrant flowers are tubular, white to cream-colored, 3/4 in. (1.9 cm) in diameter and develop in the mid-spring. The abundant berries are 1/4 in. (0.6 cm) in diameter, ripen to orange or red in color, often persist throughout winter and occur on 1/2 in. (1.3 cm) pedicels. The bark is light brown and often pubescent on young stems. Several species of exotic bush honeysuckles occur and distinguishing individual species can be difficult. Morrow’s honeysuckle can often resemble Amur honeysuckle (Lonicera maackii), but Amur honeysuckle is taller (up to 10 ft. [3 m]), has larger leaves and nearly sessile berries. Morrow’s honeysuckle readily invades open woodlands, old fields and other disturbed sites. It can spread rapidly due to birds and mammals dispersing the seeds and can form a dense understory thicket which can restrict native plant growth and tree seedling establishment. Morrow’s honeysuckle is a native of eastern Asia and was first introduced into North America in the late 1800s. It has been planted widely as an ornamental and for wildlife food and cover.
