Threat Description

Morrow’s honeysuckle is a tardily deciduous, upright, arching-branched shrub that grows to 6.5 ft. in height. Its stem is opposite branched and light tan with a braided-strand appearance. Bark is often flaking, and older branches are hollow. Leaves, which persist in winter, are opposite in two rows, ovate to oblong, and up to 4 in. long. They have entire margins, short pointed tips, wrinkled upper surfaces, and soft-hairy lower surfaces. Fragrant flowers occur from February to June in axillary, bracted short-stemmed clusters, each with one to several white to yellow (some pink to red) flowers with five extended stamen. Petals are tubular, flaring to a four-lobed upper lip and a single-lobed lower lip. Abundant spherical, glossy berries paired in leaf axils occur from June to February. They are green becoming pink and ripening to red (sometimes yellow or orange) and usually persist in winter. Seeds are dispersed by birds and other animals and are long-lived in the soil. Morrow’s honeysuckle also colonizes by root sprouts. It is relatively shade tolerant and often forms dense thickets in open forests, forest edges, abandoned fields, pastures, roadsides, and other open upland habitats.
