DESCRIPTION
Lonicera xylosteum is a woody, perennial shrub that is 1-2 m (3-7 ft.) tall. The pubescent stems of this plant are hollow. The oppositely arranged, gray-green leaves are are usually obovate in shape, but can be ovate or oval; they are broadest beyond the middle. The apex of the leaf is usually obtuse, but can be acute and the base of the leaf is subcordate to narrowed. The upper leaf surface is glabrous when mature while the lower leaf surface is pubescent. The leaves measure 2.5-7.5 cm (1-3 in.) in length. The yellow-white flowers are borne in pairs on peduncles that are longer than the petioles. The corolla of the flower is pubescent and conspicuously 2-lipped. The flowers appear in late May to early June. The fruit are scarlet, spherical berries that are borne in pairs. They usually measure 6 mm (0.25 in.) in diameter and ripen in the late summer to early fall.

Link to the key of exotic honeysuckles
The key above does not include the native bush honeysuckles. One way to differentiate between the invasive bush honeysuckles and the native ones is that the invasive honeysuckles all have hollow stems, while the stems of the native ones are solid.
REPRODUCTIVE/DISPERSAL MECHANISMS
The fruit of Lonicera xylosteum, similar to the other shrubby honeysuckles, is dispersed by birds.
DISTRIBUTION
The native range of Lonicera xylosteum is in Europe, east to Turkey and the European part of Russia. In the United States it has been reported from all the northeastern states, south to Virginia, and West to Missouri and Minnesota. It has also been reported in Oregon. Lonicera xylosteum has been reported from all of the New England states.
HISTORY OF INTRODUCTION IN NEW ENGLAND
Lonicera xylosteum has long been cultivated, and there is no known date for its first introduction into this country. It was most likely introduced for use as a horticultural plant, and spread via plantings and bird dispersal.
HABITATS IN NEW ENGLAND
Abandoned Field,Early Successional Forest,Edge,Floodplain Forest,Open Disturbed Area,Pasture,Planted Forest,Roadside,Utility Right-of-Way,Vacant Lot,Yard or GardenLonicera xylosteum can be found along the edges of woods and in open canopy forests. Like the other shrubby honeysuckles, it is tolerant of a wide range of soil conditions, and is used in for landscaping in difficult spots. It prefers full sun, but can also tolerate low light conditions.
THREATS
Lonicera xylosteum has not yet become prominent on the New England landscape. However, it has the potential to form large thickets that would suppress the growth of native shrubs and herbaceous plants. More information is necessary to assess the status of this species in this region.
