Lonicera japonica
Japanese honeysuckle LOJA
Form: Trailing or climbing vine up to 80 ft (25 m) long. Young
stems finely pubescent; older stems reddish-brown and the
bark sometimes shredding.
Leaves: Opposite, mostly ovate, apex with an abrupt tooth
or cusp; margins entire, but can be lobed in early spring;
undersides appear whitish. Semi-evergreen.
Flowers/fruit: Axillary pairs on a bracted stalk. Flowers white
to pale cream. Corolla tube approximately equals the lobes.
Blooms in springtime. Fruit a black berry.
Habitat: Disturbed woods, fields, thickets, and forest edges.
Other distinguishing features/notes: This looks similar to
the native vine Lonicera hirsuta (hairy honeysuckle) when not
in flower. However, once L. hirsuta begins flowering, it forms
distinctive connate terminal leaves. If not in flower yet, check
the site condition. L. japonica will be found on disturbed
sites. If berries are present, L. hirsuta has red ones.
