Plant	Deciduous shrubs are up to 20′ (6 m) in size. Mature stems contain a hollow white or tan pith. Bark is deeply fissured and exfoliating, often peeling.	Shrubs are 3–9½′ (1–3 m) around.	A vine up to 16′ (5 m) in size. Young stems are reddish- or light-brown, while older stems are hollow, with peeling bark
Leaves	Opposite, medium to dark green, ⅞–3½ ⨉ ¾–1½″ (2.5–9 ⨉ 2–4 cm), lanceolate to ovate, with smooth edges and at least some rough-feeling hairs.	Opposite, elliptic to broad-ovate, with smooth edges. They are ⅞–3″ (2.5–7.5 cm) long, and dull blue-green to dark green.	Opposite, roughly oval-shaped, with smooth edges. Younger leaves may have lobes.
Flowers	Fragrant white flowers, aging to yellow or pale orange in color, occur in pairs. Flowers have two lips and are about 1″ (2.5 cm) in size. They appear from May to June.	Blooms are a creamy white color, in pairs, appearing in March-April, and very fragrant, with a lemony smell. Each flower is ⅜″ (1 cm) in size.	Flowers are white, showy, fragrant, about 1″ (2.5 cm) in size. They fade to a yellow color, so the vine appears to have white and yellow flowers
Fruit	Bright red to black, translucent berries are 1/16–⅛″ (2–6 mm) in size. Each berry contains multiple seeds.	Orange to red berries ⅛–¼″ (6–8 mm) around.	Black, about ⅛″ (3.2 mm) around.
Range/ Zones	USDA Zones: 3-8	USDA Zones: 4-8	USDA Zones: 5a-8b
Habitats	Anthropogenic habitats, i.e. those disturbed or modified by man, such as roadsides and railroads, woodland borders, some forests, fields, unused or disturbed lands and yard edges..	Woodlands, fields, and most disturbed sites.	Disturbed areas, such as roadsides and floodplains. It spreads more slowly in forested areas.

Plant	Deciduous shrubs are 6½–8′ (2–2.5 m) in size. Stems are hollow.	Densely branched shrub, up to 10–12′ (3–3.7 m) around
Leaves	Opposite, simple, narrowly ovate to oblong-elliptic. They are ⅞–1¾″ (2.5–5 cm) long, have blunt or pointed tips, with hairy undersides.	Leaves are oval in shape, with smooth edges and a bluish cast, 1½–2½″ (3.8–6.3 cm) long × 1–1½″ (2.5–3.8 cm) wide, in opposite pairs
Flowers	Yellow, white, or sometimes pink flowers occur along leaf axils, in pairs. Each flower is ¾–1″ (1.9–2.5 cm) long, with a thin tube and two lips. The upper lip has four erect lobes, and the lower lip bends downward. Surfaces are hairy, especially the tube. There are five yellow-tipped stamens, and a white style, with a green, dome-shaped stigma.	Pairs of flowers, each about ¾″ (1.9 cm) around, may be white, pink, or rose. Each flower has five spatula-shaped, somewhat unruly-looking petals, and five anthers

Range/ Zones	USDA Zones: 4-8	USDA Zones: 3a-8b
Habitats	Anthropogenic (man-made or disturbed habitats), floodplains, forests, or wetland margins.	In the US, it invades thickets, open woodlands, roadsides and fence rows. It prefers moist, loamy soil, with partial sun.
