Form: Deciduous, upright, arching-branched shrub up to 16
ft (5 m) tall. Twigs densely pubescent and typically hollow.

Blades elliptic to ovate to somewhat lanceolate, acuminate,

Flowers/fruit: Flowers paired, in leaf axils. White, turning
yellow with age, outer surface of corolla usually glabrous;

the shrubby native forms of Lonicera have white solid pith.
The nonnative forms have dark, usually hollow pith. In the
NRS region, the most commonly encountered nonnative
