Leaves
The petiole is short, 1.5 to 4.1 mm, and half-clasps the stem. The blade is elliptic, broadly elliptic or ovate, 3.6 to 12.3 cm long and 2.1 to 7.7 cm wide, finely toothed; the white hairs on the main and lateral veins beneath mostly fall off at maturity.
Flowers
In April to May, 1 to 2 flowers are borne at the tips of one-year-old twigs and in the leaf axils. The funnel-shaped corolla changes from pale yellow-green to red, with yellow guide lines inside.
Fruit
The cylindrical capsule is 1.9 to 2.3 cm long and ripens blackish purple to black in September to October. It splits in two to scatter the seeds, but the husk remains until spring. Seeds are cylindrical rhombic, 0.8 to 1.2 mm long.
Bark
Old bark is dark gray-brown with coarse lengthwise wrinkles; two-year-old twigs are purple and smooth with oval lenticels.
