Difference Between Viburnum and Hydrangea

1. Difference of blades

The leaves of Viburnum are papery, broadly obovate, broadly ovate or obovate, about 3-10 cm long, with an acute apex, a rounded to slightly cordate or obtuse base, sometimes cuneate, with tooth-like serrations on the edges, with sharper tooth tips, hairy above and below, with the densest hairs on the veins, and with yellow or nearly colorless glandular dots, and a short petiole, about 10-15 mm long.

The leaves of hydrangea are nearly leathery or papery, obovate or broadly elliptic, larger and wider than the former, about 6-15 cm long and 4-11.5 cm wide, with a sharp tip and a pointed end, a broad cuneate or obtuse base, and coarse teeth on the edges from the base upwards, glabrous on both sides or only with short soft hairs on the midrib below, and a relatively thick petiole, about 1-3.5 cm long.

2. The difference between flowers

Viburnum has a compound cyme inflorescence and the flowers are white.

Hydrangea has corymbose inflorescences with a variety of colors, usually pink, white or light blue.
