Somewhat variable width, large shrub to medium-size tree with a broad pyramidal to oval crown that grows to 10 to 15 m. Young twigs yellow-brown to brown, older bark dark grey, slightly grooved when mature to reveal orange bast. The leaves are vary greatly in shape and size. From oval to elongated-ovate or diamond-shaped and 3 - 11 cm long. They are glossy green and scarcely change colour in autumn. The flowers hang in racemes from short lateral branches and open in June and July. They are 1.5 to 2.5 cm and white with yellow stamens. They have a strong, pleasant fragrance. This species blossoms very richly and is therefore very bee friendly. The flowers are followed by hard, ovoid grey-green drupes with a dark green calyx. A graceful park tree with a rich inflorescence.
