Brief description

Viburnum rhytidophyllum Hemsl. ex Forbes & Hemsl. is a vigorous, coarsely textured evergreen shrub which has an upright habit and 20 cm long, lustrous, deeply veined oval leaves with dark blue-green surfaces and pale green undersides. Plants grow 3.0–4.6 m tall and wide. The plant is an evergreen shrub or small tree with a suckering habit. Viburnum rhytidophyllum grows naturally in forests and shrubs at altitudes between 700 and 2.400 meters only in some Chinese provinces. It is commonly grown as an ornamental plant for its evergreen foliage and tolerance of deep shade. In countries where the species has been introduced as an ornemental plant, it seems to be spreading more and more near settlements in recent years. It can potentially displace native species and also causes health issues (Wikipedia contributors 2022, Gigon 2012).

Status and distribution in Luxembourg

A specimen of Viburnum rhytidophyllum Hemsl. ex Forbes & Hemsl. from Rumelange can be found in the herbarium of Joseph Witry (25 May 1936). The herbarium of the National Museum of Natural History contains another cultivated specimen from Esch/Alzette (6 June 1959). As of January 2023, most of the occurences documented in the database Recorder-Lux are found in urban areas, in private gardens or parks. But V. rhytidophyllum has also been found in the wild: next to the A.7 in the Grunewald area, in a vineyard near Wellenstein, as well as in forest areas close to Manternach and west of Echternach.
