Ulmus 'Rebona'


Ulmus 'Rebona' is an American hybrid cultivar raised by the Wisconsin Alumni Research Foundation as selection 'W916', derived from a crossing of Japanese Elm clone W43-8 = 'Reseda' with Siberian Elm clone W426 grown from seed collected from a street tree at Yankton, South Dakota. The tree was registered in 1993 by Conrad Appel KG, of Darmstadt and is a sibling of 'New Horizon'. In Europe, 'Rebona' is marketed as a Resista elm protected under E U breeders' rights.

Description

'Rebona' bears a close resemblance to its sibling 'New Horizon', but requires less maintenance owing to a better leader. The tree grows rapidly, developing a fastigiate pyramidal shape with ascending branches. The glossy clear-green leaves are comparatively small, though slightly larger than those of 'New Horizon'.

Pests and diseases

'Rebona' is highly resistant to Dutch elm disease, rated 5 out of 5.

Cultivation

'Rebona' has been widely planted as a street tree in Germany, the Netherlands, and to a lesser extent in France and the UK.
