Ulmus 'Rebona'®

Ulmus 'Rebona'®

Rebona Elm

Description

Ulmus 'Rebona' (Rebona elm) originates from exactly the same sowing as Ulmus 'New Horizon' and consequently belongs to the newest generation of Resista® Elms: the crossing of Ulmus japonica with Ulmus pumila from the breeding programme of professor Smalley and professor Guries of Madison University, Wisconsin Alumni Research Foundation, United States. ‘Rebona’ was released in 1994 following on from this programme. Ulmus 'Rebona' grows quickly with an upright main trunk, has a pyramidal, densely branched crown and becomes a medium size to large tree, approximately fifteen to twenty metres tall. 

The glossy leaf of Ulmus ‘Rebona’ is slightly darker green and smaller than that of Ulmus 'New Horizon'. In the spring it emerges light green and in late autumn it turns the most beautiful warm yellow hues. Rebona elm has a striking, violet blossom produced in small quantities - as well as the characteristic elm seeds which follow. The selection develops a heavy trunk with light grey bark and orange underbark, and in older trees vertical serrations form.

This very wind-resistant tree - as well as having good resistance to Dutch elm disease - also has excellent resistance to road salt, frost, verticillium, drought and brief flooding. This makes it a very strong and healthy tree for various soil types and the urban climate, where it can be used in streets, avenues and on squares but also as an attractive, large landscape tree. Ulmus ‘Rebona’ and Ulmus ‘New Horizon’ share so many similarities that - for the sake of diversity - they can be planted in combination without looking out of place.
