Cultivar 'Ornata'
Origin France

The European White Elm Ulmus laevis cultivar 'Ornata' was erroneously identified by Carrière as U. communis (: glabra) ornata in Revue Hort. 554, 1858.

Description

The name Ornata was given to trees whose leaves were not eaten by insects. It was said to be a vigorous strain with dark green leaves and the tree had a regular shape, particularly suitable for street planting.

Cultivation

Two trees growing on the Grand-Rond in Toulouse were reported by Mlle. Y. de Ferre, to be still alive in 1964, and were noted for their resistance to insect attack. While the leaves of most trees in the area were eaten to a skeleton, the ones of 'Ornata' remained unaffected. [1]. Seed propagated plants largely kept their resistance to insect attack. 'Ornata' is not known to remain in cultivation elsewhere.
