Ulmus 'Columella'
Elm 'Columella'
Elms are deciduous or semi-deciduous trees. 'Columella' was bred because it is resistant to Dutch elm disease. It has a slender, fairly open, columnar crown, and leaves that emerge quite late, and are dark green, oval - narrower at the base, - 6 - 10 cm and scalloped.The foliage turns yellow in Autumn. The bark is silvery-grey and smooth, becoming dark grey with black grooves. Long-stalked bundles of light green flowers appear in early Spring, and are followed by flat winged brown nutlets that are round to elliptical. This tree is used mainly for lining roads and avenues, and in public spaces, such as parks

Planting
From Early Spring TO Early Spring
Trees which have a trunk less than about two inches in diameter often require staking and some early pruning to prevent leaning and blowover due to a heavy crown and unstable root system.
Propagation
From Early Spring TO Late Autumn
Propagation is by seed, summer cuttings, or grafts.
