Ulmus x Triumph

Triumph Elm

Triumph elm (Ulmus 'Morton Glossy') carries dark, glossy foliage on a sturdy, symmetrical framework. The upright oval crown becomes more vase-like as it develops, with yellow leaves in autumn.

The canopy loses its leaves for winter. Autumn color includes yellow. The grower reports tolerance of Dutch elm disease and phloem necrosis.

Choose a sunny position with well-drained soil. Water during establishment and allow enough room for the developing crown.
