Ulmus x 'Frontier'

Frontier Elm

Frontier elm is distinguished by long-lasting burgundy autumn foliage. Its glossy green summer leaves sit on a vase-shaped to oval crown, bringing a different fall palette to a mixed shade-tree planting.

The canopy loses its leaves for winter. Autumn color includes burgundy. 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.
