Firespire American Hornbeam

Firespire American Hornbeam (Carpinus caroliniana 'J.N. Upright')

Firespire American Hornbeam (Carpinus caroliniana 'J.N. Upright') is a narrow, upright cultivar of the native American Hornbeam, selected for its fiery fall color and tight, columnar shape. This refined, space-saving tree is ideal for modern landscapes, tight urban corridors, and anywhere a strong vertical accent is needed.

Distinctive Features

'Firespire' stands out for its unique combination of native adaptability and architectural form. The tree features deep green foliage throughout the growing season that transitions to brilliant shades of orange, red, and scarlet in autumn. Its smooth gray bark and fluted trunk add year-round interest. Unlike the broader native species, this cultivar maintains a slender habit with dense branching and a strong central leader, making it ideal for structured plantings.
