Abstract
A male green ash tree having a strong central leader, strongly ascending uniformly spaced scaffold branches, uniform crotch angles, and heavy stems, forming an attractive, narrowly oval tree of compact appearance and low pruning requirements; further, the subject tree develops a heavy furrowed protective bark at an early age on the bole and branches progressing from smooth juvenile ash-gray bark slightly tinged with red. Fall foliage color is ephemeral turning to bronze-red with heavy autumn frosts.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinctive variety of Fraxinus pennsylvanica named `Wasky` as described herein and as illustrated, that differs from all other varieties by the unique combination of: (1) strongly ascending branches and a narrow, upright, symmetrical crown that is densely filled with leaves, maintaining a neat appearance; (2) leaves that are dark green, thick and semilustrous above in summer, turning bronze-red for a brief period in autumn; and (3) thick, protective bark that at an early age develops pronounced scaly, flat-topped ridges separated by deep fissures. Flowers show male character and tree produces no seed.
