Thuja Occidentalis Plant Named Triple G Tree

Abstract

A distinct Thuja occidentalis cultivar having a shorter maximum height at maturity with a less elongate crown, more piriform shape, and overall bright green coloration all year round. The branchiets are slightly curved and ascend in more compacted sprays requiring less trimming to maintain shape.

Claims

1. A new and distinct Thuja occidentalis cultivar substantially as shown and described and particularly characterized by a more compact growth, smaller mature height, less elongated crown, more piriform shape, and a more vibrant bright green coloration all year round, with slight curling of the branchlets.

DETAILED BOTANICAL DESCRIPTION

[0010] The following traits have been repeatedly observed and are believed to be characteristics of the Triple G cultivar. The below observations, measurements and values describe the new cultivar as grown in North Carolina and distinguish this arborvitae as a new and distinct cultivar. [0011] Type: Native, perennial conifer tree of the Cupressaceae family. [0012] Appearance: Grows to a maximum height of 7 to 10 meters at maturity. The crown is narrowly conic and less pyramidal than other Thuja cultivars. Densely crowded branches with flattened branchlets are slightly curled into tautly arrayed, fan-shaped sprays. [0013] Origin: Propagated from cuttings collected from a variant specimen discovered in a commercial stand of Thuja occidental L. in Lenoir, N.C. [0014] Parentage: Variant cultivar discovered in a cultivated area. [0015] Classification: Thuja occidentalis L. cultivar Triple G. [0016] Height: Shorter and more compact that other Thuja occidentalis cultivars. Maximum height at maturity tops out under 10 meters. [0017] Leaves: Small flattened, green twigs bearing paired, evergreen, scale-like decussate leaves, approximately 2 to 3 mm long and abruptly pointed. Tips are blunt to sharply pointed and slanted toward the sprout. Surface leaves have a broad keel that narrows sharply at the tip. Marginal leaves scaffold pressed against the flanks of the surface leaves or the keels of the next higher marginal leaves. [0018] Branchlets: Flattened, bright green on the upper side and pale green on the base. Perceptibly lighter green than other Thuja cultivars, and slightly curled. Do not turn yellow-brown in winter like other Thuja cultivars. [0019] Odor: Camphoraceous. [0020] Bark: Gray to reddish-brown, 6 to 9 mm thick, fibrous, separated into flat, connected ridges. [0021] Seeds: Seed cones are ellipsoid 6 to 14 mm long, brown. Seeds ca. 8 per cone, 4 to 7 mm long, with lateral wings about as wide as the body.
