USPP37069P2 - Paxistima plant named ‘Paxsid1’ - Google Patents

Abstract

A new cultivar of Paxistima plant named ‘Paxsid1’ that is characterized by its bushy, upright habit, its very good branching, and its foliage that is dark green in color.

Description

Botanical classification: Paxistima myrsinites.

Variety denomination: ‘Paxsid1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Paxistima myrsinites and will be referred to hereafter by its cultivar name, ‘Paxsid1’. ‘Paxsid1’ is a new cultivar of Oregon boxwood grown for use as an ornamental landscape plant.

‘Paxsid1’ was discovered by the Inventor as a chance seedling in a trial garden planted with unnamed and unpatented plants of Paxistima myrsinites in Mission, British Columbia, Canada in summer of 2017. The exact parentage is unknown.

Asexual propagation of the new cultivar was first accomplished under the direction of the inventor by stem cuttings in October of 2017 in Mission, British Columbia, Canada. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Paxsid1’ as a unique cultivar of Paxistima.

• • 1. ‘Paxsid1’ exhibits a bushy, upright habit.
  • 2. ‘Paxsid1’ exhibits very good branching.
  • 3. ‘Paxsid1’ exhibits foliage that is dark green in color.

The plants of Paxistima myrsinites that were growing in the area of discovery had plants that were poorly branched and lacked a bushy plant habit. There are no known cultivars of Paxistima myrsinites known to the Inventor.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Paxistima. The photographs were taken of 3-year-old plants as grown in a 2-gallon containers outdoors in a trial plot in St. Thomas, Ontario, Canada.

The photograph in FIG. 1 provides a side view of the plant habit of ‘Paxsid1’.

The photograph in FIG. 2 provides a close-up view of a blooming stem of ‘Paxsid1’.

The photograph in FIG. 3 provides a side view of ‘Paxsid1’ and a typical plant of Paxistima myrsinites.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Paxistima.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of 3-year-old plants as grown in a 2-gallon container outdoors in a trial plot in St. Thomas, Ontario, Canada.
