USPP36524P2 - Chionanthus tree named ‘CVJMW’ - Google Patents

Abstract

A new cultivar of Chionanthus virginicus tree named ‘CVJMW’ that is characterized by its prolific flowering; even as a young plant, its foliage that is dark green in color, its upright branching habit, its upright-oval form, and its vigorous growth rate.

Description

Botanical classification: Chionanthus virginicus.

Variety denomination: ‘CVJMW’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chionanthus virginicus and will be referred to hereafter by its cultivar name, ‘CVJMW’. ‘CVJMW’ is a new fringetree tree grown for use as a landscape plant.

‘CVJMW’ was discovered by the Inventor as a chance seedling that was growing in a field plot planted with over 200 unnamed and unpatented plants of Chionanthus virginicus in Iva, South Carolina in June of 2021. The exact parentage is therefore unknown.

Asexual propagation of the new cultivar was first accomplished under the direction of the Inventor using stem cuttings in June 2021 in Rutledge, Georgia. 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 observed repeatedly and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘CVJMW’ as a unique cultivar of Chionanthus.

• • 1. ‘CVJMW’ exhibits prolific flowering, even as a young plant.
  • 2. ‘CVJMW’ exhibits a compact plant habit with a dense canopy.
  • 3. ‘CVJMW’ exhibits foliage that is dark green in color.
  • 4. ‘CVJMW’ exhibits an upright branching habit.
  • 5. ‘CVJMW’ exhibits an upright-oval form.
  • 6. ‘CVJMW’ exhibits vigorous growth rate.

Plants of the species Chionanthus virginicus that were growing in the plot where the claimed plant was discovered, all differ from ‘CVJMW’ in having less vigorous growth habits, lighter colored foliage, less upright branch angles, and a less dense and less compact plant habit. ‘CVJMW’ can be most closely compared to the Chionanthus virginicus cultivars ‘CVSTF’ (Not Patented) and ‘CV1049’ (Not Patented). ‘CVSTF’ and ‘CV1049’ are both similar to ‘CVJMW’ in having a dense canopy and foliage that is dark green in color. ‘CVSTF’ differs from ‘CVJMW’ in having wider branch angles, a broader plant habit and leaves that are slightly longer and more broad. ‘CV1049’ differs from ‘CVJMW’ in having much wider branch angles, a rounded plant form and leaves that are wider.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new cultivar of Chionanthus.

The photograph is FIG. 1 provides a view of ‘CVJMW’ in bloom.

The photograph in FIG. 2 provides a close up view of the flowers.

The plant in the photograph in FIG. 3 was taken of the 3-year-old tree originally grown in Iva, South Carolina showing a view of the foliage.

The photograph in FIG. 4 was taken of a plant about 9 months in age as grown outdoors in a 3-gallon container in Rutledge, Georgia and provides a view of the plant in flower at a very early age when grown in a container.

The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Chionanthus.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of plants of the new cultivar grown outdoors in field production (3-years in age) and 3-gallon containers (9-months in age) in Rutledge, Georgia with other data collected from a plant about 5 years in age as grown in the ground in Rutledge, Georgia. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2001 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
