USPP37251P2 - Cornus plant named ‘Elsie Red’ - Google Patents

Abstract

A new cultivar of Cornus florida plant named ‘Elsie Red’ that is characterized by its flowers that are bright red-pink in color (bracts) with yellow centers, its rapid growth habit, its good resistance to powdery mildew, and its flowers that are sturdy and have a high tolerance to wind.

Description

Botanical classification: Cornus florida.

Variety denomination: ‘Elsie Red’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Cornus florida plant and will be referred to hereafter by its cultivar name, ‘Elsie Red’. ‘Elsie Red’ is a new cultivar of dogwood, a shrub grown for use as an ornamental landscape plant.

The Inventor discovered the new cultivar as a chance seedling growing in a production field at his nursery in Huntland, Tennessee in August of 2017. The field had been planted with seed from unnamed and unpatented plants of Cornus florida.

Asexual propagation of the new cultivar was first accomplished by the Inventor using budding onto seedlings (not patented) of Cornus florida in August of 2017 in Huntland, Tennessee. Asexual propagation of the new cultivar by budding has determined that the characteristics are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘Elsie Red’ as a unique cultivar of Cornus.

• • 1. ‘Elsie Red’ exhibits flowers that are bright red-pink in color (bracts) with yellow centers.
  • 2. ‘Elsie Red’ exhibits good branching with a strong central leader.
  • 3. ‘Elsie Red’ exhibits a rapid growth habit.
  • 4. ‘Elsie Red’ exhibits good resistance to powdery mildew.
  • 5. ‘Elsie Red’ flowers that are sturdy and have a high tolerance to wind.

The probable female and male parents of ‘Elsie Red’ differ from ‘Elsie Red’ in having white color flowers as all the plants in the production field had white flowers. ‘Elsie Red’ can be most closely compared to the cultivars of Cornus florida ‘JN13’ (U.S. Plant Pat. No. 29,424) and ‘Comco No. 1’ (U.S. Plant Pat. No. 10,166). ‘JN13’ is similar to ‘Elsie Red’ in having red color flowers (bracts). ‘JN13’ differs from ‘Elsie Red’ in having flowers (bracts) that are more burgundy and less bright in color and less sturdy so prone to shattering in the wind, and branches and central leader that are weaker. ‘Comco No. 1’ is similar to ‘Elsie Red’ in having red color flowers (bracts) and a rapid growth habit. ‘Comco No. 1’ differs from ‘Elsie Red’ in having flowers (bracts) that are lighter red in color and less sturdy so prone to shattering in the wind.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Cornus. The photographs were taken of a three year-old plant as grown in a trial field in Huntland, Tennessee.

The photograph in FIG. 1 provides a side view of a plant of ‘Elsie Red’ in bloom.

The photograph in FIG. 2 provides a close-up view of flowers of ‘Elsie Red’.

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 Cornus.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of three year-old plants of the new Cornus as grown in 10-gallon containers in Huntland, Tennessee. 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 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
