USPP34661P2 - Gaultheria plant named ‘Gaulsidh4’ - Google Patents

Abstract

A new cultivar of Gautheria shallon plant named ‘Gaulsidh4’ that is characterized by its leaves that are small in size and ovate to round in shape, its very compact plant habit, and its floriferous blooming habit.

Description

Botanical classification: Gaultheria shallon.

Cultivar designation: ‘Gaulsidh4’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to a Canadian Plant Breeder's Rights Application No. 21-10462 filed on Apr. 15, 2021, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein. This application is also co-pending with a U.S. Plant Patent Application filed for a plant derived from the same breeding program that is entitled Gaultheria Plant Named ‘Gaulsidh12’ (U.S. Plant patent application Ser. No. 17/701,052).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gaultheria shallon, botanically known as Gaultheria shallon ‘Gaulsidh4’ and is hereinafter referred to by its cultivar name ‘Gaulsidh4’.

‘Gaulsidh4’ was discovered by the Inventor as a chance seedling that was growing in a container in Mission, B.C., Canada in spring of 2014. The containers had been planted with seed derived from unnamed and unpatented plants of Gaultheria shallon. The exact parents are unknown.

Asexual propagation of the new cultivar was first accomplished by tissue culture using meristemac tissue under the direction of the Inventor in Mission, B.C., Canada in spring of 2015. Asexual propagation of the new cultivar by tissue culture has shown that the unique features are stable and 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 ‘Gaulsidh4’ as a new and unique cultivar of Gaultheria.

• • 1. ‘Gaulsidh4’ exhibits leaves that are small in size and ovate to round in shape.
  • 2. ‘Gaulsidh4’ exhibits a very compact plant habit.
  • 3. ‘Gaulsidh4’ exhibits a floriferous blooming habit.

‘Gaulsidh4’ can be most closely compared to a typical unnamed plant of Gaultheria shallon and ‘Gaulsidh12’. Both are similar to ‘Gaulsidh4’ in flower color. The unnamed Gaultheria shallon differs from ‘Gaulsidh4’ in having a much larger plant size and in being less floriferous. ‘Gaulsidh12’ differs from ‘Gaulsidh4’ in having a larger plant size, a less compact plant size, new growth that is red in color, leaves that are more narrow and pointed in shape, and in being less floriferous.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of two year-old plants as grown outdoors in 1-gallon containers in St. Thomas, Ontario, Canada.

The photograph in FIG. 1 provides a side view of the plant habit of ‘Gaulsidh4’.

The photograph in FIG. 2 provides a side view of ‘Gaulsidh4’ in bloom.

The photograph in FIG. 3 provides a close-up view of the flowers of ‘Gaulsidh4’.

The photograph in FIG. 4 provides a comparison view between ‘Gaulsidh12’ (left) and ‘Gaulsidh4’ (right).

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 Gaultheria.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of 2.5-year-old plants of the new cultivar grown outdoors in 1-gallon containers in St. Thomas, Ontario, Canada.
