USPP36690P2 - Cotoneaster plant named ‘MONSHGUS’ - Google Patents

Abstract

A new and distinct variety of Cotoneaster plant named ‘MONSHGUS’ is disclosed, characterized by a very narrow, upright plant form with dense growth. Plants of ‘MONSHGUS’ have been observed to have a mature size of 5 feet tall and 2 to 3 feet wide. The new variety is suitable for use as a hedge and can be sheared into formal shapes. The foliage is small and dense, creating a fine textured appearance. The new cultivar is a Cotoneaster, suitable for horticultural purposes.

Description

Latin name of the genus and species: Cotoneaster hybrid.

Variety denomination: ‘MONSHGUS’.

BACKGROUND OF THE INVENTION

The new cultivar, hereinafter referred to as ‘MONSHGUS’, was discovered as part of a breeding program at a commercial nursery in Dayton, OR. The intention of the breeding program was to develop new Cotoneaster varieties with novel plant habits for commercial ornamental purposes. This new discovery is the result of an open pollination of various unpatented Cotoneaster varieties of different species conducted by the inventor during 2019.

‘MONSHGUS’ was selected as a seedling in June of 2021 at the same commercial nursery in Dayton, Oregon. After identifying the new variety as a potentially interesting selection, the inventor first organized propagation of ‘MONSHGUS’ by softwood cuttings at the same commercial nursery during the June of 2021. The inventor continued controlled testing and propagation, assessing stability of the unique characteristics of this variety. At least seven generations have been reproduced and have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘MONSHGUS’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘MONSHGUS’ These characteristics in combination distinguish ‘MONSHGUS’ as a new and distinct Cotoneaster cultivar:

• • 1. This is a hedge-type Cotoneaster that can be sheared into formal shapes.
  • 2. Plant habit is upright and stays narrow, growing 5′ tall and 2-3′ wide.
  • 3. Fine textured with small, 0.5-1 cm, circular leaves and dense foliage.

COMPARISON TO PARENT VARIETY

The exact parent varieties cannot be identified.

COMMERCIAL COMPARISON

Cotoneaster ‘MONSHGUS’ can be compared to the commercial variety Cotoneaster lucidus unpatented. Plants are similar in most horticultural characteristics; however, plants of the new variety differ in the following:

• • 1. The new variety has 0.5-1 cm, circular leaves that are bright green and glossy; Cotoneaster lucidus has dull green elliptic to ovate leaves which are 2.5 cm to 6 cm long and 2.5 cm wide.
  • 2. The new variety has an upright, dense branching habit; Cotoneaster lucidus has long, spreading branches.
  • 3. The new variety is fine textured; Cotoneaster lucidus is medium textured.
  • 4. Plant size of new variety is 5′ tall and 2-3′ wide. Plant size of Cotoneaster lucidus is 6-10′ tall and 6-10′ wide.

Cotoneaster ‘MONSHGUS’ can be compared to the unnamed commercial variety Cotoneaster franchetii unpatented. Plants are similar in most horticultural characteristics; however, plants of the new variety differ in the following:

• • 1. The new variety has an upright habit with stiff branches; Cotoneaster franchetii has sweeping/arching growth.
  • 2. The new variety has 0.5-1 cm, circular leaves that are bright green and glossy; Leaves of Cotoneaster franchetii are roughly 2.5 cm long and 1.5 cm wide, elliptic, and pubescent on the undersides.
  • 3. New variety takes well to shearing into formal shapes and keeps tidy appearance; Cotoneaster franchetii can tolerate a light prune/shearing before losing its graceful appearance.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate in full color a typical plant of ‘MONSHGUS’ grown outdoors in Dayton, OR.

FIG. 1 is a plant of ‘MONSHGUS’ which has been sheared. The plant is approximately 1.5 years old, in a 2-gallon pot which has been sheared.

FIG. 2 illustrates the dense foliage. Photos were taken during the Spring and illustrate new growth and young foliage.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
