plant named ‘Bronfire’

Abstract

A new cultivar of Cotoneaster named ‘Bronfire’, characterized by its foliage that is dark green in color that changes to orange and red in color in the fall, its foliage that is glossy, cup-shaped and slightly twisted, its mid to late summer berries that are bright red in color, its upright pant habit and its cold hardiness at least to U.S.D.A. Zone 3.

Description

Botanical classification: Cotoneaster hybrid.

Cultivar designation: ‘Bronfire’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Cotoneaster plant of hybrid origin, botanically known as Cotoneaster ‘Bronfire’, and will be referred to hereafter by its cultivar name, ‘Bronfire’. ‘Bronfire’ is a new cultivar of deciduous shrub grown for use as a landscape plant.

The new cultivar originated as a chance seedling growing in a container during production at a nursery in Grand Forks, B. C, Canada in summer of 2010. The container originated from seed planted from an unnamed and unpatented plant of Cotoneaster lucidus. The male parent is unknown, however it is thought to be a plant of Cotoneaster apiculatas based on the characteristic of the new cultivar.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings in Grand Forks, British Columbia, Canada in 2011 by the Inventor. Asexual propagation by softwood 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 ‘Bronfire’. These attributes in combination distinguish ‘Bronfire’ as a new and distinct cultivar of Cotoneaster.

• • 1. ‘Bronfire’ exhibits foliage that is intense dark green in color that changes to orange and red in color in the fall.
  • 2. ‘Bronfire’ exhibits foliage that is glossy, cup-shaped and slightly twisted.
  • 3. ‘Bronfire’ exhibits mid to late summer berries that are bright red in color.
  • 4. ‘Bronfire’ exhibits blooms that are pink-white in color in late spring.
  • 5. ‘Bronfire’ exhibits an upright plant habit.
  • 6. ‘Bronfire’ exhibits cold hardiness at least to U.S.D.A. Zone 3.

The female parent plant is similar to ‘Bronfire’ in having an upright plant habit. The female parent differs from ‘Bronfire’ in having berries that are black in color and foliage that is lighter in color and flat in aspect. ‘Bronfire’ can be most closely compared to typical plants of Cotoneaster apiculatus (and probably species of the male parent). Typical plants of Cotoneaster apiculatus are similar to ‘Bronfire’ in having berries that are red in color and glossy foliage. Cotoneaster apiculatus differs from ‘Bronfire’ in having foliage that is smaller in size and in having a spreading plant habit. ‘Bronfire’ can also be compared to the Cotoneaster cultivar ‘Tom Thumb’ (not patented). ‘Tom Thumb’ differs from ‘Bronfire’ in being a groundcover type Cotoneaster. There are no known cultivars known to the Inventor of a hybrid between Cotoneaster lucidus and Cotoneaster apiculatus.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrates the overall appearance and distinct characteristics of the new Cotoneaster. The photographs were taken of plants 3 years in age as grown outdoors in Grand Forks, British Columbia, Canada.

The photograph in FIG. 1 provides a close up view of the foliage turning in fall of ‘Bronfire’.

The photograph in FIG. 2 provides a view of the berries of ‘Bronfire’.

The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description accurately describe the new Cotoneaster.
