Abstract

A new cultivar of Rosa plant named ‘Elizabeth Ashley’ that is characterized by its compact, upright, and uniform plant habit, its double flowers that are bi-colored with yellow-orange and dark red-pink petals, its glossy and disease-free foliage, and its continuous and prolific blooming habit.

Description

Botanical classification: Rosa hybrid.

Variety denomination: ‘Elizabeth Ashley’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Rosa hybrid. The new cultivar will be referred to hereafter by its cultivar name, ‘Elizabeth Ashley’. ‘Elizabeth Ashley’ is a new cultivar of hybrid tea rose grown for use as a container and landscape plant.

‘Elizabeth Ashley’ was derived from controlled crosses made in May of 2011 in Klazienaveen, The Netherlands between unnamed and unpatented Rosa plants from the Inventor's breeding program as both the male and female parents. Seeds were pooled from various crosses and therefore the exact parent plants are unknown. ‘Elizabeth Ashley’ was selected in January of 2012 as a single unique plant amongst the resulting seedlings from the above crosses.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings by one of the Inventors in October of 2012 in Klazienaveen, The Netherlands. Asexual propagation by softwood stem cuttings has determined that the characteristics of this cultivar 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 ‘Elizabeth Ashley’ as a unique cultivar of Rosa.

1. ‘Elizabeth Ashley’ exhibits a compact, upright and uniform plant habit.
2. ‘Elizabeth Ashley’ exhibits double flowers that are bi-colored with yellow-orange and dark red-pink petals.
3. ‘Elizabeth Ashley’ exhibits glossy foliage.
4. ‘Elizabeth Ashley’ exhibits disease free foliage.
5. ‘Elizabeth Ashley’ exhibits a continuous and prolific blooming habit.

‘Elizabeth Ashley’ can also be compared to the Rosa cultivars ‘BAIpeace’ (U.S. Plant Pat. No. 14,731), ‘WEKdocpot’ (U.S. Plant Pat. No. 20,633), and ‘Mein München’ (not patented). All are similar to ‘Elizabeth Ashley’ in flower coloration. ‘BAIpeace’ differs from ‘Elizabeth Ashley’ in having a taller plant height, in having leaves that are less glossy, in having flower buds that are larger in size and in producing less flowers. ‘WEKdocpot’ differs from ‘Elizabeth Ashley’ in having larger flowers. ‘Mein München’ differs from ‘Elizabeth Ashley’ in having flowers with fewer and larger flower buds, deeper flower coloration and in having a less compact plant habit.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Rosa. The photographs were taken of a two-year-old plant of ‘Elizabeth Ashley’ as grown in a greenhouse in a 2-gallon container Klazienaveen, The Netherlands.

The photograph in FIG. 1 provides a side view of a plant of ‘Elizabeth Ashley’ in bloom.

The photograph in FIG. 2 provides a close-up view of a newly opened flower of ‘Elizabeth Ashley’.

The photograph in FIG. 3 provides a close-up view of multiple flowers in different maturation stage of ‘Elizabeth Ashley’.

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 Rosa.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of 4-year-old plants of ‘Elizabeth Ashley’ as grown in a greenhouse in #6 containers in Salem, Oreg.
