Abstract

A new cultivar of Rosa named ‘TMRO14-08’ that is distinguishable by a semi-prostrate plant habit, small glossy green compound leaves, and lightly fragrant semi-double flowers which open pale pink in color with darker pink centers. The pink color of the early flowers soon gives way to pure white flowers with occasional tinges of very pale pink. ‘TMRO14-08’ bears glossy red hips when mature and is hardy in USDA Hardiness Zone 5. In combination, these traits set ‘TMRO14-08’ apart from all other existing varieties of Rosa known to the inventor.

Description

Genus and species: Rosa x hybrida.

Denomination: ‘TMRO14-08’.

BACKGROUND

The present invention comprises a new and distinct variety of rose, botanically known as Rosa x hybrida and hereinafter referred to by the variety name ‘TMRO14-08’. The new variety of rose plant originated from an open pollination carried out by the inventor at the inventor's nursery in Ipswich, United Kingdom in 2011. The female parent is the inventor's proprietary variety known by code ‘RO13197W’ (unreleased, unpatented), and the male parent is an unknown proprietary variety from the inventor's collection of rose seedlings. Seeds collected from the female parent were sown, grown and planted in the field for evaluation.

The inventor selected and first propagated the new rose plant ‘TMRO14-08’ in 2014 in Ipswich, United Kingdom via softwood cuttings and has confirmed that ‘TMRO14-08’ reproduces true to type in successive generations of asexual propagation via softwood cuttings.

SUMMARY OF THE INVENTION

The following are the distinguishing characteristics of the new variety ‘TMRO14-08’ when grown under normal horticultural practices.

1. ‘TMRO14-08’ exhibits a semi-prostrate plant habit with pendulous branches when grown in containers.
2. ‘TMRO14-08’ bears small glossy green compound leaves.
3. The flowers of ‘TMRO14-08’ are semi-double.
4. Both surfaces of the inner petals of the flowers of ‘TMRO14-08’ are pale pink in color as the flower unfurls. The pink coloration disappears as the petals become pure white in color throughout as the flower fully opens and expands. The inner petals remain to present as pink colored centers to the fully open flowers. The inner petals bear a pink-colored basal spot.
5. The flowers of ‘TMRO14-08’ are self-cleaning.
6. ‘TMRO14-08’ bears glossy red hips when mature.
7. The flowers of ‘TMRO14-08’ are pleasantly fragrant.
8. ‘TMRO14-08’ is hardy in USDA Hardiness Zone 5.

These traits in combination distinguish ‘TMRO14-08’ from all other existing varieties of Rosa known to the inventor. ‘TMRO14-08’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, without any variance in genotype.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall growth and flowering habit of ‘TMRO14-08’ at 24 months growing out of doors in Santa Barbara, California in a 20 cm. diameter container.

The photograph was made using conventional techniques and although flower and foliage color may appear different from actual color due to light reflectance, they are as accurate as possible by conventional photography. Colors in the photograph may differ slightly from the color values cited in the description, which accurately describes the observed colors of ‘TMRO14-08’.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of the new Rosa cultivar named ‘TMRO14-08’. Observations and measurements were collected in August 2022 in Santa Barbara, California from a two year old plant growing outdoors in a 2-gallon container. Color determinations were made in accordance with The 2007 Royal Horticultural Society Colour Chart from London England, except where general color terms of ordinary dictionary significance are used. Growing requirements are similar to the species.
