Abstract

A new and distinct variety of shrub rose having an upright, compact, and well-branched habit, and yellow flowers, is disclosed.

Description

Genus and species: Rosa hybrida.
Denomination: ‘ZARsunornu’.
BACKGROUND
‘ZARsunornu’ is a new and distinct variety of shrub rose. ‘ZARsunornu’ was observed as a sport branch, naturally-occurring mutation on the parent ‘ZARsunorgdlt’ (U.S. Plant Pat. No. 25,825) in May 2017 in Sarasota, Fla. The sport was propagated by cuttings under midst for several generations to test for stability and performance.
Other subsequent asexual propagations were conducted in controlled environments in Tipp City, Ohio and demonstrate that ‘ZARsunornu’ reproduces true to type in successive generations of asexual reproduction via softwood cuttings, budding, and grafting.
SUMMARY
The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Sarasota, Fla. and Tipp City, Ohio.
    • 1. A shrub rose having an upright, compact, and well-branched habit; and
    • 2. Yellow flowers.
DESCRIPTION OF THE PHOTOGRAPH
This rose plant is illustrated by the accompanying photographs which shows the individual parts of the plant and the whole plant habit. The photographs were taken in Tipp City, Ohio in May 2019 on 18-month-old plants. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.
FIG. 1 shows a whole plant photograph of ‘ZARsunornu’.
FIG. 2 shows from top to bottom, starting at the top (first) row from left to right, a stem with mature and immature leaves, the lower surface of a compound leaf, and the upper surface of a compound leaf; bottom row, from left to right, a part of an individual stem showing thorns, a bud attached to part of a stem, the upper surface of a flower in mid-bloom, the upper surface of a flower in mid bloom, and a flower showing the individual petals and stamens pulled out.
 DETAILED DESCRIPTION
The following detailed descriptions set for the distinctive characteristics of ‘ZARsunornu’. The data which define these characteristics were collected from asexual reproductions carried outdoors in Tipp City, Ohio and Sarasota, Fla. from June 2017 to May 2019 on plants that were two-years-old. The phenotype of this new variety will vary somewhat with variation in environmental, climatic, and cultural conditions as it has not been tested in other environments. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) 2001.
