Description

Genus and species: Rosa×hybrida.

Variety denomination: ‘ZARsunfrapk’.

BACKGROUND OF THE NEW VARIETY

The present invention comprises a new and distinct variety of rose, botanically known as Rosa×hybrida, and hereinafter referred to by the variety name ‘ZARsunfrapk’. ‘ZARsunfrapk’ originated from a cross conducted in June 2009 in Somis, Calif. between the female rose variety ‘MORsegold’, also commercially known as ‘Sequoia Gold’ (U.S. Plant Pat. No. 6,617), and the male rose variety KNOCK OUT ‘RADrazz’ (U.S. Plant Pat. No. 11,836).

The seeds from the cross were sown and plants were grown for evaluation. An individual plant designated ‘ZARsunfrapk’ was selected in July 2010 in Somis, Calif. ‘ZARsunfrapk’ was first vegetatively propagated in July 2011 in Tipp City, Ohio by softwood cuttings rooted under mist. ‘ZARsunfrapk’ was found to reproduce true to type in successive generations of asexual propagation via softwood cuttings, hardwood cuttings, and by budding onto rootstock.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Somis, Calif., Tipp City, Ohio, Sarasota, Fla., and Grain Valley, Mo.

    • 1. A landscape (miniature) shrub rose having fragrant pink flowers;
    • 2. A compact growth habit requiring little pruning;
    • 3. Easy to root and propagate;
    • 4. Shows resistance to powdery mildew, rust, and black spot;
    • 5. Flowers produce a good color display for an extended period;
    • 6. Grows vigorously on its own roots; and
    • 7. Shown to be heat tolerant and cold hardy in trials, and hardy to USDA Zones 5 to 10.

DESCRIPTION OF THE PHOTOGRAPHS

This new rose plant is illustrated by the accompanying photographs which show the plants' foliage, buds, and flowers. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photos of the plants in FIGS. 1 to 2 were taken outdoors in Grain Valley, Mo. in June 2013, and the plants were 2-years-old. The photo of the plant parts in FIG. 3 was taken in Tipp City, Ohio, in September 2014 from a two-year-old plant.

 DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘ZARsunfrapk’. The data which define these characteristics were collected from asexual reproductions carried out in Tipp City, Ohio between July to October 2014. Data was collected on 2-year-plants, growing on their own roots, outdoors. The plants were not sprayed and were fertilized at a rate of 100 ppm of Nitrogen, Phosphorous, and Potassium. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), (2001).
