Description

Latin name of the genus and species: Hibiscus syriacus.

Variety denomination: ‘GFNHSRP’.

BACKGROUND OF THE INVENTION

The new Hibiscus cultivar is a product of a naturally occurring branch mutation of the variety Hibiscus syriacus ‘Gandini van Aart’, U.S. Plant Pat. No. 28,892. The new cultivar was found and selected by the inventor in the summer of 2018 in Stone County, Miss.

Asexual reproduction of the new cultivar ‘GFNHSRP’ was first performed in the summer of 2019 in Stone County, Miss., by softwood cuttings. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

Date of first sale was Jun. 21, 2022, occurring in Grand Haven, Mich. This sale was made directly by the inventor or one who obtained the claimed invention directly or indirectly from the inventor. This sale and all public disclosures made between Jun. 21, 2022, and the filing of this application fall within the exception allowed under 102(b)(1).

SUMMARY OF THE INVENTION

The cultivar ‘GFNHSRP’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘GFNHSRP’. These characteristics in combination distinguish ‘GFNHSRP’ as a new and distinct Hibiscus cultivar:

    • 1. Reddish-pink colored flowers with a large, deep red “eye”.
    • 2. “Eye” of flower extends to around 50% of each petal surface.
    • 3. Upright and columnar/narrow habit.

PARENT COMPARISON

Plants of the new cultivar ‘GFNHSRP’ are similar to the seed parent Hibiscus ‘Gandini van Aart’, in most horticultural characteristics. However, characteristics of the new cultivar differ in the following:

    • 1. Flowers of the new variety are reddish-pink with a large, deep red “eye”. Flowers of the seed parent are pure white.

COMMERCIAL COMPARISON

Plants of ‘GFNHSRP’ are similar in some horticultural characteristics to the variety Hibiscus ‘Gandini Santiago’, U.S. Plant Pat. No. 25,568. The new variety, however, differs in the following:

    • 1. Flowers of the new variety are darker reddish-pink with a large, deep red “eye”. Flowers of this comparator are lighter, purplish-pink with a large, deep-red “eye.”

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘GFNHSRP’ grown outdoors at a commercial nursery in Grand Haven, Mich. This plant is approximately 3 years old, shown in a 3-gallon container.

FIG. 2 illustrates a closer view of the flowers.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
