plant named ‘Spinderella’

Abstract

A new and distinct cultivar of winter-hardy, herbaceous, perennial, hybrid Hibiscus plant named ‘Spinderella’ comprising a compact, dense, mounded habit of multiple, well-branched, basal stems producing flowers from the bottom to the top of the plant from late July to frost. Flowers have petals that are broadly-overlapping, with deeply impressed veins of white radiating through the center that intensifies to a medium pink on the leading edge. The foliage is simple and ovate, with a crenulate margin and deep-green with greyed-purple blotches.

Description

Botanical classification: Hibiscus hybrid (L.).

Variety denomination: ‘Spinderella’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(b)(6)

The first non-enabling disclosures were a brief description and photograph of the new plant on Dec. 1, 2019 on the website operated by Walters Gardens, Inc. followed by a listing in the “Walters Gardens 2020-2021 Catalog” that was first distributed on May 20, 2020. The first disclosure, in the form of a sale, was made by Walters Gardens, Inc. on Apr. 13, 2020. Walters Gardens, Inc. obtained the new plant and all information relating thereto, from the inventor. No plants of Hibiscus ‘Spinderella’ have been sold, in this country or anywhere in the world, by any name, nor has any disclosure of the new plant been made more than one year prior the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to the new and distinct hardy, herbaceous, Hibiscus plant, Hibiscus ‘Spinderella’ hybridized under direction of the inventor Aug. 10, 2015 at a wholesale perennial nursery in Zeeland, Mich. The new plant is a cross between the unreleased, proprietary hybrid known as 12-07-1 (not patented) times ‘Vintage Wine’ U.S. Plant Pat. No. 27,839. Into the trial process the new plant was assigned the breeder code labeled 15-66-2. The parent has a complex mixture of species in them, comprising the species: moscheutos and coccineus.

Hibiscus ‘Spinderella’ was first asexually propagated in late summer of 2017 by sterile shoot-tip tissue culture and later by shoot tip cuttings at the same nursery in Zeeland, Mich. The resultant asexually propagated plants have been found to be stable and true to type in successive generations of asexual reproduction.

BRIEF SUMMARY OF THE PLANT

Hibiscus ‘Spinderella’ differs from its parents as well as all other hardy herbaceous Hibiscus known to the applicant in many traits. The most similar Hibiscus cultivars known to the applicant are: ‘Tie Dye’ U.S. Plant Pat. No. 24,078, ‘Starry Starry Night’ U.S. Plant Pat. No. 27,901, ‘Cherry Choco Latte’ U.S. Plant Pat. No. 30,738 and ‘Turn of the Century’ (not patented).

‘Tie Dye’ has a taller, broader more open habit, the flower is flatter and the leaves are heterophyllous with many being tri-lobed and penta-lobed. ‘Starry Starry Night’ has a larger habit with darker greyed-purple, smaller, tri-lobed, the flower petals are less imbricate with a larger white portion and reddish pink veining. ‘Cherry Choco Latte’ has slightly shorter habit, more purplish-mahogany tinted foliage, and flowers with deep magenta veins on a near white background, petals with leading edges folded under. ‘Turn of the Century’ has a taller and more open habit; tri-lobed to penta-lobed lighter green foliage; and smaller, less rounded flowers; petals are less imbricate with thinner substance, and a center eye that is more orangish-red and less dark red, petal veins are closer together and pinkish colored, and the pollen is yellowish-grey.

The female parent plant is less compact in habit and the foliage was much darker greyed-purple. ‘Vintage Wine’ has a taller and more open habit with dark scarlet-red flowers and the foliage is broader.

Hibiscus ‘Spinderella’ is a unique hardy herbaceous Hibiscus with the following combined traits:

• • 1. Winter-hardy perennial with compact, dense, mounded habit of multiple, well-branched, basal stems;
  • 2. Many rotate flowers with a dark red eye, medium pink intensified distally and toward the leading petal edge and white near the eye and veins radiating toward the edges;
  • 3. Petals are overlapping and impressed at veins giving extra strength and resistance to wind damage;
  • 4. Flowers produced over a long period from late July to frost;
  • 5. Foliage is ovate and simple with a crenulate margin and deep-green with greyed-purple color in blotches.

The photographs of the new plant demonstrate the overall appearance of the plant, including the unique traits. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, source and direction may cause the appearance of minor variation in color. The plants in the photographs are from a four-year-old plant in an outdoor trial garden in Zeeland, Mich.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The new plant, Hibiscus ‘Spinderella’, has not been observed under all possible environments. The phenotype may vary slightly with different environmental conditions, such as temperature, light, fertility, moisture and maturity levels, but without any change in the genotype. The following observations and size descriptions are of four-year-old plants in the loamy-sand, open-field full-sun trials of a nursery in Zeeland, Mich. with supplemental fertilizer and water as needed. The plants are of natural habit and were not treated with plant growth regulators, nor were they pinched at any time in the growth year.
