Abstract

A new and distinct cultivar of hardy herbaceous perennial Hibiscus hybrid plant named ‘Starry Starry Night’ comprising dense branching habit with dark greyed-purple, tri-foliate leaves over a large portion of the mound. The flowers are flat, upward and outward facing, with pinwheel-varying light-pink and magenta colored face, veins and speckles, and have a darker red eye.

Description

Botanical classification: Hibiscus hybrid (L.).

Variety denomination: ‘Starry Starry Night’.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to the new and distinct hardy, herbaceous, hibiscus plant, Hibiscus ‘Starry Starry Night’ hybridized by the inventor on Jul. 27, 2011 at a nursery in Zeeland, Mich. The new plant, originally labeled # 11-117-104, is a single seedling selection from a cross between Hibiscus ‘Crown Jewels’ U.S. Plant Pat. No. 11,857 (female pod parent) times Hibiscus ‘Midnight Marvel’ U.S. Plant Pat. No. 24,079 (male pollen parent). The seed was harvested on Nov. 11, 2011 the specific seedling passed the initial trial in the summer of 2012. Both parents have a complex mixture of species in them, most likely including the species: moscheutos and coccineus. Hibiscus ‘Starry Starry Night’ was first asexually propagated in 2013 by both stem tip cuttings and sterile tissue culture 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 ‘Starry Starry Night’ differs from its parents as well as all other hardy herbaceous hibiscus known to the applicant in many traits. The foliage color of ‘Starry Starry Night’ is very dark greyed-purple with generally tri-lobed foliage and occasional 5-lobed. The most similar hibiscus in flower color known to the applicant is ‘Small Wonders’ U.S. Plant Pat. No. 24,022, but the flower face of the new plant is flatter and not as cupped as ‘Small Wonders’ and the habit of the new plant is much larger mound. Other similar hibiscus include: ‘Kopper King’ U.S. Plant Pat. No. 10,793, ‘Summer Storm’ U.S. Plant Pat. No. 20,443, ‘Cherry Cheesecake’ U.S. Plant Pat. No. 26,089 and ‘Turn of the Century’ (not patented). ‘Kopper King’ has larger flowers, flowers for a shorter period, the petals have less veining, the foliage is not as dark, and the habit is larger and more open. ‘Summer Storm’ flowers for a longer period, the petals have less veining, and the habit is taller. ‘Cherry Cheesecake’ has petals with more folding along veins and more magenta tinting at petal apex rather than on the side of the petal. ‘Turn of the Century’ has more finely-dissected green foliage, smaller flowers with less veining and a more columnar plant habit with less branching. ‘Starry Starry Night’ has more foliage showing the darker greyed-purple coloration than all of the above cultivars and any cultivar known to the inventor.

Hibiscus ‘Starry Starry Night’ is a unique hardy herbaceous hibiscus with the following combined traits:

• • 1. Hardy perennial producing herbaceous mound with dense branching;
  • 2. Primarily tri-lobed foliage with very dark greyed-purple color over a large portion of the mound.
  • 3. Many flowers up to 22 cm across over a prolonged season having a pinwheel-color effect of lighter pink on the exposed petal edge and becoming darker clock-wise toward the overlapped petal edge, accented by deep pink veining and a darker red lustrous eye.
  • 4. Petals open to a flat face and recurve slightly toward apex.
  • 5. Pink petal coloration toward apex in fine air-brushing-like spots.
  • 6. Flowers self-cleaning leaving behind bright green calyx sharply contrasting with very dark foliage effect.

BRIEF DESCRIPTION OF THE DRAWINGS

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.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The new plant, Hibiscus ‘Starry Starry Night’, 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 three 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 natural habit and were not treated with plant growth regulators, nor were they pinched at any time in the growth year.
