plant named ‘Plum Fantasy’

Abstract

A new and distinct cultivar of hardy herbaceous perennial Hibiscus hybrid plant named ‘Plum Fantasy’ comprising an upright dense branching, numerous flowers over a prolonged season having vibrant magenta-red overlapping petals and a darker red lustrous eye. The petals have a unique three-dimensional dimpling or puckering which helps resist strong wind, bright sun and harsh rain conditions. The foliage is dark-green, primarily heavily-dissected and tri-lobed.

Description

Botanical classification: Hibiscus hybrid (L.).

Variety denomination: ‘Plum Fantasy’.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to the new and distinct hardy, herbaceous, hibiscus plant, Hibiscus ‘Plum Fantasy’ hybridized by Clarence H. Falstad, III in the summer of 2007 at a nursery in Zeeland, Mich. The new plant, originally labeled # F7-16-01, is from a cross between Hibiscus ‘Summer Storm’ U.S. Plant Pat. No. 20,443 (female pod parent) times the proprietary hybrid # 05-139-17 (not patented) (male pollen parent). Both parents have a complex mixture of species in them, most likely including the species: moscheutos, coccineus and laevis (formerly militaris). Hibiscus ‘Plum Fantasy’ was first asexually propagated in 2010 by both stem 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 ‘Plum Fantasy’ differs from its parents as well as all other hardy herbaceous hibiscus known to the applicant in many traits. The foliage color of ‘Plum Fantasy’ is dark green with generally tri-lobed foliage. The most similar hibiscus in flower color known to the applicant is ‘Sultry Kiss’ U.S. Plant Pat. No. 22300, but the petals of the new plant are puckered three-dimensional in an unusual way and the color of ‘Plum Fantasy’ is a brighter color with slightly more magenta-red. Other hibiscus including: ‘Jazzberry Jam’ (not patented), ‘Tie Dye’ U.S. Plant Pat. No. 24,178 and ‘Berrylicious’ U.S. Plant Pat. No. 24,062 have rippled or pleated petals along the veins and margins but without the puckering of new plant which also give a greater three-dimensional appearance.

Hibiscus ‘Plum Fantasy’ is a unique hardy herbaceous hibiscus with the following combined traits:

• • 1. Hardy perennial with dense branching.
  • 2. Many flowers over a prolonged season having vibrant magenta-red overlapping petals and a darker red lustrous eye.
  • 3. Petals have a unique dimpling or puckering giving the appearance of a three-dimensional petals and helping resist strong wind, bright sun and rain conditions.
  • 4. Dark-green, heavily-dissected primarily tri-lobed foliage.

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 ‘Plum Fantasy’, 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.
