plant named ‘Perfect Storm’

Abstract

A new and distinct cultivar of winter-hardy, herbaceous, perennial, hybrid Hibiscus plant named ‘Perfect Storm’ comprising a short compact habit of multiple, well-branched, basal stems producing numerous flowers from the ground up, over a prolonged season having light pink to near white base and bright-red eye and veins and marginal red tinting. The foliage is three to five-lobed, deeply dissected, maple-like and dark purple colored.

Description

Botanical classification: Hibiscus hybrid (L.).

Variety denomination: ‘Perfect Storm’.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to the new and distinct hardy, herbaceous, hibiscus plant, Hibiscus ‘Perfect Storm’ hybridized by the inventor on Jul. 27, 2011 at a nursery in Zeeland, Mich. The new plant is a single seedling selection from a cross between Hibiscus ‘Crown Jewels’ U.S. Plant Pat. No. 11,857 (female seed parent) times Hibiscus ‘Midnight Marvel’ U.S. Plant Pat. No. 24,079 (male pollen parent). The seeds were harvested on Nov. 11, 2011 and the specific seedling passed the initial trial in the summer of 2013 at which time it was assigned the breeder code labeled # 11-117-6. Both parents have a complex mixture of species in them, most likely including the species: moscheutos and coccineus. Hibiscus ‘Perfect Storm’ was first asexually propagated in 2013 by sterile shoot-tip 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.

No plants have been sold, either in this country or anywhere in the world, prior to the filing of this application, nor has any disclosure been made prior to the filing of this application with the exception of that which was within one year of the filing of this application and was derived directly or indirectly from the inventor.

BRIEF SUMMARY OF THE PLANT

Hibiscus ‘Perfect Storm’ differs from its parents as well as all other hardy herbaceous hibiscus known to the applicant in many traits. The most similar hibiscus in flower color known to the applicant are Hibiscus ‘Summer Storm’ U.S. Plant Pat. No. 20,443, Hibiscus ‘Kopper King’ U.S. Plant Pat. No. 10,793 and Hibiscus ‘Copper Queen’ U.S. Plant Pat. No. 23,941. The habit of the new plant is shorter and more compact. Compared to the female parent ‘Crown Jewels’ the new plant has much darker purple foliage, the flowers are larger and have more red veining. Compared to the male parent ‘Midnight Marvel’, the new plant has flowers that are more white with red veining, and the habit is shorter and more compact. Compared to ‘Summer Storm’, the new plant is shorter and more compact. Compared to ‘Kopper King’, the new plant is darker purple and finer in leaf texture; shorter, more compact and more branched in habit; and flowers for a longer season with flowers that cover from the bottom to the top of the plant. Compared to ‘Copper Queen’, the new plant has darker purple foliage and the flowers are flatter faced.

Hibiscus ‘Perfect Storm’ is a unique hardy herbaceous hibiscus with the following combined traits:

• • 1. Winter-hardy, perennial with short compact habit of multiple, well-branched, basal stems.
  • 2. Many rotate, flat-faced flowers over a prolonged season being produced from the ground to the top of the plant.
  • 3. Flower petals having very light pink to near white base, a lustrous bright-red eye zone and veins of bright-red, with marginal red tinting on the distal portion.
  • 4. Dark-purple, deeply-dissected, three to five-lobed, maple-like foliage.

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 ‘Perfect Storm’, 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 of natural habit and were not treated with plant growth regulators, nor were they pinched at any time in the growth year.
