Hibiscus plant named `Inner Glow`
Abstract
A new and distinct cultivar of winter-hardy, herbaceous,
perennial, hybrid Hibiscus plant named `Inner Glow` comprising an
upright, dense, mound habit of multiple, well-branched,
mostly-upright basal stems producing flowers in the upper one-third
to one-half of the plant for at least six weeks beginning late July
to early August. Flowers have petals that are slightly cupped and
slightly puckered and folded, of rich rose-pink with shiny
moderate-red eye, a pale lavender-purple hallow center and a deep
red and white striped column displaying yellow-colored pollen. The
foliage is mainly tri-lobed with olive green and moderate burgundy
color blushing. The new plant is useful in the landscape as a
specimen plant or en masse.

Claims
I claim:
1. A new cultivar of hardy herbaceous perennial Hibiscus plant
named `Inner Glow` as herein illustrated and described.
Description
Botanical classification: Hibiscus hybrid (L.).
Variety denomination: `Inner Glow`.
STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(B)(6)
The first publically released non-enabling description was a
photograph and brief description of the new plant first on Feb. 1,
2021 when it was listed on a website operated by Walters Gardens,
Inc. Subsequently, the new plant had a non-enabling description and
photograph in the "Walters Gardens 2021-2022 Catalog" first
released on May 21, 2021. The first disclosure, in the form of a
sale, was made by Walters Gardens, Inc. on Mar. 29, 2021 to
Bachman's Wholesale Nursery followed by sales to Legacy Gardens.
Walters Gardens, Inc. obtained the new plant and all information
relating thereto, from the inventor. No plants of Hibiscus `Inner
Glow` have been sold, in this country or anywhere in the world, 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 and would be 35 U.S.C .sctn. 102(b)
exceptions.
BACKGROUND AND ORIGIN OF THE PLANT
The present invention relates to the new and distinct hardy,
herbaceous, Hibiscus plant, Hibiscus `Inner Glow` hybridized under
direction of the inventor on Aug. 30, 2016 at a wholesale perennial
nursery in Zeeland, Mich. The new plant is a self-pollination of
`Evening Rose` U.S. Plant Pat. No. 33,366. Into the trial process
the new plant was assigned the breeder code labeled 16-33-1. The
parent has a complex mixture of species, comprising the species:
moscheutos and coccineus.
Hibiscus `Inner Glow` was first asexually propagated in late summer
of 2018 by sterile shoot-tip tissue culture and later by greenhouse
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 `Inner Glow` differs from its parents as well as all other
hardy herbaceous Hibiscus known to the applicant in many traits.
The most similar Hibiscus known to the applicant are `Tie Dye` U.S.
Plant Pat. No. 24,078, `Airbrush Effect` U.S. Plant Pat. No.
29,295, and `Spinderella` U.S. Plant Pat. No. 33,309.
`Tie Dye` is taller and more upright in habit, the foliage lacks
the burgundy coloration, and the inner flower portion surrounding
the eye is nearly white. `Airbrush Effect` has foliage that is dark
green, and the flowers are vibrant pink with salmon tones that
appear speckled in greater concentration toward the apex.
`Spinderella` has a taller and broader habit, the foliage is ovate
and deep-green colored, and the flowers have a darker pink leading
edge and the apex of the petals with the overlapped edge of nearly
white.
`Evening Rose` has flowers of vivid purplish-red coloration,
without the lighter portion surrounding the eye.
Hibiscus `Inner Glow` is a unique winter-hardy herbaceous Hibiscus
with the following combined traits: 1. Winter-hardy compact
perennial with upright habit of multiple, well-branched, basal
stems; 2. Many flat rotate flowers; 3. Flowers produced for about
five to six weeks beginning mid-summer; 4. Flower petals of rich
rose-pink with deep red and white striped column displaying yellow
pollen; 5. Flower is slightly cupped with slight puckering and
folding in petals giving extra strength and support to flower; 6.
Flower has a moderate-red shiny eye zone surrounded by pale
lavender-purple halo center; 7. Foliage is mainly tri-lobed, olive
green with moderate burgundy blushing.
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.
FIG. 1 shows a close-up of the flower and bud.
FIG. 2 shows a four-year-old plant in full flower in a trial
garden.
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
`Inner Glow`, 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. Parentage: The parent is `Evening Rose`;
