| Abstract: |
A novel Hibiscus paeoniflorus L. plant characterized by the combination of its variegated leaves; showy candy-striped bloom buds; semi-double flower form; excellent pot habit; good flower production; ease of rooting cuttings; flower life of two days; medium-sized leaves, mostly three lobed with rounded teeth or notches; and durability as a landscape subject. |
| Claim: |
I claim:
1. A new and distinct variety of Hibiscus paeoniflorus L., substantially as herein shown and described, and characterized particularly as to novelty by the combination of its variegatedleaves; showy candy-striped bloom buds; and semi-double flower form. |
| Description: |
This invention relates to a new and distinct variety of hibiscus of the species botanically known as Hibiscus paeoniflorusL. I have selected "Hillis Variegated" as the varietal name for my new variety.
I originally noticed my new variety growing as one distinctive flowering branch on the parent cultivar growing in a cultivated area and more specifically in a nursery row at Hillis Nursery Company, Inc., Warren County, Tenn. This branch wasparticularly characterized and distinctive from the parent plant by its medium-sized variegated leaves which were variably shaped and three-lobed with notches, showy candy-striped blooms, semi-double flower form, good flower production, and a flower lifeof two days. The plant also demonstrated an ease of propagation by root cuttings, excellent pot habit, and durability in direct sunlight. The parent cultivar is Althea paeoniflorus L. I believed that the branch of my new variety that I first noticed onthe parent plant was a limb sport of the parent plant.
Observation of these distinct features of the limb sport convinced me that it represented a new and distinct variety of hibiscus. The new cultivar was first asexually reproduced by taking softwood vegetative cuttings from the originally observedbranch of the parent cultivar. Observation of this limb sport and continued observation and testing of progeny thereof, subsequently asexually propagated under my direction at Hillis Nursery Company by vegetative cuttings, has confirmed my observationthat the selection comprises a new and distinct variety of hibiscus. In addition, horticultural examinations of successive generations of asexually propagated plants has repeatedly shown that the unique combination of characteristics displayed by my newvariety are fixed and retained through successive generations of asexual reproduction.
Accordingly, I am convinced that my new plant represents a new and improved variety of Hibiscus paeoniflorus L., as evidenced by the following unique combination of characteristics which have proven firmly fixed and which distinguish it from allother varieties of this species:
(1) Variegated leaves;
(2) Showy candy-striped bloom buds; and
(3) Semi-double flower.
The accompanying photographs depict the color and foliage of my new variety as nearly true as is reasonably possible in a color illustration of this character.
FIG. 1 is a color photograph of the present invention grown as a finished pot plant.
FIG. 2. is a color photograph illustrating the distinctive characteristics of the flower and variegated leaves of the present invention, compared with the flower and leaves of the parent cultivar.
FIG. 3 is a color photograph showing the variation in leaf shape that can be found on any single plant, and typical patterns of variegation.
FIG. 4 is a color photograph showing the colorful, candy-striped bloom bud of the present invention.
FIG. 5 is a color photograph showing bloom buds and a flower of the present invention.
One of the primary distinguishing characteristics of my new variety of hibiscus over other hibiscus varieties in the variegation of the leaves and thecharacteristically variable leaf shape. FIG. 2 best illustrates the variegation typical of my new variety. The variegated plant shown on the left of the photograph is the plant of the present invention, whereas the non-variegated plant on the right isthe parent cultivar.
The characteristically variable leaf shape displayed by the present invention is best shown in FIG. 3. It may be noted that there is variability in the shape of the leaves of the new selection within any single plant.
The parent cultivar, Althea paeoniflorus L., is believed by the inventor to be the most similar cultivar. The variegated leaves of the present invention particularly characterize "Hillis Variegated" from the parent cultivar (FIG. 2); in allother respects the two plants are similar insofar as has been observed as of this time.
The following is a detailed description of my new variety of Hibiscus paeoniflorus L., with color terminology in accordance with The Royal Horticultural Society Colour Chart (hereinafter R.H.S.), published by The Royal Horticultural Society ofLondon, England. The phenotype of the present invention may vary with changes in environmental conditions and factors such as light intensity and temperature; the plant has not been observed under all possible environmental conditions. The followingphenotypic description is of a plant of the present invention grown in an outdoor container at Hillis Nursery Company, Inc., Warren County, Tenn.
