| Abstract: |
A new and distinct cultivar of winter hardy hibiscus plant named `Pink Comet` is the result of a unique hybridization. This new and distinct cultivar is characterized primarily as to novelty by its tropical aspects, its extreme cold hardiness to Zone 4, its medium-sized, thick-textured, pink flowers with pale pink to white reverse having multiple markings of red and pink on both sides of the petals and its shiny green leaves and unusual compactness of about 2 feet, its vigorous and uniform growth habit, and its floriferous nature from midsummer until frost, and its genetic achievement as a cross between a tropical and hardy Hibiscus. |

It is claimed:
1. A new and distinct cultivar of Hibiscus plant, as herein shown and described. |
| Description: |
BOTANICAL CLASSIFICATION
Hibiscus moscheutos.times.H. rosa-sinensis.
BACKGROUND OF THE NEW PLANT
The new plant of this invention is the result of a unique hybridization, with the breeding achievement being evidenced in the outstanding combination of characteristics exhibited by this new and distinct Hibiscus plant, which include: (a) Refinedand noticeably shiny, "Maple-like", green leaves which have relatively smooth margins and white buds with red and pink markings which combined compliments the landscape; (b) Medium-sized flowers that are outstanding for their pink petals with pale pinkto white reverse having red and pink markings on both sides of the petals; (c) The plant being very floriferous with flowers that stay open at least one full day; (d) The plant being small but vigorous with stouter stems compact and uniform breakingaction which gives it unique landscape utility; and (e) The plant being so hardy that it can consistently withstand winter temperatures of at least -30 degrees Fahrenheit. (f) The plant being a gentic achievement as a hybrid between a tropical and hardyHibiscus.
SUMMARY OF THE INVENTION
`Pink Comet` was the result of a 40-year breeding program. Its ancestry includes Hibiscus moscheutos and Hibiscus rosa-sinensis. More specifically, the plant resulted from multiple crossings with an unnamed Fleming Hibiscus rosa-sinensis(nonpatented) and a unnamed Fleming Hibiscus moscheutos (nonpatented). The seedling which most nearly met all of the above named standards was selected.
This new plant first bloomed in the summer of 1989 and was selected by David Fleming and Gretchen Zwetzig on David Fleming's property in Lincoln, Nebr. Asexual propagation of the plant by cuttings and root division has shown that the unique anddistinguishing features of the plant are faithfully transmitted from generation to generation and appear to be fixed.
Since its origin, the plant has bloomed from midsummer until frost, while exhibiting the aforementioned distinctive characteristics. This TROPICAL-HARDY.TM. Hibiscus plant greatly contributes to the market with its tropical aspect, sheer beautyand utter refinement, its compact growth habit, its enhanced resistance to disease and insects, its stability through extremes in rain and drought, and its extreme hardiness.
BRIEF DESCRIPTION OF THE DRAWINGS
The flower and foliage of the cultivar are shown in the attached photographs
More specifically, the first photograph is a close-up of the flower and the leaf. The second photograph is the reverse of the petals, close-up.
The colors are as true as is reasonably possible to attain in photographic illustrations of this type. The colors illustrated may be slightly off due to light reflectance.
DESCRIPTION OF THE NEW PLANT
What follows is a detailed description of the new cultivar. The specific color descriptions are in accordance with the Dictionary of Color (Maerz and Paul), while general color recitations are consistent with ordinary American color terminology.
`Pink Comet` has not been observed under all possible environment conditions. It is to be understood that the phenotype may vary significantly with variations in environment such as temperature, light intensity, and day length, without, howeverany difference in genotype of the plant. The following botanical characteristics and observations are gathered from the plant when grown in Lincoln, Nebr. (USDA Zone 4).
THE PLANT Parentage: Seed parent.--Hibiscus moscheutos, Unnamed and unpatented Fleming seedling. Pollen parent.--Hibiscus rosa-sinensis Unnamed and unpatented Fleming seedling. Origin: A selected seedling from stated cross. Type of plant:Hardy, herbaceous perennial with some tropical genetics. Classification: Variety of TROPICAL-HARDY.TM. Hibiscus plant. Propagation: Relatively easy to propagate; holds its distinguishing characteristics through successive cuttings and division. Size:About 21/2 feet tall and about 2 ft. wide. Form: Symmetrical annual growth from perennial roots. Habit: Upright and uniformly branched. Growth: Vigorous; small and very compact. Full grown (2 ft.) in 2 years. Hardiness: Hardy to at least -30degrees Fahrenheit. General health: Plant is very disease resistant against rot, aphids, spider mites, scale, white fly, etc.; sturdy through excessive drought, rain, or wind. Propagation: Relatively easy and fast rooting in approximately 2 weeks. Foliage: 1. Arrangement.--Alternate. 2. Shape.--Juvenile: Variable, ovate to 3-lobed leaf. Rounded base shape.

THE FLOWER Blooming period: Profuse from July until frost. Flower diameter: Medium to large; about 71/2 inches (17 cm). Borne: Singly in leaf axils, from midpoint of stems upward. Bloom duration: Individual bloom lasts at least one full day,sometimes 2. Form: Campanulate; petals are also very overlapping. Bud: 1. Length.--About 21/4 inches (or 6 cm) on day before opening. 2. Color.--1-D, PLATE 3, page 29. 3. Surface texture.--Semi-glabrous. 4. Duration.--One to two weeks. Corolla:Having 5 petals. 1. Petal character and dimensions.--Campanulate and very overlapping.

GENERAL OBSERVATIONS
This plant, as a hybridized TROPICAL-HARDY.TM. Hibiscus, is valuable to the landscape market for its improvements in tropical aspect, thicker-textured and uniquely marked flowers and buds, shiny and refined, "Maple-like" green foliage on a muchmore compact plant, its all-around vigor, good breaking action, and adaptation to extreme environments, including the ability to consistently survive winter temperatures of at least -30 degrees Fahrenheit.
