USPP13734P2 - Hibiscus plant named ‘Angelique’ - Google Patents

Abstract

A new and distinct cultivar of winter hardy hibiscus plant named ‘Angelique’ 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, tubular white flowers with red centers and recurved petal edges and its shiny “Maple-like” green leaves and unusual pyramidal compactness of about 3 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.

Description

BOTANICAL CLASSIFICATION

Hibiscus moscheutos×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) Refined and noticeably shiny, “Maple-like”, green leaves which have smooth margins and white buds s which combined compliments the landscape;

(b) Medium-sized flowers that are outstanding for their bright white overlapping petals with red eyezones that have a tubular shape and recurved petal edges;

(c) The plant being very floriferous with flowers that stay open at least one full day, sometimes two;

(d) The plant being small but vigorous with stouter stems, compact and “pyramidal” breaking action which gives it unique landscape utility; and

(e) The plant being so hardy that it can consistently withstand winter temperatures of a least −30 degrees Fahrenheit.

(f) The plant being a genetic achievement as a hybrid between a tropical and hardy Hibiscus.

SUMMARY OF THE INVENTION

‘Angelique’ 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 ‘Bright Eye’, a 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 unique and distinguishing 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 charateristics. This TROPICAL—HARDY™ Hibiscus plant greatly contributes to the market with its tropical aspect, sheer beauty and utter refinement, its compact growth habit, its enhanced resistance to disase 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 photograph. More specifically, the photograph is a close-up of the flower and the leaf.

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.

‘Angelique’ has not been observed under all possible environmental 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, however any 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).
