Description

The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hibiscus rosa-sinensis, and hereinafter referred to by the cultivar name Sahara Wind.

The new cultivar is a product of a planned breeding program conducted by the inventor in Alva, Fla. The objective of the breeding program is to create new Hibiscus cultivars having uniform and compact plant habits appropriate for container production, early and uniform flowering, numerous flowers per lateral branch, desirable flower color, resistance to flower bud abscission, and good postproduction longevity.

The new cultivar originated from a cross made by the inventor in Alva, Fla., of a proprietary Hibiscus rosa-sinensis selection, designated as code number 511, as the female, or seed, parent with the Hibiscus rosa-sinensis cultivar Waikiki (disclosed in U.S. Plant Pat. No. 7,834) as the male, or pollen, parent. The cultivar Sahara Wind was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Alva, Fla., on Jul. 13, 1994.

Compared to plants of the female parent, the proprietary Hibiscus selection code number 511, plants of the new Hibiscus have lighter green and larger leaves, more outwardly spreading plant habit, and larger flowers. Plants of the new Hibiscus differ in flower color, have a more outwardly spreading plant habit, and flower about one week earlier than plants of the male parent, the cultivar Waikiki.

Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Alva, Fla., has shown that the unique features of this new Hibiscus are stable and reproduced true to type in successive generations.

The cultivar Sahara Wind has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, nutrition and water status without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Sahara Wind`. These characteristics in combination distinguish `Sahara Wind` as a new and distinct cultivar:

1. Large dark green leaves.

2. Upright and outwardly spreading, uniform and symmetrical plant habit that is appropriate for container production.

3. Very freely flowering, numerous large light orange-colored flowers with red throats.

4. Good resistance to flower bud abscission.

5. Excellent postproduction longevity.

Plants of the new Hibiscus can be compared to plants of the nonpatented cultivar Sundance. However, in side-by-side comparisons conducted in Alva, Fla., plants of the new cultivar differ from plants of the cultivar Sundance in the following characteristics:

1. Plants of the new Hibiscus are more compact than plants of the cultivar Sundance.

2. Plants of the new Hibiscus are more freely branching than plants of the cultivar Sundance.

3. Plants of the new Hibiscus flower about one week earlier than plants of the cultivar Sundance.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored freproductions of this type.

The photograph at the top of the sheet comprises a top perspective view of typical plant of `Sahara Wind`.

The photograph at the bottom of the sheet comprises a close-up view of a typical flower of `Sahara Wind`. Flower and foliage colors in the photographs may appear different from the actual colors due to light reflectance.

DETAILED BOTANICAL DESCRIPTION

C. and night temperatures ranging from 10 to 24.degree. C. In the description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
