ABSTRACT:
BACKGROUND OF THE INVENTION
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 Caroline.
The new Hibiscus 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 freely-branching Hibiscus cultivars with uniform and compact plant habit 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 Hibiscus originated from a cross made by the Inventor in Alva, Fla., of a proprietary
Hibiscus rosa
-
sinensis
selection, designated as code number YB-0602, as the female, or seed, parent with a proprietary
Hibiscus rosa
-
sinensis
selection, designated as code number YB-1340, as the male, or pollen, parent. The cultivar Caroline 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 Sep. 13, 1995.
Compared to plants of the female parent, the proprietary Hibiscus selection code number YB-0602, plants of the new Hibiscus are more compact; have slightly glossier leaves; and have lighter and brighter flower color. In addition, flowers of plants of the new Hibiscus do not have the contrasting “eye” color, however flowers of plants of the female parent have strong pink-colored “eyes”. Plants of new Hibiscus have slightly lighter green and less glossy foliage; produce more flowers per day per plant; have smaller flowers; flower about one week later; and differ in flower color when compared to plants of the male parent, the proprietary Hibiscus selection code number YB-1340.
Asexual reproduction of the new Hibiscus 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.
SUMMARY OF THE INVENTION
The cultivar Caroline 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 ‘Caroline’. These characteristics in combination distinguish ‘Caroline’ as a new and distinct cultivar:
1. Glossy, undulate, very dark green leaves.
2. Upright, outwardly spreading, uniform, dense and symmetrical plant habit that is appropriate for container production.
3. Very freely flowering, numerous orance-colored flowers.
4. Good resistance to flower bud abscission.
5. Excellent postproduction longevity.
Plants of the new Hibiscus can be compared to plants of the cultivar Mango Breeze, disclosed in U.S. Plant Pat. No. 11,027. However, in side-by-side comparisons conducted in Alva, Fla., plants of the new Hibiscus differ from plants of the cultivar Mango Breeze in the following characteristics:
1. Plants of the new Hibiscus are slightly more vigorous than plants of the cultivar Mango Breeze.
2. Flower color of plants of the new Hibiscus is brighter and more intense orange compared to flower color of plants of the cultivar Mango Breeze.
3. Flower margins of plants of the new Hibiscus are not as heavily ruffled as flower margins of plants of the cultivar Mango Breeze.
Plants of the new Hibiscus can also be compared to plants of the cultivar Desert Wind, disclosed in U.S. Plant Pat. No. 10,941. However, in side-by-side comparisons conducted in Alva, Fla., plants of the new Hibiscus differ from plants of the cultivar Desert Wind in the following characteristics:
1. Plants of the new Hibiscus are not as outwardly spreading as plants of the cultivar Desert Wind.
2. Plants of the new Hibiscus have slightly lighter green foliage than plants of the cultivar Desert Wind.
3. Plants of the new Hibiscus have smaller flowers than plants of the cultivar Desert Wind.
4. Flower color of plants of the new Hibiscus is much brighter and more intense orange than flower color of plants of the cultivar Desert Wind.
5. Plants of the new Hibiscus flower about one week earlier than plants of the cultivar Desert Wind.
