Hibiscus plant named ‘Carafe Yochablis’

Abstract

A new and distinct Hibiscus plant named ‘Carafe Yochablis’, characterized by its upright and somewhat outwardly spreading plant habit; freely branching and vigorous growth habit; early flowering habit; large white single flowers blushed with pink towards the center and occasionally towards the margins; and excellent garden performance.

Description

Botanical designation: Hibiscus moscheutos.

Cultivar denomination: ‘Carafe Yochablis’.

CROSS-REFERENCE TO RELATED APPLICATIONS

Hibiscus Plant named ‘Carafe Yobordeaux’; Mark A. Smith, applicant; disclosed in a U.S. Plant patent application filed concurrently.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hibiscus moscheutos, and hereinafter referred to by the name ‘Carafe Yochablis’.

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 and Hibiscus cultivars with a compact plant habit and attractive flower coloration.

The new Hibiscus originated from a self-pollination made by the Inventor in Alva, Fla. during the summer of 2001 of the Hibiscus moscheutos cultivar Carafe Yobordeaux, disclosed in a U.S. Plant patent application Ser. No. 11/178,272. The cultivar Carafe Yochablis was discovered and selected by the Inventor as a flowering plant within the progeny of the stated self-pollination in a controlled environment in Alva, Fla. in April, 2002.

Asexual reproduction of the new Hibiscus by vegetative terminal cuttings in a controlled environment in Alva, Fla. since May, 2002, 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 Carafe Yochablis has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Carafe Yochablis’. These characteristics in combination distinguish ‘Carafe Yochablis’ as a new and distinct cultivar:

• • 1. Upright and somewhat outwardly spreading plant habit.
  • 2. Freely branching and vigorous growth habit.
  • 3. Early flowering habit.
  • 4. Large white single flowers blushed with pink towards the center and occasionally towards the margins.
  • 5. Excellent garden performance.

Plants of the new Hibiscus can be compared to plants of the parent, the cultivar Carafe Yobordeaux. Plants of the new Hibiscus differ from plants of the cultivar Carafe Yobordeaux in the following characteristics:

• • 1. Plants of the new Hibiscus flower about two days later than plants of the cultivar Carafe Yobordeaux.
  • 2. Plants of the new Hibiscus and the cultivar Carafe Yobordeaux differ in flower coloration as plants of the cultivar Carafe Yobordeaux have red-colored flowers.

Plants of the new Hibiscus can be compared to plants of the Hibiscus cultivar Blue River II, not patented. In side-by-side comparisons conducted in Alva, Fla., plants of the new Hibiscus differed from plants of the cultivar Blue River II in the following characteristics:

• • 1. Plants of the new Hibiscus were shorter, fuller and stronger than plants of the cultivar Blue River II.
  • 2. Plants of the new Hibiscus and the cultivar Blue River II differed in flower color as plants of the cultivar Blue River II had pure white-colored flowers.

Plants of the new Hibiscus can also be compared to plants of the Hibiscus cultivar Disco Belle White, not patented. In side-by-side comparisons conducted in Alva, Fla., plants of the new Hibiscus differed from plants of the cultivar Disco Belle White in the following characteristics:

• • 1. Plants of the new Hibiscus were taller and fuller than plants of the cultivar Disco Belle White.
  • 2. Plants of the new Hibiscus flowered about three days later than plants of the cultivar Disco Belle White.
  • 3. Plants of the new Hibiscus had larger flowers than plants of the cultivar Disco Belle White.
  • 4. Plants of the new Hibiscus and the cultivar Disco Belle White differed in flower color as plants of the cultivar Disco Belle White had white-colored flowers with distinct red purple-colored centers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Hibiscus, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Hibiscus.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Carafe Yochablis’ grown in an outdoor nursery in Alva, Fla. for about six months.

The photograph on the second sheet comprises a close-up view of a typical flower of ‘Carafe Yochablis’.

DETAILED BOTANICAL DESCRIPTION

The following observations, measurements and values describe plants grown in Alva, Fla. in one-gallon containers in a polypropylene-covered shadehouse during the summer and under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 29° C. to 32° C. and night temperatures ranged from 21° C. to 24° C. Plants were pinched about one month after planting. The description was taken about two months after the pinch. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
