plant named ‘JBG 19110’

Abstract

A new and distinct Hibiscus plant having bright pink with white colored flowers with a prominent eye and plentiful flowers.

Description

Botanical Classification: Hibiscus rosa-sinensis.

Varietal denomination: ‘JBG 19110’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct Hibiscus plant having the varietal name ‘JBG 19110’. The new variety is the result of a planned breeding program with the purposes of developing Hibiscus rosa-sinensis plants that exhibit whitefly and bacterial and fungal leaf spot resistance, propagation and production efficiencies, durable and exotic flowers, and abundant flowering. ‘JBG 19110’ is the result of a cross conducted in Grand Saline, Texas between Hibiscus rosa-sinensis varieties ‘AH-60’ (female parent, unpatented) and ‘MH-05’ (male parent, unpatented). The new variety was selected in April of 2018 in Grand Saline, Texas and the first asexual reproduction of the new variety was conducted by semi-hardwood cuttings in September of 2018 in Grand Saline, Texas. ‘JBG 19110’ has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations. The present invention has not been evaluated under all possible environmental conditions. However, it has been found to thrive in production and adapt well to the environment in Homestead, Florida. The phenotype may vary with variations in environment without a change in the genotype of the plant.

‘JBG 19110’ is similar to its female parent in having pink and white flower colors, petal ruffling, and foliage size and shape. However, its female parent has mostly white flowers with much less pink present, less visible flower streaking, and a light pink ring around the flower eye that is absent in ‘JBG 19110’. ‘JBG 19110’ is similar to its male parent in having a dark flower eye, upright and vigorous habit, exhibiting streaking in the flower veins, and in flower size. However, ‘JBG 19110’ differs from its male parent in overall flower color (its male parent is medium-orange in color), being more dense with increased foliage and self-branching, and exhibiting better foliage pest resistance.

When ‘JBG 19110’ is compared to Hibiscus rosa-sinensis variety having the commercial name “Runway Beauty” (unpatented), both varieties have a strong pink flower color, ruffled petals, and similar foliage shape. However, ‘JBG 19110’ has larger flowers, more vigorous growth, and improved pest and disease resistance.

The following traits distinguish ‘JBG 19110’ as a new and distinct cultivar from other Hibiscus varieties known to the breeder:

• • 1. Bright pink flower color with slightly overlapping blooms:
  • 2. Petal color changes from very dark pink in the winter to light pink with more white edging in the summer;
  • 3. Upright and outward growth habit; and
  • 4. Profuse flowering with multiple flowers open at once.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic images illustrate the new variety at approximately eleven months of age, with the colors being as nearly true as is possible with color illustrations of this type:

FIG. 1 illustrates a close-up view of a flower of the new variety; and

FIG. 2 illustrates an entire plant of the new variety.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new variety. The plants were grown in 2 gallon containers in a heated greenhouse with a minimum temperature of approximately 13° C. and about 30% light shade in the summer months. The color readings and measurements were taken indoors under fluorescent lights with natural light from a window nearby on approximately eleven month old plants. Color references are primarily to The 1995 R.H.S. Colour Chart of The Royal Horticultural Society of London, 3^rd Edition, except where general color terms are used.
