Hibiscus plant named ‘Hoosiers’

Abstract

A new and distinct cultivar of Hibiscus plant named ‘Hoosiers’, characterized by its upright and somewhat spreading plant habit; vigorous growth habit; shiny dark green leaves; large and unique bi-colored flowers with pure white center surrounded by dark red margin; and red and white vertically striped styles.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus, botanically know as Hibiscus rosa-sinensis and hereinafter referred to by the cultivar name ‘Hoosiers’.

The new Hibiscus is a product of a planned breeding program conducted by the Inventor in Fort Myers, Fla. The objective of the program was to create new Hibiscus selections with red and white bi-colored flowers.

The new Hibiscus originated from a cross made by the Inventor in Fort Myers, Fla., of the Hibiscus rosa-sinensis cultivar ‘Starfish’, not patented, as the female, or seed, parent with the Hibiscus rosa-sinensis cultivar ‘Coconut Ice’, not patented, as the male, or pollen, parent. The cultivar ‘Hoosiers’ was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Fort Myers, Fla.

Plants of the new Hibiscus have white and dark red bi-colored flowers, whereas plants of the cultivar ‘Starfish’ have yellow and red-orange bi-colored flowers and plants of the cultivar ‘Coconut Ice’ have light pink-colored flowers.

Asexual reproduction of the new Hibiscus by terminal cuttings taken in a controlled environment in Fort Myers, 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 ‘Hoosiers’ has not been observed under all possible environmental conditions. The phenotype may vary somwehat 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 ‘Hoosiers’. These characteristics in combination distinguish ‘Hoosiers’ as a new and distinct cultivar:

1. Upright and somewhat spreading plant habit.

2. Vigorous growth habit.

3. Shiny dark green leaves.

4. Large and unqiue bi-colored flowers with pure white center surrounded by dark red margin.

5. Style base with red and white vertical stripes.

Plants of the new Hibiscus can be compared to plants of the cultivar ‘Restless Heart’, not patented. However, in sidy-by-side comparisons conducted in Fort Myers, Fla., plants of the new Hibiscus differ from plants of the cultivar ‘Restless Heart’ in the following characteristics:

1. Flowers of plants of the new Hibiscus have a larger white central area and darker red margin color than flowers of plants of the cultivar ‘Restless Heart’.

2. Plants of the new Hibiscus have red and white striped styles whereas plants of the cultivar ‘Restless Heart’ have white styles.

Plants of the new Hibiscus can be compared to plants of the cultivar ‘Red 'N White’, not patented. However, in side-by-side comparisons conducted in Fort Myers, Fla., plants of the new Hibiscus differ from plants of the cultivar ‘Red 'N White’ in the following characteristics:

1. Flowers of plants of the new Hibiscus have a larger white central area and darker red margin color than flowers of plants of the cultivar ‘Red 'N White’.

2. Plants of the new Hibiscus have red and white striped styles whereas plants of the cultivar ‘Red 'N White’ have white styles.

3. Flowers of plants of the new Hibiscus have distinct red and white areas whereas flowers of plants of the cultivar ‘Red 'N White’ have white spots scattered throughout the red area.

The photograph at the bottom of the sheet comprises a close-up view of a typical flower of ‘Hoosiers’.

DETAILED BOTANICAL DESCRIPTION

The following observations, measurements and values describe plants grown in Fort Myers, Fla., during the late spring, under polypropylene shadecloth providing a 40 percent light reduction, and conditions which closely approximate commercial production. Plants described were about one-year old.

In the description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
