plant named ‘Panama Bronze’

Abstract

Hibiscus ‘Panama Bronze’ is an ornamental variety, crossed and cultivated in Georgia. The plants of the new Hibiscus variety display new growth with an intense bronze color in high light that matures to a green color with bronze edging, deeply cut foliage, stable foliage color, very large flowers, thrives in hot an humid conditions, and flowers heavily during short days (November to April) in zone 10. ‘Panama Bronze’ can be grown in the garden or in a container.

Description

Latin name: Hibiscus ‘Panama Bronze’ is of the genus and species Hibiscus acetosella×Hibiscus radiatus.

Varitey denomination: The new Hibiscus claimed is of the variety denominated ‘Panama Bronze.’

CROSS-REFERENCE TO RELATED APPLICATIONS

This patent application is related to U.S. application Ser. No. 11/881,889, invented by the same Inventor, assigned to the same Assignee, and filed simultaneously with, the present application. Cross-reference application Hibiscus ‘Panama Red’ is the material parent plant of the present Hibiscus ‘Panama Bronze.’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hibiscus acetosella×Hibiscus radiatus, and herein referred to as ‘Panama Bronze.’

The new Hibiscus is a product of a planned breeding program conducted by the Inventor in Tifton, Ga. The objective of the Hibiscus breeding program is to create new plant cultivars with ornamental leaf distinctions and abundant flowers.

The new Hibiscus originated from a cross-pollination made by the Inventor during 2005, of the Hibiscus acetosella ‘Panama Red’ (co-pending U.S. patent application Ser. No. 11/881,889) as the female and Hibiscus radiatus (not patented) as the male, or pollen parent. The cultivar ‘Panama Bronze’ was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in 2006.

Asexual reproduction of the new Hibiscus by vegetative terminal cutting in a controlled environment in Tifton, Ga. since 2006, has shown that the unique features of this new Hibiscus are stable and reproduced true to type in successive generations.

BRIEF SUMMARY OF THE INVENTION

The cultivar ‘Panama Bronze’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperatures 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 ‘Panama Bronze:’

• • 1. Bronze color of new foliage in high light;
  • 2. Deeply cut foliage;
  • 3. Stable foliage color;
  • 4. Very large flowers;
  • 5. Flowers heavily during short days (November to April) in zone 10; and
  • 3. Thrives in hot and humid conditions.

Plants of the new Hibiscus can be compared to plants of the female parent, the cultivar ‘Panama Red.’ Plants of the new Hibiscus differ from ‘Panama Red’ in the following characteristics:

• • 1. Plants of the new Hibiscus display an intense bronze color of new foliage under full sun (high light) conditions, compared to the female parent that shows a nearly blackish-purple under full sun (high light) conditions.
  • 2. Plants of the new Hibiscus have flowers that are one third larger compared to the female parent.
  • 3. Plants of the new Hibiscus have more deeply cut and elongated foliage compared to the female parent.
  • 4. Plants of the new Hibiscus are less dense compared to the female parent.

Plants of the new Hibiscus can be compared to plants of the male parent, the Hibiscus radiatus. Plants of the new Hibiscus differ from Hibiscus radiatus in the following characteristics:

• • 1. Plants of the new Hibiscus display an intense bronze color of new foliage under full sun (high light) conditions, compared to the male parent that shows green color under full sun (high light) conditions.
  • 2. Plants of the new Hibiscus display darker and larger flowers than the male parent.
