plant named ‘HOHB’

Abstract

A new and distinct cultivar of Ternstroemia plant named ‘HOHB’, characterized by its compact, upright and outwardly spreading plant form; uniformly mounded habit; dense and bushy plant habit; vigorous growth habit; leaves that are initially bright yellow in the spring, becoming golden bronze in the summer and green highlighted with yellow in the late autumn and winter; and good garden performance.

Description

Botanical designation: Ternstroemia gymnanthera.

Cultivar denomination: ‘HOHB’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Ternstroemia, botanically known as Ternstroemia gymnanthera and hereinafter referred to by the name ‘HOHB’.

The new Ternstroemia is a product of a planned breeding program conducted by the Inventors in Seneca, S.C. The objective of the breeding program is to create new Ternstroemia cultivars with attractive plant form and leaf coloration.

The new Ternstroemia originated from a self-pollination made by the Inventors in 1997, in Seneca, S.C. of an unnamed selection of Ternstroemia gymnanthera, not patented. The new Ternstroemia was discovered and selected by the Inventors as a single plant from within the progeny of the stated self-pollination in a controlled outdoor nursery environment in Seneca, S.C. in 1998.

Asexual reproduction of the new cultivar by semi-hardwood and hardwood stem cuttings in Seneca, S.C. since November, 2000 has shown that the unique features of this new Ternstroemia plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Ternstroemia have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and/or light intensity without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘HOHB’. These characteristics in combination distinguish ‘HOHB’ as a new and distinct cultivar of Ternstroemia:

• • 1. Compact, upright and outwardly spreading plant form; uniformly mounded habit.
  • 2. Dense and bushy plant habit.
  • 3. Vigorous growth habit.
  • 4. Leaves that are initially bright yellow in the spring, becoming golden bronze in the summer and green highlighted with yellow in the late autumn and winter.
  • 5. Good garden performance.

Plants of the new Ternstroemia can be compared to plants of the parent selection. Plants of the new Ternstroemia differ from plants of the parent selection in the following characteristics:

• • 1. Plants of the new Ternstroemia are more compact than and not as vigorous as plants of the parent selection.
  • 2. Plants of the new Ternstroemia are denser than and not as open as plants of the parent selection.
  • 3. During the spring and summer, plants of the new Ternstroemia have bright yellow to golden bronze-colored leaves whereas plants of the parent selection have green-colored leaves.

Plants of the new Ternstroemia can be compared to the plants of Ternstroemia gymnanthera ‘Variegata’, not patented. In side-by-side comparisons conducted in Seneca, S.C., plants of the new Ternstroemia differed from plants of ‘Variegata’ in the following characteristics:

• • 1. Plants of the new Ternstroemia were more compact than and not as upright as plants of ‘Variegata’.
  • 2. Plants of the new Ternstroemia were denser than and not as open as plants of ‘Variegata’.
  • 3. During the spring and summer, plants of the new Ternstroemia had bright yellow to golden bronze-colored leaves whereas plants of ‘Variegata’ had green, gray and cream-colored leaves tinged with pink.

Plants of the new Ternstroemia can be compared to the plants of Ternstroemia gymnanthera ‘Conthery’, disclosed in U.S. Plant Pat. No. 11,735. In side-by-side comparisons conducted in Seneca, S.C., plants of the new Ternstroemia differed from plants of ‘Conthery’ in the following characteristics:

• • 1. Plants of the new Ternstroemia were more compact than and not as upright as plants of ‘Conthery’.
  • 2. Plants of the new Ternstroemia were not as vigorous as plants of ‘Conthery’.
  • 3. During the spring and summer, plants of the new Ternstroemia had bright yellow to golden bronze-colored leaves whereas plants of ‘Conthery’ had reddish bronze leaves that changed to green in the late summer.
