plant named ‘HB051’

Abstract

A new and distinct cultivar of Camellia plant named ‘HB051’, characterized by its sturdy upright to outwardly branching plant habit; vigorous growth habit and rapid growth rate; freely branching habit, dense and bushy appearance; large leathery dark green-colored leaves; long flowering period; light red purple-colored semi-double to peony-type form flowers; and good garden performance including tolerance to full sunlight conditions.

Description

Botanical designation: Camellia hybrid.

Cultivar denomination: ‘HB051’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Camellia plant, botanically known as Camellia hybrid, and hereinafter referred to by the name ‘HB051’.

The new Camellia plant is a product of a planned breeding program conducted by the Inventors in Zhaoqing, China. The objective of the breeding program is to create new fast-growing Camellia plants that flower year-round and tolerate full sunlight.

The new Camellia plant originated from a cross-pollination conducted by the Inventors in February, 2007 in Zhaoqing, China of an unnamed seedling selection of Camellia amplexicaulis, not patented, as the female, or seed, parent with Camellia hybrid ‘Scented Swirl’, not patented, as the male, or pollen, parent. The new Camellia plant was discovered and selected by the Inventors as a single plant from within the progeny of the stated cross-pollination in a controlled environment in Zhaoqing, China in November, 2010.

Asexual reproduction of the new Camellia plant by grafting cuttings onto an unnamed selection of Camellia gaozhouensis, not patented, in a controlled greenhouse environment in Zhaoqing, China has shown that the unique features of this new Camellia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Camellia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment 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 ‘HB051’. These characteristics in combination distinguish ‘HB051’ as a new and distinct cultivar of Camellia:

• • 1. Sturdy upright to somewhat outwardly branching plant habit.
  • 2. Vigorous growth habit and rapid growth rate.
  • 3. Freely branching habit, dense and bushy appearance.
  • 4. Large leathery dark green-colored leaves.
  • 5. Long flowering period.
  • 6. Light red purple-colored semi-double to peony-type form flowers.
  • 7. Good garden performance, tolerant to full sunlight conditions.

Plants of the new Camellia differ from plants of the female parent selection primarily in the following characteristics:

• • 1. Leaves of plants of the new Camellia are slightly smaller than and not as glossy as leaves of plants of the female parent selection.
  • 2. Flowers of plants of the new Camellia are semi-double to peony-type in form whereas flowers of the female parent selection are single in form.

Plants of the new Camellia differ primarily from plants of the male parent, ‘Scented Swirl’, in the following characteristics:

• • 1. Leaves of plants of the new Camellia are larger than leaves of plants of ‘Scented Swirl’.
  • 2. Flowers of plants of the new Camellia are semi-double to peony-type in form whereas flowers of ‘Scented Swirl’ are single in form.
  • 3. Plants of the new Camellia flower for a longer period of time than plants of ‘Scented Swirl’.

Plants of the new Camellia can be compared to the plants of Camellia hybrid ‘Golden Purple Crown’, not patented. In side-by-side comparisons plants of the new Camellia differ from plants of the ‘Golden Purple Crown’ in the following characteristics:

• • 1. Leaves of plants of the new Camellia are larger than leaves of plants of ‘Golden Purple Crown’.
  • 2. Flowers of plants of the new Camellia are semi-double to peony-type in form whereas flowers of ‘Golden Purple Crown’ are peony-type in form.
  • 3. Plants of the new Camellia flower for a longer period of time than plants of ‘Golden Purple Crown’.

Plants of the new Camellia can be compared to the plants of Camellia japonica ‘Covina’, not patented. In side-by-side comparisons plants of the new Camellia differ from plants of the ‘Covina’ in the following characteristics:

• • 1. Leaves of plants of the new Camellia are larger than leaves of plants of ‘Covina’.
  • 2. Flowers of plants of the new Camellia are semi-double to peony-type in form whereas flowers of ‘Covina’ are semi-double to rose-double in form.
  • 3. Plants of the new Camellia flower for a longer period of time than plants of ‘Covina’.
