plant named ‘HA351’

Abstract

A new and distinct cultivar of Camellia plant named ‘HA351’, characterized by its sturdy upright plant habit; rapid growth habit; freely branching habit; dense and bushy appearance; leathery dark green-colored leaves; flowering during the summer, autumn and winter; large bright red-colored semi-double flowers; and good garden performance.

Description

Botanical designation: Camellia changii X Camellia japonica.

Cultivar denomination: ‘HA351’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Camellia plant, botanically known as Camellia changii X Camellia japonica, and hereinafter referred to by the name ‘HA351’.

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 October, 2006 in Zhaoqing, China of an unnamed seedling selection of Camellia changii, not patented, as the female, or seed, parent with Camellia japonica ‘Bob Hope’, 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 September, 2011.

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 since 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 ‘HA351’. These characteristics in combination distinguish ‘HA351’ as anew and distinct cultivar of Camellia:

• • 1. Sturdy upright plant habit.
  • 2. Rapid growth habit.
  • 3. Freely branching habit, dense and bushy appearance.
  • 4. Leathery dark green-colored leaves.
  • 5. Flowering during the summer, autumn and winter.
  • 6. Large bright red-colored semi-double 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 obovate in shape whereas leaves of plants of the female parent selection are lanceolate in shape.
  • 2. Leaves of plants of the new Camellia have sparsely serrate margins whereas leaves of plants of the female parent selection have entire margins.
  • 3. Flowers of plants of the new Camellia are larger than flowers of the female parent selection.

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

• • 1. Leaves of plants of the new Camellia have sparsely serrate margins whereas leaves of plants of ‘Bob Hope’ have densely serrate margins.
  • 2. Plants of the new Camellia and ‘Bob Hope’ differ in flower color as plants of ‘Bob Hope’ have purplish red-colored flowers.
  • 3. Plants of the new Camellia flower multiple times during the year whereas plants of plants of ‘Bob Hope’ flower once a year.

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

• • 1. Leaves of plants of the new Camellia have sparsely serrate margins whereas leaves of plants of ‘Terrell Weaver’ have densely serrate margins.
  • 2. Plants of the new Camellia flower multiple times during the year whereas plants of plants of ‘Terrell Weaver’ flower once a year.
