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 ‘HA012’.

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 ‘Kramer's Supreme’, 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 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 ‘HA012’. These characteristics in combination distinguish ‘HA012’ as a new 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. Relatively large light red-colored single-type 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 oblong in shape whereas leaves of plants of the female parent selection are lanceolate in shape.
  • 2. Leaves of plants of the new Camellia have serrate margins whereas leaves of plants of the female parent selection have entire margins.
  • 3. Flowers of plants of the new Camellia are slightly fragrant whereas flowers of the female parent selection are not fragrant.

Plants of the new Camellia differ primarily from plants of the male parent, ‘Kramer's Supreme’, in the following characteristics:

• • 1. Margins of leaves of plants of the new Camellia are not as serrate as margins of leaves of plants of ‘Kramer's Supreme’.
  • 2. Plants of the new Camellia and ‘Kramer's Supreme’ differ in flower color as plants of ‘Kramer's Supreme’ have darker red-colored flowers.
  • 3. Plants of the new Camellia flower multiple times during the year whereas plants of plants of ‘Kramer's Supreme’ flower once a year.

Plants of the new Camellia can be compared to plants of Camellia changii X Camellia japonica ‘HA011’, disclosed in a U.S. Plant patent application Ser. No. 15/530,356 filed concurrently. Plants of the new Camellia and ‘HA011’ differ primarily in flower color as plants of ‘HA011’ have red and light pink-colored flowers.

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

• • 1. Flowers of plants of the new Camellia are faintly fragrant whereas flowers of plants of ‘Hong Lu Zhen’ are not fragrant.
  • 2. Plants of the new Camellia flower multiple times during the year whereas plants of plants of ‘Hong Lu Zhen’ only flower one time each year.
