plant named ‘Green 02-004’

Abstract

A new cultivar of Camellia sasanqua named ‘Green 02-004’, that is characterized by its compact, dense, and rounded plant habit, its dark green foliage, its double flowers that are white in color, its very floriferous and long-lasting bloom habit, and its resistance to root rot (Phytophora cinnamomi) and dieback (Glomerella cingulata).

Description

Botanical classification: Camellia sasanqua.

Variety denomination: ‘Green 02-004’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Camellia plant, botanically known as Camellia sasanqua, ‘Green 02-004’. The new cultivar will be referred to hereafter by its cultivar name, ‘Green 02-004’. ‘Green 02-004’ is a new perennial shrub grown for container and landscape use.

‘Green 02-004’ was derived from an ongoing breeding program conducted by the Inventor in Fairhope, Ala., USA since 1992. The objectives of the breeding program are to develop new cultivars of Camellia sasanqua with compact plant habits, vigorous growth habits, improved disease resistance, and extended bloom periods. ‘Green 02-004’ originated as a seedling that arose from seed planted from open pollination of the Camellia sasanqua cultivar ‘Shishi Gashira’ (not patented) as the female parent in 2000 in Fairhope, Ala. The male parent is unknown. The new Camellia was selected as a single unique plant in Fall of 2004.

Asexual reproduction of the new cultivar was first accomplished by stem cuttings by the Inventor in 2004 in Fairhope, Ala. Asexual propagation by stem cuttings has determined that the characteristics of this cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new Camellia. These attributes in combination distinguish ‘Green 02-004’ as a new and distinct cultivar of Camellia.

• • 1. ‘Green 02-004’ exhibits a compact, dense, and rounded plant habit.
  • 2. ‘Green 02-004’ exhibits dark green foliage.
  • 3. ‘Green 02-004’ exhibits double flowers that are white in color.
  • 4. ‘Green 02-004’ exhibits a very floriferous and long-lasting bloom habit.
  • 5. ‘Green 02-004’ exhibits resistance to root rot (Phytophora cinnamomi) and dieback (Glomerella cingulata).

The female parent of ‘Green 02-004’, ‘Shishi Gashira’, differs from ‘Green 02-004’ in having flowers with fewer petals that are rose pink in color and in having flowers that are more asymetrically semi-double in form. ‘Green 02-004’ can also be compared to the Camellia cultivars ‘Green 94-010’ (U.S. Plant Pat. No. 20,454) and ‘Snow Flurry’ (not patented). Both culivars are similar to ‘Green 02-004’ in having flowers that are white in color. ‘Green 94-010’ differs from ‘Green 02-004’ in having a less compact plant habit and in having a shorter bloom season. ‘Snow Flurry’ differs from ‘Green 02-004’ in having an open plant habit, in having leaves that are lighter in color, in having a less uniform growth habit, and in having a shorter bloom season.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Camellia. The photographs were taken of a 32 month-old plant of ‘Green 02-004’, as grown outdoors in a trial garden in Fairhope, Ala.

The photograph in FIG. 1 provides a side-view of the plant habit of ‘Green 02-004’.

The photograph in FIG. 2 provides a close-up view of a flower of ‘Green 02-004’.

The photograph in FIG. 3 provides a close-up view of the buds and a flower of ‘Green 02-004’.

The colors in the photographs are as close as possible with digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the new Camellia.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of three year-old plants of the new cultivar as grown ourtdoors in three-gallon containers in Fairhope, Ala. Plants were grown under 30% shade cloth with average day temperatures between 10 to 24° C. (50 to 75° F.) and average night temperatures between −1 to 10° C. (30 to 50° F.). The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
