Abstract

A new and distinct cultivar of Lavender plant named ‘Cocwob’characterized by its compact, upright, outwardly spreading and mounded plant habit; freely branching habit, dense and bushy plant form; early flowering habit; and dark purple-colored flowers with white-colored terminal flower bracts.

Description

Botanical designation: Lavandula stoechas.

Cultivar denomination: ‘Cocwob’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Lavender plant, botanically known as Lavandula stoechas, and hereinafter referred to by the name ‘Cocwob’.

The new Lavender is a product of a planned breeding program conducted by the Inventor in Kulnura, New South Wales, Australia. The objective of the breeding program was to create new compact, mounded and freely branching Lavender cultivars with attractive flowers and good garden performance.

The new Lavender originated from an open-pollination in 1999 of a proprietary selection of Lavandula stoechas identified as code number 97-05, not patented, as the female, or seed, parent with an unknown selection of Lavandula stoechas, as the male, or pollen, parent. The new Lavender was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination grown in a controlled environment in Kulnura, New South Wales, Australia in September, 2000.

Asexual reproduction of the new cultivar by terminal cuttings at Kulnura, New South Wales, Australia, since 2000, has shown that the unique features of this new Lavender are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Cocwob have not been observed under all possible environmental conditions. 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 ‘Cocwob’. These characteristics in combination distinguish ‘Cocwob’ as a new and distinct cultivar:

- 1. Compact, upright, outwardly spreading and mounded plant habit.
- 2. Freely branching habit, dense and bushy plant form.
- 3. Early flowering habit.
- 4. Dark purple-colored flowers with white-colored terminal flower bracts.

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

- 1. Plants of the new Lavender are more uniform in plant habit than plants of the female parent selection.
- 2. Plants of the new Lavender and the female parent selection differ in flower coloration.
- 3. Plants of the new Lavender and the female parent selection differ in flower bract coloration.

Plants of the new Lavender can be compared to plants of the Lavender cultivar Madrid Blue, not patented. In side-by-side comparisons conducted in Kulnura, New South Wales, Australia, plants of the new Lavender differed from plants of the cultivar Madrid Blue primarily in flower and terminal bract coloration, inflorescence size, terminal flower bract size and peduncle length.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Lavender.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Cocwob’ grown in a container.

The photograph at the bottom of the sheet comprises a close-up view of typical inflorescences of ‘Cocwob’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1999 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the aforementioned photographs and following description were grown under conditions which closely approximate commercial production conditions during the spring in a glass-covered greenhouse in Kulnura, New South Wales, Australia for about four to six months in 15-cm containers.
