Abstract

A new and distinct cultivar of Lavender plant named ‘Barcelona Rose’, characterized by its compact, upright and mounded plant habit; freely branching, dense and bushy plant form; and violet-colored flowers with showy light purple-colored terminal flower bracts.

Description

Botanical classification/cultivar designation: Lavandula stoechas cultivar Barcelona Rose.

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 ‘Barcelona Rose’.

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 and freely branching Lavender cultivars with large and attractive flowers and good garden performance.

The new Lavender originated from a cross-pollination made by the Inventor in August, 1999, of the Lavandula stoechas cultivar Madrid Pink, not patented, as the female, or seed, parent with an unknown selection of Lavandula stoechas, not patented, 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 cross-pollination grown in a controlled environment in Kulnura, New South Wales, Australia in 1999.

Asexual reproduction of the new cultivar by terminal cuttings taken at Kulnura, New South Wales, Australia, since October, 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 Barcelona Rose 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 ‘Barcelona Rose’. These characteristics in combination distinguish ‘Barcelona Rose’ as a new and distinct cultivar:

- 1. Compact, upright and mounded plant habit.
- 2. Freely branching, dense and bushy plant form.
- 3. Violet-colored flowers with showy light purple-colored terminal flower bracts.

Plants of the new Lavender differ from plants of the female parent, the cultivar Madrid Pink, in the following characteristics:

- 1. Plants of the new Lavender are more dense than plants of the cultivar Madrid Pink.
- 2. Plants of the new Lavender have shorter peduncles than plants of the cultivar Madrid Pink.
- 3. Plants of the new Lavender flower later than plants of the cultivar Madrid Pink.

Plants of the new Lavender can be compared to plants of the cultivar Kew Red, not patented. In side-by-side comparisons conducted by the Inventor in Kulnura, New South Wales, Australia, plants of the new Lavender differed from plants of the cultivar Kew Red in the following characteristics:

- 1. Plants of the new Lavender were denser and bushier than plants of the cultivar Kew Red.
- 2. Plants of the new Lavender had longer terminal flower bracts than plants of the cultivar Kew Red.
- 3. Plants of the new Lavender flowered later than plants of the cultivar Kew Red.

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 more accurately describe the actual colors of the new Lavender.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Barcelona Rose’ grown in a one-gallon container.

The photograph at the top of the sheet comprises a close-up view of typical leaves and inflorescences of ‘Barcelona Rose’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 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 winter in a polycarbonate-covered greenhouse in Lompoc, Calif. for about 37 weeks in 1-gallon containers. During the production of the plants, day temperatures ranged from 18 to 24° C., night temperatures ranged from 16 to 18° C., and light levels ranged from 4,000 to 8,000 foot-candles.
