Description

Botanical designation: Lavandula angustifolia.

Cultivar denomination: ‘Blue Royalty’.

CROSS-REFERENCED TO CLOSELY RELATED APPLICATIONS

Title: Lavender Plant Named ‘Silver Royalty’.

Applicant: Lammert Koning.

Filed: Concurrently with this application (U.S. Plant patent application Ser. No. 12/228,285).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lavender plant, botanically known as Lavandula angustifolia, and hereinafter referred to by the name ‘Blue Royalty’.

The new Lavender plant is a product of a planned breeding program conducted by the Inventor in Nuis, The Netherlands. The objective of the breeding program was to develop new strong Lavender cultivars with attractive plant form and flower coloration.

The new Lavender plant originated from a cross-pollination made by the Inventor in July, 2004 of a proprietary selection of Lavandula angustifolia identified as code number 1755, not patented, as the female, or seed, parent with Lavandula angustifolia ‘Hidcote’, not patented, as the male, or pollen, parent. The new Lavender plant was discovered and selected by the Inventor in August, 2005 as a single flowering plant within the progeny of the stated cross-pollination in a controlled outdoor nursery environment in Nuis, The Netherlands.

Asexual reproduction of the new Lavender by terminal cuttings in a controlled greenhouse environment in Sappemeer, The Netherlands since November, 2005, has shown that the unique features of this new Lavender plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Lavender 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 the new Lavender plant. These characteristics in combination distinguish ‘Blue Royalty’ as a new and distinct cultivar of Lavender:

- 1. Compact, upright and somewhat outwardly spreading plant habit.
- 2. Freely branching growth habit.
- 3. Durable green-colored leaves.
- 4. Freely flowering habit.
- 5. Large dark purple-colored flowers positioned on long and strong peduncles.
- 6. Good garden performance.

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

- 1. Plants of the new Lavender have shorter lateral branches than plants of the female parent selection.
- 2. Plants of the new Lavender and the female parent selection differ in leaf color.
- 3. Plants of the new Lavender have thicker peduncles than plants of the female parent selection.

Plants of the new Lavender differ from plants of the male parent, ‘Hidcote’, in the following characteristics:

- 1. Plants of the new Lavender are more freely branching than plants of ‘Hidcote’.
- 2. Plants of the new Lavender have larger leaves than plants of ‘Hidcote’.
- 3. Plants of the new Lavender have larger flowers than plants of ‘Hidcote’.
- 4. Plants of the new Lavender are more freely flowering and flower for a longer period of time than plants of ‘Hidcote’.

Plants of the new Lavender can be compared to plants of Lavandula lannatum×Lavandula angustifolia ‘Silver Royalty’, disclosed in a U.S. Plant Patent application filed concurrently. Plants of the new Lavender differ from plants of ‘Silver Royalty’ in the following characteristics:

- 1. Plants of the new Lavender and ‘Silver Royalty’ differ in leaf color as plants of ‘Silver Royalty’ have greyed green-colored leaves.
- 2. Plants of the new Lavender and ‘Silver Royalty’ differ in flower color as plants of ‘Silver Royalty’ have dark blue-colored flowers.

Plants of the new Lavender can also be compared to plants of Lavandula angustifolia ‘Buena Vista’, not patented. Plants of the new Lavender differ from plants of ‘Buena Vista’ in the following characteristics:

- 1. Plants of the new Lavender and ‘Buena Vista’ differ in leaf color as plants of ‘Buena Vista’ have greyed green-colored leaves.
- 2. Plants of the new Lavender are more freely flowering than plants of ‘Buena Vista’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Lavender plant. These photographs show 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 colors of the new Lavender.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Blue Royalty’ grown in a container.

The photograph at the top of the second sheet is a close-up view of a typical inflorescence of ‘Blue Royalty’.

The photograph at the bottom of the second sheet is a close-up view of the upper surface of a typical leaf of ‘Blue Royalty’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs, following observations and measurements describe plants grown in 14-cm containers in Paterswolde, The Netherlands during the spring in an outdoor nursery and under conditions and practices which approximate those generally used in commercial Lavender production. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched once and were one year old when the photographs and description were taken. During the production of the plants, day temperatures ranged from 4° C. to 20° C. and night temperatures ranged from 0° C. to 14° C.
