Description

Botanical designation: Lavandula lannatum×Lavandula angustifolia.

Cultivar denomination: ‘Silver Royalty’.

CROSS-REFERENCED TO CLOSELY RELATED APPLICATIONS

Title: Lavender Plant Named ‘Blue Royalty’.

Applicant: Lammert Koning.

Filed: Concurrently with this application (U.S. Plant patent application Ser. No. 12/228,286).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lavender plant, botanically known as Lavandula lannatum×Lavandula angustifolia, and hereinafter referred to by the name ‘Silver 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 an unnamed selection of Lavandula lannatum, not patented, as the female, or seed, parent with an unnamed selection of Lavandula angustifolia, 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 ‘Silver 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 greyed green-colored leaves.
  • 4. Freely flowering habit.
  • 5. Large blue-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. Leaves of plants of the new Lavender are not as pubescent as leaves of plants of the female parent selection.
  • 2. Plants of the new Lavender have more compact inflorescences than plants of the female parent selection.
  • 3. Plants of the new Lavender are more freely flowering than plants of the female parent selection.

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

• • 1. Plants of the new Lavender and male parent selection differ in leaf color as plants of male parent selection have green-colored leaves.
  • 2. Plants of the new Lavender and male parent selection differ in flower color as plants of male parent selection have dark purple-colored flowers.

Plants of the new Lavender can be compared to plants of Lavandula angustifolia ‘Sawyers’, not patented. Plants of the new Lavender differ in flowering habit as plants of the new Lavender are more freely flowering than plants of ‘Sawyers’.

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.
