Lavender plant named ‘Silver Anouk’

Abstract

A new and distinct cultivar of Lavender plant named ‘Silver Anouk’, characterized by its compact and upright plant habit; freely branching growth habit; durable silvery green-colored leaves; freely flowering habit; large dark violet-colored flowers positioned on strong and erect peduncles; and good garden performance.

Description

Botanical designation: Lavandula stoechas.

Cultivar denomination: ‘Silver Anouk’.

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 ‘Silver Anouk’.

The new Lavender is a naturally-occurring branch mutation of the Lavandula stoechas ‘Anouk’, disclosed in U.S. Plant Pat. No. 16,685. The new Lavender was discovered and selected by the Inventor on a single plant within a population of plants of ‘Anouk’ in a controlled outdoor nursery environment in Nuis, The Netherlands in June, 2006.

Asexual reproduction of the new Lavender by terminal cuttings in a controlled greenhouse environment in Sappemeer, The Netherlands since August, 2006, 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 new Lavender have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength 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. These characteristics in combination distinguish ‘Silver Anouk’ as a new and distinct cultivar of Lavender:

• • 1. Compact and upright plant habit.
  • 2. Freely branching growth habit.
  • 3. Durable silvery green-colored leaves.
  • 4. Freely flowering habit.
  • 5. Large dark violet-colored flowers positioned on strong and erect peduncles.
  • 6. Good garden performance.

Plants of the new Lavender differ from plants of the parent, ‘Anouk’, primarily in leaf color as plants of ‘Anouk’ have greyed green-colored leaves.

Plants of the new Lavender can be compared to plants of the Lavender ‘Alexandra’, not patented. In side-by-side comparisons conducted in Sappemeer, The Netherlands, plants of the new Lavender differed from plants of ‘Alexandra’ in the following characteristics:

• • 1. Plants of the new Lavender had stronger and more durable stems than plants of ‘Alexandra’.
  • 2. Plants of the new Lavender and ‘Alexandra’ differed in leaf color as plants of ‘Alexandra’ had greyed green-colored leaves.
  • 3. Plants of the new Lavender had shorter flower bracts than plants of ‘Alexandra’.

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 Boskoop, 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 two times 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.
