Abstract

A new and distinct cultivar of Lavandula angustifolia plant named ‘KERBEEPOWER’ is disclosed, characterized by a compact, bushy plant, with short peduncles, and large flower spikes. Flowers are violet-blue. The new variety is a Lavandula angustifolia, suitable for outdoor landscape and container use.

Description

Latin name of the genus and species: Lavandula angustifolia.

Variety denomination: ‘KERBEEPOWER’.

BACKGROUND OF THE INVENTION

The new cultivar is the product of a planned breeding program under the direction of the inventors, David Kerley, Priscilla Kerley, Sarah Kerley, and Timothy Kerley, all citizens of the United Kingdom. The objective of the breeding program was to produce new Lavandula angustifolia cultivars for commercial ornamental purposes. During the Summer of 2008, the inventors performed an open pollination of several unnamed, unpatented proprietary Lavandula angustifolia varieties with the seed parent Lavandula angustifolia ‘Kerlavgem’, U.S. Plant Pat. No. 23,001. This resulted in the selection of the new variety ‘KERBEEPOWER’ in July 2009. The breeding program and selection all took place at a commercial nursery in Cambridge, the United Kingdom.

Asexual reproduction of the new cultivar ‘KERBEEPOWER’ was first performed in Cambridge, UK in August 2009 by terminal vegetative cuttings and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘KERBEEPOWER’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘KERBEEPOWER’. These characteristics in combination distinguish ‘KERBEEPOWER’ as a new and distinct Lavandula cultivar:

- 1. Compact, bushy plants.
- 2. Short peduncles.
- 3. Large flower spikes.
- 4. Violet-blue flowers.

PARENTAL COMPARISON

Plants of the new cultivar ‘KERBEEPOWER’ are similar to plants of seed parent in most horticultural characteristics, however, plants of the new cultivar differ in the following:

- 1. Plants of ‘KERBEEPOWER’ are much smaller and shorter than plants of ‘KERLAVANGEM’.
- 2. Foliage of the new variety is wider than that of ‘KERLAVANGEM’.
- 3. Flower color of the new variety is a different shade of violet-blue.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘KERBEEPOWER’ are similar to plants of the unpatented variety Lavandula angustifolia ‘Hidcote’ in most horticultural characteristics, however, plants of the new cultivar ‘KERBEEPOWER’ differ in the following:

- 1. The new variety is a shorter plant than this comparator.
- 2. Flowers of the new variety are more violet-blue, while flowers of this comparator are violet.

Plants of the new cultivar ‘KERBEEPOWER’ are similar to plants of the unpatented variety Lavandula angustifolia ‘BeeZee Dark Blue’ in most horticultural characteristics, however, plants of the new cultivar ‘KERBEEPOWER’ differ in the following:

- 1. The new variety has 5 buds subtending from the bracts, while this comparator has 3.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘KERBEEPOWER’ grown outdoors in Cambridge, UK. The plant is approximately 1 year old shown in an approximately 10 inch pot.

FIG. 2 illustrates a close-up view of a typical inflorescence.

FIG. 3 illustrates a comparison with the well-known commercial variety ‘Bee Zee Dark Blue’. ‘KERBEEPOWER’ is the plant on the left side of the photo, ‘Bee Zee Dark Blue’ is on the right.

FIG. 4 illustrates a comparison with the commercial variety ‘Hidcote’. ‘KERBEEPOWER’ is the plant on the left side of the photo, ‘Hidcote’ is on the right.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
