Description

Latin name of the genus and species: Lavandula angustifolia.

Variety denomination: ‘KERLAVANHAZE’.

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 and Timothy Kerley, all citizen of the United Kingdom. The objective of the breeding program was to produce new Lavandula angustifolia cultivars for commercial ornamental purposes. The breeding program consisted of organizing groups of unnamed, unpatented commercial Lavandula angustifolia varieties for open pollination. The seeds from these unnamed parents were collected and planted out, resulting in the selection of the new variety ‘Kerlavanhaze’ in the Spring of 2001. The breeding program and selection all took place at a commercial nursery in Cambridge, the United Kingdom.

Asexual reproduction of the new cultivar ‘KERLAVANHAZE’ by vegetative cuttings was first performed in Cambridge, UK in the Autumn of 2001 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 ‘KERLAVANHAZE’ 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 ‘KERLAVANHAZE’ These characteristics in combination distinguish ‘KERLAVANHAZE’ as a new and distinct Lavandula cultivar:

    • 1. Compact plant growth.
    • 2. Short peduncles.
    • 3. Numerous side breaks, forming a bushy overall plant.
    • 4. Moderately fine foliage.
    • 5. Pale lavender-blue bud coloration.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘KERLAVANHAZE’ are similar to plants of the unpatented variety Lavandula angustifolia ‘Hidcote’ in most horticultural characteristics, however, plants of the new cultivar ‘KERLAVANHAZE’ are consistently overall more compact than ‘Hidcote’ with an overall more controlled growth habit more suitable for small commercial pots. Additionally, ‘KERLAVANHAZE’ produces a shorter, broader flowering spike, a lighter flower bud color on a stronger peduncle. Finally, foliage of ‘KERLAVANHAZE’ is narrower and shorter than foliage of ‘Hidcote.’

Plants of the new cultivar ‘KERLAVANHAZE’ can also be compared to the commercial variety Lavandula angustifolia ‘Blue Cushion’ U.S. Plant Pat. No. 9,119. Plants of ‘KERLAVANHAZE’ are similar to plants of ‘Blue Cushion’ in most horticultural characteristics, however, plants of the new cultivar have a shorter, thicker peduncle, with a broader, denser flower spike. Additionally, the flower bud color of ‘KERLAVANHAZE’ is darker than the flower buds of ‘Blue Cushion’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color typical plants of ‘KERLAVANHAZE’ grown outdoors in Cambridge, UK. Plants are approximately 8 months old shown in an approximately 4 inch pot. The photograph was 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.
