Abstract

A new and distinct cultivar of Lavandula plant named ‘Bklvdvlb’, characterized by its compact, upright and somewhat outwardly spreading plant habit; freely branching growth habit; dense and bushy plant form; early and freely flowering habit; light violet-colored flowers arranged in compact verticillasters; and good garden performance.

Description

Botanical designation: Lavandula angustifolia.
Cultivar denomination: ‘BKLVDVLB’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Lavandula plant, botanically known as Lavandula angustifolia and hereinafter referred to by the name ‘Bklvdvlb’.
The new Lavandula plant is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program was to develop new compact and early flowering Lavandula plants with uniform plant habit and attractive flower coloration.
The new Lavandula plant originated from an open-pollination in July, 2006 of Lavandula angustifolia ‘Blue River’, not patented, as the female, or seed, parent with an unknown selection of Lavandula angustifolia. The new Lavandula plant was discovered and selected by the Inventor in August, 2007 as a single flowering plant within the progeny of the stated open-pollination in a controlled outdoor nursery environment in Maasdijk, The Netherlands.
Asexual reproduction of the new Lavandula by terminal cuttings in a controlled greenhouse environment in Maasdijk, The Netherlands since September, 2007 has shown that the unique features of this new Lavandula plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Lavandula have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Bklvdvlb’. These characteristics in combination distinguish ‘Bklvdvlb’ as a new and distinct Lavandula plant:
    • 1. Compact, upright and somewhat outwardly spreading plant habit.
    • 2. Freely branching growth habit; dense and bushy plant form.
    • 3. Early and freely flowering habit.
    • 4. Light violet-colored flowers arranged in compact verticillasters.
    • 5. Good garden performance.
Plants of the new Lavandula differ from plants of the female parent, ‘Blue River’ primarily in the following characteristics:
    • 1. Plants of the new Lavandula are more vigorous than plants of ‘Blue River’.
    • 2. Plants of the new Lavandula have larger flowers than plants of ‘Blue River’.
    • 3. Flowers of plants of the new Lavandula are lighter in color than flowers of plants of ‘Blue River’.
Plants of the new Lavandula can be compared to plants of Lavandula angustifolia ‘Thumbelina’, not patented. Plants of the new Lavandula differ primarily from plants of ‘Thumbelina’ in the following characteristics:
    • 1. Plants of the new Lavandula are more freely branching than plants of ‘Thumbelina’.
    • 2. Plants of the new Lavandula flower earlier than plants of ‘Thumbelina’.
    • 3. Plants of the new Lavandula have larger flowers than plants of ‘Thumbelina’.
    • 4. Flowers of plants of the new Lavandula are lighter in color than flowers of plants of ‘Thumbelina’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Lavandula plant showing 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 Lavandula plant.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Bklvdvlb’ grown in a container.
The photograph on the second sheet is a close-up view of typical developing and fully developed flowering stems and upper and lower surfaces of leaves of ‘Bklvdvlb’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs, following observations and measurements describe plants grown during the spring and summer in 12-cm containers in a glass-covered greenhouse in Maasdijk, The Netherlands and under cultural practices which approximate those generally used in commercial Lavandula production. Plants were 23 weeks old when the photographs and description were taken. Plants were pinched one time. During the production of the plants, day temperatures ranged from 15° C. to 22° C. and night temperatures ranged from 12° C. to 16° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
