Claims
It is claimed:
1. A new and distinct Lavandula plant named `Bklvdvlb` as
illustrated and described.
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.degree. C. to 22.degree. C. and night
temperatures ranged from 12.degree. C. to 16.degree. 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.
