BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Lavandula plant, botanically known as Lavandula stoechas, commonly referred to as Lavender and hereinafter referred to by the name ‘Dolavladibini’.
The new Lavandula plant is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program was to develop new unique Lavandula plants with long flowering period and attractive plant form and flower coloration.
The new Lavandula plant originated from an open-pollination in April, 2016 of a proprietary selection of Lavandula stoechas identified as code number LV15-000115-001, not patented, as the female, or seed, parent with an unknown selection of Lavandula stoechas as the male, or pollen, parent. The new Lavandula plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Aalsmeer, The Netherlands in April, 2017.
Asexual reproduction of the new Lavandula plant by terminal cuttings in a controlled greenhouse environment in Aalsmeer, The Netherlands since June, 2017 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 combinations of 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 the new Lavandula plant. These characteristics in combination distinguish ‘Dolavladibini’ as a new and distinct Lavandula plant:
- 1. Relatively compact, upright and uniform plant habit.
- 2. Moderately vigorous growth habit.
- 3. Freely branching habit.
- 4. Early and freely flowering habit.
- 5. Dark purple-colored flowers positioned on strong peduncles.
- 6. Good container and garden performance.
Plants of the new Lavandula differ primarily from plants of the female parent selection primarily in inflorescence size as plants of the new Lavandula have larger inflorescences than plants of the female parent selection.
Plants of the new Lavandula can be compared to plants of the Lavandula stoechas ‘Anouk’, disclosed in U.S. Plant Pat. No. 16,685. In side-by-side comparisons, plants of the new Lavandula differ primarily from plants of ‘Anouk’ in plant size as plants of the new Lavandula are more compact than and not as tall as plants of ‘Anouk’. In addition, plants of the new Lavandula flower earlier than plants of ‘Anouk’.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph illustrates 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 photograph 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 is a side perspective view of a typical flowering plant of ‘Dolavladibini’ grown in a container.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations and measurements describe plants grown in 17-cm containers in Aalsmeer, The Netherlands during the summer initially in a glass-covered greenhouse and finished in an outdoor nursery and under conditions and cultural practices which approximate those generally used in commercial Lavandula plant production. During the production of the plants, day temperatures averaged 21° C. and night temperatures averaged 15° C. Plants were 20 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Second Edition, except where general terms of ordinary dictionary significance are used. Measurements represent averages for typical flowering plants.
