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 ‘AGRI812’.
The new Lavandula plant is a product of a planned breeding program conducted by the Inventor in De Lier, 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 a cross-pollination in July 2015 of a proprietary selection of Lavandula stoechas identified as code designation agri 279, not patented, as the female, or seed, parent with a proprietary selection of Lavandula stoechas identified as code designation agri 425, not patented, 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 cross-pollination in a controlled environment in De Lier, The Netherlands in April 2016.
Asexual reproduction of the new Lavandula plant by terminal cuttings in a controlled greenhouse environment in De Lier, The Netherlands since May 2016 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 ‘AGRI812’ as a new and distinct Lavandula plant:
- 1. Upright to outwardly and broadly spreading plant habit.
- 2. Freely branching growth habit.
- 3. Freely flowering habit.
- 4. Relatively large dark violet-colored flowers and purple-colored terminal flower bracts positioned on strong and erect peduncles.
- 5. Long flowering period.
- 6. Good garden performance.
Plants of the new Lavandula differ primarily from plants of the female parent selection primarily in leaf size and color as plants of the new Lavandula have broader and more greyed-colored leaves than plants of the female parent selection.
Plants of the new Lavandula differ primarily from plants of the male parent selection primarily in growth habit as plants of the new Lavandula are more outwardly spreading than and not as upright as plants of the male parent selection. In addition, plants of the new Lavandula have larger terminal flower bracts than plants of the male parent selection.
Plants of the new Lavandula can be compared to plants of the Lavandula stoechas ‘Dark Knight’, not patented. In side-by-side comparisons, plants of the new Lavandula differ primarily from plants of ‘Dark Knight’ in the following characteristics:
- 1. Plants of the new Lavandula are more outwardly spreading than and not as upright as plants of ‘Dark Knight’.
- 2. Plants of the new Lavandula have larger flowers than plants of ‘Dark Knight’.
- 3. Plants of the new Lavandula have larger terminal flower bracts than plants of ‘Dark Knight’.
Plants of the new Lavandula can also be compared to plants of the Lavandula stoechas ‘AGRI811’, disclosed in U.S. Plant Pat. No. 33,173. In side-by-side comparisons, plants of the new Lavandula differ primarily from plants of ‘AGRI811’ in the following characteristics:
- 1. Plants of the new Lavandula are more freely branching than plants of ‘AGRI811’.
- 2. Plants of the new Lavandula have darker green-colored leaves than plants of ‘AGRI811’.
- 3. Plants of the new Lavandula are not as freely flowering as plants of ‘AGRI811’.
- 4. Plants of the new Lavandula have more terminal flower bracts per flower than plants of ‘AGRI811’.

DETAILED BOTANICAL DESCRIPTION
Plants used in the aforementioned photographs and following detailed description were grown in 12-cm containers during the spring in an outdoor nursery in Maasdijk, The Netherlands and under cultural practices typical of commercial Lavandula production. Plants were pinched four weeks after planting and were six months old when the photographs and description were taken. During the production of the plants, day temperatures ranged from 18C to 20C and night temperatures ranged from 8C to 10C.
