Petunia plant named ‘Lanbor’
A new and distinct cultivar of Petunia plant named ‘Lanbor’, characterized by its cascading plant habit; freely branching habit; freely and continuous flowering habit; numerous single flowers that are light purple in color with dark purple-colored centers; good garden performance; and resistance to Powdery Mildew.
Botanical classification/cultivar designation: Petunia×hybrida cultivar Lanbor.BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida, and hereinafter referred to by the cultivar name Lanbor.
The new Petunia is a product of a planned breeding program conducted by the Inventor in West Pugwash, Nova Scotia, Canada. The objective of the breeding program is to create new disease-resistant Petunias with cascading plant habit and attractive flower colors.
The new Petunia originated from a cross-pollination made by the Inventor in March, 2001 of an unnamed seedling selection of Petunia×hybrida, not patented, as the female, or seed parent, with an unnamed seedling selection of Petunia×hybrida, not patented, as the male, or pollen parent. The new Petunia was discovered and selected as a single plant from the resulting progeny of the stated cross-pollination in June, 2001 in West Pugwash, Nova Scotia, Canada, on the basis of its plant habit and attractive flower coloration.
Asexual reproduction of the new cultivar by terminal vegetative cuttings since June, 2001, in West Pugwash, Nova Scotia, Canada has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.SUMMARY OF THE INVENTION
Plants of the cultivar Lanbor have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and daylength without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Lanbor’. These characteristics in combination distinguish ‘Lanbor’ as a new and distinct cultivar:
- 1. Cascading plant habit.
- 2. Freely branching habit.
- 3. Freely and continuous flowering habit.
- 4. Numerous single flowers that are light purple in color with dark purple-colored centers.
- 5. Good garden performance.
- 6. Resistant to Powdery Mildew.
In side-by-side comparisons conducted in West Pugwash, Nova Scotia, Canada, plants of the new Petunia differed from plants of the female parent selection in the following characteristics:
- 1. Plants of the new Petunia were not as vigorous as plants of the female parent selection.
- 2. Plants of the new Petunia and the female parent selection differed in flower coloration.
- 3. Plants of the new Petunia were resistant to Powdery Mildew whereas plants of the female parent selection were not resistant to Powdery Mildew.
In side-by-side comparisons conducted in West Pugwash, Nova Scotia, Canada, plants of the new Petunia differed from plants of the male parent selection in the following characteristics:
- 1. Plants of the new Petunia were more compact than plants of the male parent selection.
- 2. Plants of the new Petunia had smaller flowers than plants of the male parent selection.
Plants of the new Petunia can be compared to plants of the cultivar Surfinia Blue Vein, not patented. In side-by-side comparisons conducted in West Pugwash, Nova Scotia, Canada, plants of the new Petunia differed from plants of the cultivar Surfinia Blue Vein in the following characteristics:
- 1. Plants of the new Petunia were more uniform and not as vigorous as plants of the cultivar Surfinia Blue Vein.
- 2. Plants of the new Petunia and the cultivar Surfina Blue Vein differed in flower coloration.
The accompanying colored photograph illustrates the overall appearance of the new cultivar, 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 Petunia.
The photograph at the top of the sheet is a close-up view of typical flowers and leaves of ‘Lanbor’.
The photograph at the bottom of the sheet comprises a side perspective view of a typical plant of ‘Lanbor’ grown in a container.
The aforementioned photographs and following observations and measurements describe plants grown in Bonsall, Calif., in an outdoor nursery during the spring and summer under full sun conditions with day temperatures ranging from about 16 to about 32° C. and night temperatures ranging from about 10 to about 18° C. After planting rooted cuttings, plants were grown for about eight weeks in 12.5-cm containers with three plants per container.
