Abstract

A new and distinct cultivar of Lobelia plant named ‘WNLOLASKBL’, characterized by its upright to outwardly spreading and mounding to trailing plant habit; vigorous growth habit; freely branching habit; dense and bushy plant form; freely flowering habit; long flowering period; purplish blue-colored flowers; and relative high temperature tolerance and good garden performance.

Description

Botanical designation: Lobelia erinus.
Cultivar denomination: ‘WNLOLASKBL’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Lobelia plant, botanically known as Lobelia erinus and hereinafter referred to by the name ‘WNLOLASKBL’.
The new Lobelia plant is a product of a planned breeding program conducted by the Inventor in Alajuela, Costa Rica and Carleton, Mich. The objective of the breeding program is to create new outwardly spreading, freely-branching and bushy Lobelia plants with a long flowering period, high temperature tolerance and good garden performance.
The new Lobelia plant originated from a cross-pollination made by the Inventor in Alajuela, Costa Rica in November, 2016 of Lobelia erinus ‘Lobtrawi’, disclosed in U.S. Plant Pat. No. 18,216, as the female, or seed, parent with Lobelia erinus ‘Weslosnowhi’, not patented, as the male, or pollen, parent. The new Lobelia plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Carleton, Mich. on Nov. 1, 2017.
Asexual reproduction of the Lobelia plant by vegetative terminal cuttings in Carleton, Mich. since Nov. 15, 2017 has shown that the unique features of this new Lobelia plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Lobelia 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 ‘WNLOLASKBL’. These characteristics in combination distinguish ‘WNLOLASKBL’ as a new and distinct Lobelia plant:
    • 1. Upright to outwardly spreading and mounding to trailing plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit; dense and bushy plant form.
    • 4. Freely flowering habit.
    • 5. Long flowering period.
    • 6. Purplish blue-colored flowers.
    • 7. Relative high temperature tolerance and good garden performance.
Plants of the new Lobelia differ primarily from plants of the female, parent, ‘Lobtrawi’, in the following characteristics:
    • 1. Plants of the new Lobelia are more high temperature tolerant than plants of ‘Lobtrawi’.
    • 2. Plants of the new Lobelia and ‘Lobtrawi’ differ in flower color as plants of the new Lobelia have purplish blue-colored flowers whereas plants of ‘Lobtrawi’ have white-colored flowers.
Plants of the new Lobelia differ primarily from plants of the male, parent, ‘Weslosnowhi’, in the following characteristics:
    • 1. Plants of the new Lobelia are more vigorous than and not as compact as plants of ‘Weslosnowhi’.
    • 2. Plants of the new Lobelia and ‘Weslosnowhi’ differ in flower color as plants of the new Lobelia have purplish blue-colored flowers whereas plants of ‘Weslosnowhi’ have white-colored flowers.
Plants of the new Lobelia can be compared to plants of Lobelia erinus ‘Loboudtis’, disclosed in U.S. Plant Pat. No. 15,526. In side-by-side comparisons, plants of the new Lobelia differ primarily from plants of ‘Loboudtis’ in the following characteristics:
    • 1. Plants of the new Lobelia are more freely flowering than plants of ‘Loboudtis’.
    • 2. Plants of the new Lobelia have larger flowers than plants of ‘Loboudtis’.
    • 3. Plants of the new Lobelia flower more freely and for a longer period of time under high temperature conditions than plants of ‘Loboudtis’.
Plants of the new Lobelia can also be compared to plants of Lobelia erinus ‘Tech Helitbule’, disclosed in U.S. Plant Pat. No. 19,067. In side-by-side comparisons, plants of the new Lobelia differ primarily from plants of ‘Tech Helitbule’ in the following characteristics:
    • 1. Plants of the new Lobelia are more trailing than plants of ‘Tech Helitbule’.
    • 2. Plants of the new Lobelia have larger flowers than plants of ‘Tech Helitbule’.
    • 3. Plants of the new Lobelia flower more freely under high temperature conditions than plants of ‘Tech Helitbule’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Lobelia 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 actual colors of the new Lobelia plant.
The photograph on the first sheet (FIG. 1 of 2) comprises a side perspective view of a typical flowering plant of ‘WNLOLASKBL’ grown in a container.
The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical flowering plant of ‘WNLOLASKBL’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the autumn and winter in 10.8-cm containers in a glass-covered greenhouse in Loudon N.H. and under cultural practices typical of commercial Lobelia production. During the production of the plants, day and night temperatures averaged 19° C. Plants were pinched three weeks after planting and were nine weeks from planting rooted cuttings when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
