Abstract

A new and distinct cultivar of Lobelia plant named ‘Wesloarc’, characterized by its upright and mounding plant habit; freely branching habit with short internodes; dense and bushy plant form; continuously and freely flowering habit; densely pubescent stems and leaves; light blue and white bi-colored flowers; and relatively tolerant to high temperatures.

Description

Botanical classification/cultivar designation: Lobelia erinus cultivar Wesloarc.
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 ‘Wesloarc’.
The new Lobelia is a product of a planned breeding program conducted by the Inventor in Südlohn, Germany. The objective of the breeding program was to develop new Lobelia cultivars with continuous flowering, interesting flower colors and high temperature tolerance.
The new Lobelia originated from a cross-pollination made by the Inventor in 2002 of a proprietary selection of Lobelia erinus identified as code number 01P050, not patented, as the female, or seed, parent with a proprietary selection of Lobelia erinus identified as code number 01P508, not patented, as the male, or pollen, parent. The new Lobelia was discovered and selected by the Inventor from within the resultant progeny from the above-mentioned cross-pollination in a controlled environment in Südlohn, Germany in 2002.
Asexual reproduction since 2002 of the new cultivar by terminal cuttings in a controlled environment in Südlohn, Germany, has shown that the unique features of this new Lobelia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Wesloarc’. These characteristics in combination distinguish ‘Wesloarc’ as a new and distinct cultivar:
    • 1. Upright and mounding plant habit.
    • 2. Freely branching habit with short internodes; dense and bushy plant form.
    • 3. Continuously and freely flowering habit.
    • 4. Densely pubescent stems and leaves.
    • 5. Light blue and white bi-colored flowers.
    • 6. Relatively tolerant to high temperatures.
Plants of the new Lobelia have larger flowers than plants of the female parent, a proprietary selection identified as code number 01P050. In addition, plants of the new Lobelia and the female parent selection differ in flower color. Plants of the new Lobelia have foliage with dense pubescence compared to the smooth foliage of plants of the male parent, a proprietary selection identified as code number 01P508. In addition, plants of the new Lobelia have thicker branches than plants of the male parent selection. Flower color of plants of the new Lobelia is lighter blue than flower color of plants of the male parent selection.
Plants of the new Lobelia differ primarily from plants of the cultivar Weslospot, disclosed in U.S. Plant patent application Ser. No. 10/805,581, primarily in flower color.
Plants of the new Lobelia can be compared to plants of the cultivar Weslobigblue, disclosed in U.S. Plant Pat. No. 12,634. However, in side-by-side comparisons conducted in Südlohn, Germany, plants of the new Lobelia differed from plants of the cultivar Weslobigblue in the following characteristics:
    • 1. Plants of the new Lobelia were more upright than plants of the cultivar Weslobigblue.
    • 2. Leaves and stems of plants of the new Lobelia were more pubescent than leaves and stems of plants of the cultivar Weslobigblue.
    • 3. Plants of the new Lobelia had smaller flowers than plants of the cultivar Weslobigblue.
    • 4. Flowers of plants of the new Lobelia were lighter blue in color than flowers of plants of the cultivar Weslobigblue.
Plants of the cultivar Wesloarc can also be compared to the cultivar Weslowei, disclosed in U.S. Pat. No. 12,708. However, in side-by-side comparisons conducted in Südlohn, Germany, plants of the cultivar Wesloarc and the cultivar Weslowei differed in the following characteristics:
    • 1. Plants of the new Lobelia were more upright than plants of the cultivar Weslowei.
    • 2. Leaves and stems of plants of the new Lobelia were more pubescent than leaves and stems of plants of the cultivar Weslowei.
    • 3. Plants of the new Lobelia flowered more continuously than plants of the cultivar Weslowei.
    • 4. Plants of the new Lobelia and the cultivar Weslowei differed in flower color.
    • 5. Plants of the new Lobelia were more tolerant to high temperatures than plants of the cultivar Weslowei.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate 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 photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new Lobelia.
The photograph at the top of the sheet comprises a close-up view of typical individual flowers of ‘Wesloarc’.
The photograph at the bottom of the sheet comprises side view of a typical plant of ‘Wesloarc’ grown in a basket container.
 DETAILED BOTANICAL DESCRIPTION
Plants of the cultivar Wesloarc have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the description were grown in a glass-covered greenhouse and conditions that closely approximate commercial production conditions during the spring and summer in Südlohn, Germany. Plants used for the above-mentioned photographs and following description were grown as one plant per 12-cm container or three plants per 25-cm hanging basket container. During the production of the plants, day temperatures ranged from 20 to 25° C. and night temperatures ranged from 16 to 18° C. Plants were pinched once during the production period by removing about 1 to 2 cm of the uppermost apical growing tip. Plants were about 20 weeks from planting when the photographs and description were taken.
