Abstract

A new and distinct cultivar of Lobelia plant named ‘Sunlobe Torecama’, characterized by its upright to trailing and mounding plant habit; vigorous growth habit; freely branching habit; dense and bushy plant form; freely flowering habit; long flowering period; large purple violet-colored flowers with white-colored centers; relative tolerance to high temperatures and good garden performance.

Description

Botanical designation: Lobelia erinus.

Cultivar denomination: ‘SUNLOBE TORECAMA’.

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 ‘Sunlobe Torecama’.

The new Lobelia plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new outwardly spreading to trailing Lobelia plants with large attractive flowers, good garden performance and high temperature tolerance.

The new Lobelia plant originated from a cross-pollination made by the Inventor in May, 2012 of a proprietary selection of Lobelia erinus identified as code number 11Lob-16a, not patented, as the female, or seed, parent with a proprietary selection of Lobelia erinus identified as code number 11Lob-16b, 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 Higashiomi, Shiga, Japan in May, 2013.

Asexual reproduction of the Lobelia plant by vegetative cuttings in Higashiomi, Shiga, Japan since May, 2013 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 ‘Sunlobe Torecama’. These characteristics in combination distinguish ‘Sunlobe Torecama’ as a new and distinct Lobelia plant:

- 1. Upright to trailing and mounding plant habit.
- 2. Vigorous growth habit.
- 3. Freely branching habit; dense and bushy plant form.
- 4. Freely flowering habit.
- 5. Long flowering period.
- 6. Large purple violet-colored flowers with white-colored centers.
- 7. Relatively tolerant to high temperatures.
- 8. Good garden performance.

Plants of the new Lobelia differ primarily from plants of the female parent selection in branching habit as plants of the new Lobelia are more freely branching than plants of the female parent selection.

Plants of the new Lobelia differ primarily from plants of the male parent selection in flower size as plants of the new Lobelia have larger flowers than plants of the male parent selection.

Plants of the new Lobelia can be compared to plants of Lobelia erinus ‘Lobmounlila’ , disclosed in U.S. Plant Pat. No. 18,410. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Lobelia differed from plants of ‘Lobmounlila’ in the following characteristics:

- 1. Plants of the new Lobelia were more trailing than and not as upright as plants of ‘Lobmounlila’.
- 2. Plants of the new Lobelia were taller and broader than plants of ‘Lobmounlila’.
- 3. Leaves of plants of the new Lobelia were longer and narrower than leaves of plants of ‘Lobmounlila’.
- 4. Flowers of plants of the new Lobelia had larger centers than flowers of plants of ‘Lobmounlila’.
- 5. Plants of the new Lobelia were more high temperature tolerant than plants of ‘Lobmounlila’.

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 at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunlobe Torecama’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sunlobe Torecama’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown in 15-cm containers during the spring and early summer in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Lobelia production. During the production of the plants, day temperatures averaged 23° C. and night temperatures averaged 13° C. Plants were four months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
