Abstract: A new and distinct cultivar of Lobelia plant named `Grulo 02`, characterized by its upright, outwardly spreading to cascading plant habit; freely branching habit; early and freely flowering habit; and large white-colored flowers.
Claim: It is claimed:

1. A new and distinct cultivar of Lobelia plant named `Grulo 02`, as illustrated and described.
Description: Botanical designation:Lobelia richardii.

Cultivar denomination: `Grulo 02`.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Lobelia plant, botanically known as Lobelia richardii, and hereinafter referred to by the name `Grulo 02`.

The new Lobelia is a product of a planned breeding program conducted by the Inventor in 's-Gravenzande, The Netherlands. The objective of the breeding program was to develop new Lobelia cultivars with a cascading habit, large flowers andattractive flower colors.

The new Lobelia originated from a cross-pollination made by the Inventor in May, 2002 of a proprietary selection of Lobelia richardii identified as code number IO 3, not patented, as the female, or seed, parent with a proprietary selection ofLobelia richardii identified as code number IO 4, 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 controlledenvironment in 's-Gravenzande, The Netherlands in August, 2002.

Asexual reproduction since September, 2002 of the new cultivar by terminal cuttings in a controlled environment in 's-Gravenzande, The Netherlands, has shown that the unique features of this new Lobelia are stable and reproduced true to type insuccessive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Grulo 02`. These characteristics in combination distinguish `Grulo 02` as a new and distinct cultivar: 1. Upright, outwardly spreading tocascading plant habit. 2. Freely branching habit. 3. Early and freely flowering habit. 4. Large white-colored flowers.

Plants of the new Lobelia and the female parent selection differ primarily in flower color as plants of the female parent selection have light blue-colored flowers. Plants of the new Lobelia and the male parent selection differ primarily inplant form as plants of the male parent selection have a more trailing plant habit.

Plants of the cultivar Grulo 02 can be compared to the cultivar Weslowei, disclosed in U.S. Plant Pat. No. 12,708. However, in side-by-side comparisons conducted in 's-Gravenzande, The Netherlands, plants of the new Lobelia and the cultivarWeslowei differed in the following characteristics: 1. Plants of the new Lobelia were longer than plants of the cultivar Weslowei. 2. Lower flower petals of plants of the new Lobelia were larger than lower flower petals of plants of the cultivarWeslowei. 3. Plants of the new Lobelia flowered about two weeks earlier than plants of the cultivar Weslowei.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

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 slightlyfrom the color values cited in the detailed botanical description, which accurately describe the actual colors of the new Lobelia. The photograph comprises a side view of a typical plant of `Grulo 02` grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Grulo 02 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 ingenotype.

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 aforementioned photograph andfollowing description were grown in an outdoor nursery under conditions that closely approximate commercial production conditions during the spring and summer in 's-Gravenzande, The Netherlands. During the production of the plants, day temperaturesranged from 16.degree. C. to 24.degree. C., night temperatures ranged from 8.degree. C. to 14.degree. C. and light levels ranged from 20,000 to 45,000 lux. Plants were pinched once during the production period. Plants were about four months fromplanting when the photographs and description were taken. Botanical classification: Lobelia richardii cultivar Grulo 02.
