Abstract: A new and distinct Lobelia cultivar named `DANANB6` is disclosed, characterized by having bright blue flowers flowers, trailing plant habit, highly floriferous flowering and neutral flowering habit. The new variety is a Lobelia, normally produced as an outdoor garden or container plant.
Claim: What is claimed is:

1. A new and distinct cultivar of Lobelia plant named `DANANB6` as herein illustrated and described.
Description: Latin nameof the genus and species: Lobelia erinus.

Variety denomination: `DANANB6`.

BACKGROUND OF THE INVENTION

The new Lobelia cultivar is a product of a planned breeding program conducted by the inventor, Gabriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new trailing perennial Lobelia varieties. The seed parent is the unpatented, proprietary seedling variety referred to as Lobelia erinus `LOB-6-382.` The pollen parent is the unpatented, proprietary seedling variety referred to as Lobelia erinus `LOB-6-241.` The new variety was discovered inApril 2005 by the inventor in a group of seedlings resulting from that crossing, in a commercial greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar `DANANB6` by vegetative cuttings was first performed at a commercial greenhouse in Moshav Mishmar Hashiva, Israel in April 2005. Subsequent propagation has shown that the unique features of this cultivarare stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar `DANANB6` has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance ingenotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `DANANB6` These characteristics in combination distinguish `DANANB6` as a new and distinct Lobelia cultivar: 1. Trailing plant habit. 2. Large flowers. 3. Flat flower, whereas most Lobelias have undulating flowers.

Plants of the new cultivar `DANANB6` are similar to plants of the parent, Lobelia erinus `LOB-6-382` in most horticultural characteristics, however, plants of the new cultivar `DANANB6` are trailing, compared to an erect habit of the femaleparent. Additionally, plants of the new variety have glossy green leaves, compared to matte leaves of the female parent, and flowers of the new variety are blue with a white eye, compared to all blue of the female parent.

Plants of the new cultivar `DANANB6` are similar to plants of the parent, Lobelia erinus `LOB-6-241` in most horticultural characteristics, however, plants of the new cultivar `DANANB6` are trailing, compared to the mounded habit of the pollenparent. Additionally, plants of the new variety have a lighter blue flower than the male parent.

COMMERCIAL COMPARISON

Plants of the new cultivar `DANANB6` are best compared to the commercial variety `WESLOSPOT,` U.S. Plant Pat. No. 15,835. The new variety `DANANB6` is similar to `WESLOSPOT` in most horticultural characteristics, however, `DANANB6` plants havea trailing habit compared to the erect habit of `WESLOSPOT.` Additionally, plants of `DANANB6` have thinner, more flexible branches, and much glossier leaves than plants of `WESLOSPOT.`

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of `DANANB6` grown in a greenhouse, in a 12 cm pot. Age of the plant photographed is approximately 90 days from a rooted cutting.

FIG. 2 illustrates in full color a close up of a typical bloom of `DANANB6.`

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
