ABSTRACT:
Botanical classification/cultivar designation:
Lobelia erinus
cultivar Weslolav.
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 ‘Weslolav’.
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 the
Lobelia erinus
cultivar Weslobigblue, disclosed in U.S. Plant Pat. No. 12,634, 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 ‘Weslolav’. These characteristics in combination distinguish ‘Weslolav’ as a new and distinct cultivar:
1. Cascading plant habit.
2. Freely branching habit with short internodes; bushy and dense plant form.
3. Continuously and freely flowering habit.
4. Densely pubescent stems and leaves.
5. Light lavender-colored flowers.
6. Relatively tolerant to high temperatures.
Plants of the new
Lobelia
have larger flowers than 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, the cultivar Weslobigblue. In addition, plants of the new
Lobelia
have thicker stems than plants of the cultivar Weslobigblue and differ in flower color.
Plants of the new
Lobelia
differ primarily from plants of the cultivar Weslowhite, disclosed in U.S. Plant patent application Ser. No. 10/805,583 primarily in flower color.
Plants of the cultivar Weslolav can be compared to the cultivar Weslowei, disclosed in U.S. Plant Pat. No. 12,708. However, in side-by-side comparisons conducted in Südlohn, Germany, plants of the cultivar Weslolav and the cultivar Weslowei differed in the following characteristics:
1. Plants of the new
Lobelia
had thinner stems than plants of the cultivar Weslowei.
2. Plants of the new
Lobelia
had foliage and stems were more pubescent than 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 coloration.
5. Plants of the new
Lobelia
were more tolerant to high temperatures than plants of the cultivar Weslowei.
