Lobelia plant named ‘KLELE07247’

Abstract

A new cultivar of Lobelia particularly characterized by light-blue flowers with white eyes, good tolerance to heat and a medium-vigorous growth habit with an upright plant habit and very good branching, is disclosed.

Description

Genus and species: Lobelia erinus.

Variety denomination: ‘KLELE07247’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Lobelia, botanically known as Lobelia erinus, and hereinafter referred to by the cultivar name ‘KLELE07247’. ‘KLELE07247’ originated from an open-pollination made in May 2003 in Stuttgart, Germany between the proprietary female Lobelia plant, ‘040312’ (unpatented) and the male plant, an unnamed individual Lobelia plant (unpatented). A single plant selection was subsequently chosen for further evaluation and for asexual propagation.

The new cultivar was created in 2003 in Stuttgart, Germany and has been asexually reproduced repeatedly by vegetative cuttings and in-vitro propagation in Stuttgart, Germany over a three-year period (about 7 generations). ‘KLELE07247’ has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar were applied for in Switzerland on Jul. 26, 2007. ‘KLELE07247’ has not been made publicly available more than one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal commercial practices in a greenhouse in Stuttgart, Germany.

• • 1. Light-blue flowers with white eyes;
  • 2. Good tolerance to heat; and
  • 3. Medium-vigorous growth habit with an upright plant habit and very good branching.

DESCRIPTION OF THE PHOTOGRAPH

This new Lobelia plant is illustrated by the accompanying photograph which shows a close-up of the mature flowers, buds and foliage; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is of a plant about 3-months old and grown from rooted cuttings in 10-cm pots in a greenhouse (glasshouse) in Stuttgart, Germany in the spring under conditions which approximate those generally used in commercial practice.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘KLELE07247’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. The plant history was taken on 2-month old plants in 10-cm pots that were pinched once and grown in a greenhouse in the spring. The color readings were determined under natural light. Color references are to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘KLELE07247’ differs from the female parent, the proprietary Lobelia ‘040312’ (unpatented) in that ‘KLELE07247’ an upright plant habit, while ‘040312’ has a trailing plant habit. Additionally, ‘KLELE07247’ has a less vigorous growth habit than ‘040312’.

‘KLELE07247’ differs from the commercial comparison variety, ‘Wesloarc’ (U.S. Plant Pat. No. 15,871) in that ‘KLELE07247’ has a better branching habit than ‘Hot Arctic’.
