Abstract

A new Lobelia plant named ‘LOBZ0004’ particularly distinguished by the large light blue and white bi-color flowers, medium green foliage, and a vigorous well branched, upright and mounded plant habit.

Description

Latin name of the genus and species of the plant claimed: Lobelia erinus.

Varietal denomination: ‘LOBZ0004’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Lobelia, botanically known as Lobelia erinus, and hereinafter referred to by the variety name ‘LOBZ0004’.

‘LOBZ0004’ is a product of a planned breeding program. The new cultivar has large violet-blue flowers, medium green foliage, and a vigorous well branched, upright, and mounded plant habit.

‘LOBZ0004’ originated from a hybridization made in January 2007 in Andijk, The Netherlands. The female parent was the unpatented, proprietary plant designated ‘LOB06-235-2’ with larger blue with a white eye flower color, and longer, darker green foliage than that of ‘LOBZ0004’.

The male parent of ‘LOBZ0004’ was an unpatented, proprietary plant designated ‘LOB03-117-1’ with a smaller flower size and a white flower color, with shorter stems than that of ‘LOBZ0004’. The seeds were sown in May 2007.

‘LOBZ0004’ was selected as one flowering plant within the progeny of the stated cross in May 2007 in a greenhouse in Andijk, The Netherlands.

The first act of asexual reproduction of ‘LOBZ0004’ was accomplished when vegetative cuttings were propagated from the initial selection in May 2007 in a greenhouse in Andijk, The Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in May 2007, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘LOBZ0004’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘LOBZ0004’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and day length.

A Plant Breeder's Right for this cultivar was applied for in Canada on Nov. 1, 2011, No. 11-7428. ‘LOBZ0004’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Lobelia as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawings show typical flower and foliage characteristics of ‘LOBZ0004’ with colors being as true as possible with an illustration of this type.

The photographic drawings show in FIG. 1 a close-up of the flower and in FIG. 2 a flowering plant of the new variety.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in Gilroy, Calif. under natural light in May 2012. These plants were approximately 22-23 weeks old and were growing 5 plants in a 10 inch pot in greenhouse trials. The plants used for the photographs were about 14 weeks old, growing in a greenhouse trial in 10 cm pots, in Enkhuizen, The Netherlands. The photographs were taken in April 2012.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
