Description

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

Varietal denomination: ‘LOBZ0002’.

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 ‘LOBZ0002’.

‘LOBZ0002’ is a product of a planned breeding program. The new cultivar has large pure white flowers, long inflorescences with good floriferousness, medium green foliage, narrow leaves, freely branching and tight relatively upright plant habit, and relatively strong vigor.

‘LOBZ0002’ originated from a hybridization made in February 2007 in Andijk, Netherlands.

The female parent was the unpatented, proprietary plant designated ‘LOB07-244-2’, having smaller flowers, with shorter and lighter green foliage.

The male parent of ‘LOBZ0002’ was the proprietary, unpatented plant designated ‘LOB07-223-1’, having a less upright plant habit, bigger flowers and thinner stems. The resulting seeds were sown in May 2007.

‘LOBZ0002’ was selected as one flowering plant within the progeny of the stated cross in July 2007 in a controlled environment in Andijk, Netherlands.

The first act of asexual reproduction of ‘LOBZ0002’ was accomplished when vegetative cuttings were propagated from the initial selection in the late summer of 2007 in a controlled environment in Andijk, Netherlands.

BRIEF SUMMARY OF THE INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in the spring of 2008 in Andijk, Netherlands, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘LOBZ0002’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘LOBZ0002’ 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 Dec. 24, 2010, #10-7139. ‘LOBZ0002’ 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.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘LOBZ0002’ with colors being as true as possible with an illustration of this type. The photographic drawing shows a flowering plant of the new variety and a close-up of its flowers.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs were taken in May 2011 of plants grown in a greenhouse trial in Andijk, Netherlands. These plants were grown in 10.5 cm pots and were approximately 14 weeks of age.

The measurements were taken in Andijk, Netherlands in mid May 2011 on 13 week old plants that were growing in 10.5 cm pots in a greenhouse at relatively cool conditions. Plants received 1 terminal pinch of the apices at an early age.
