Description

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

Varietal denomination: ‘LOBZ0018’.

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 ‘LOBZ0018’.

‘LOBZ0018’ is a product of a planned breeding program. The new cultivar has relatively large, light violet flowers, medium green foliage, very good branching and a semi-trailing to trailing plant habit.

The seed from which the variety was grown originates from an open pollination made on the open field in the summer of 2012, The Netherlands.

The female parent was a commercial Lobelia variety ‘Blue Lagoon’ (not patented), with a trialing plant habit, dark blue flower color and less vigorous than ‘LOBZ0018’.

The male parent of ‘LOBZ0018’ is unknown, as the cross from which the variety originates was an open pollination.

The resulting seeds were sown in May 2013, and ‘LOBZ0018’ was selected as one flowering plant within the progeny of the stated cross in September 2013 in a controlled environment in Andijk, The Netherlands.

The first act of asexual reproduction of ‘LOBZ0018’ was accomplished when vegetative cuttings were propagated from, the initial selection in the fall of 2013 in a controlled environment in Andijk, The Netherlands.

BRIEF SUMMARY OF THE INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in the spring of 2014 in Andijk, The Netherlands, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘LOBZ0018’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘LOBZ0018’ 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 has not yet been applied for. ‘LOBZ0018’ has not been made publicly available prior to the effective filing date of this application, notwithstanding any disclosure that may have been made less than one year prior to the effective filing date of this application by the inventor or another who obtained ‘LOBZ0018’ directly from the inventor.

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 photograph drawings show typical flower and foliage characteristics of ‘LOBZ0018’ with colors being as true as possible with an illustration of this type. The drawings show in FIG. 1 a flowering potted plant of the new variety and in FIG. 2 a close-up of its flowers.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs were taken in April 2018 from plants grown in an indoor trial in Andijk, The Netherlands. These plants were grown in containers and were approximately 11 weeks of age. The close-up photograph was taken at the same time.

The measurements were taken in Andijk, The Netherlands in September 2018 on 17 week old plants that were grown outside in containers. Culture of these plants had started in week 21, 2018 with planting of rooted, non-pinched cuttings.
