Description

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

Varietal denomination: ‘Tec Hewhitt’.

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 ‘Tec Hewhitt.’

‘Tec Hewhitt’ is a product of a planned breeding program. The new cultivar has large pure white flowers, medium green foliage, vigorous and well branched habit, and early flowering.

‘Tec Hewhitt’ originated from a hybridization made in July 2006 in a controlled breeding environment in Andijk, Netherlands. The seed was sown in September 2006. The female parent was the unpatented, proprietary plant designated ‘LOB03-116-1,’ with smaller white flowers, lighter foliage and shorter stems.

The male parent of ‘Tec Hewhitt’ was an unpatented, proprietary plant designated as ‘LOB02-21-1’ with white flowers. ‘LOB02-21-1’ has smaller foliage, longer internodes, thinker stems, and a less trailing habit than ‘Tec Hewhitt.’

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

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

BRIEF SUMMARY OF INVENTION

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

‘Tec Hewhitt’ 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 Jan. 30, 2009. ‘Tec Hewhitt’ 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 drawing shows typical flower and foliage characteristics of ‘Tec Hewhitt’ with colors being as true as possible with an illustration of this type.

The photographic drawing shows in FIG. 1 three flowering potted plants of the new variety, and in

FIG. 2 a close-up of the flowers.

 DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in Hillscheid, Germany in April 2009. These plants were approximately 11 weeks old and were growing in 12 cm pots, in greenhouse trials. The plants used for the photographs were about 12-14 weeks old and growing in Gilroy, Calif.; three plants in a 10 inch basket.

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