Abstract

A new Osteospermum plant named ‘Tra Whit,’ particularly distinguished by the medium to large white ray florets, early flowering habit, compact and upright plant habit with green leaves and excellent branching.

Description

Latin name of the genus and species of the plant claimed: Osteospermum ecklonis.

Varietal denomination: ‘Tra Whit’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Osteospermum, botanically known as Osteospermum ecklonis, and hereinafter referred to by the variety name ‘Tra Whit.’

‘Tra Whit’ is a product of a planned breeding program. The new cultivar has medium to large white ray florets, early flowering habit, compact and upright plant habit with green leaves and excellent branching.

‘Tra Whit’ 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 proprietary plant designated ‘O03-20-2,’ unpatented, with light purple flower color. ‘O03-20-2’ has less vigorousness and smaller flowers than ‘Tra Whit.’

The male parent of ‘Tra Whit’ was a proprietary plant designated as ‘O03-6-1,’ unpatented, with white and blue eyed flowers. ‘O03-6-1’ has smaller flowers and less vigor than ‘Tra Whit.’

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

The first act of asexual reproduction of ‘Tra Whit’ was accomplished when terminal 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 the cuttings of the plant initiated in January 2007, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Tra Whit’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Tra Whit’ 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. ‘Tra Whit’ 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 Osteospermum as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photographic drawings show in FIG. 1, a flowering plant of the new variety growing in a outdoor field trial in Gilroy, Calif. in the summer of 2009, and in

FIG. 2, a close-up of the flowers.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in Salinas, Calif. in the summer of 2009 under natural light. These plants were started and grown in Gilroy, Calif., and then planted into the outdoor garden in Salinas. Plants were approximately 8-9 months old.

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