Description

Latin name of the genus and species of the plant claimed: Calibrachoa spp.

Varietal denomination: ‘Calpriwi’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Calibrachoa, botanically known as Calibrachoa spp., and hereinafter referred to by the variety name ‘Calpriwi’.

‘Calpriwi’ is a product of a planned breeding program. The new cultivar has medium to large sized, white colored flowers, semi-trailing plant habit, medium green foliage, is very early to flower and is more floriferous throughout the season.

‘Calpriwi’ originated from a hybridization made in May 2004 in a controlled breeding environment in Enkhuizen, Netherlands. The female parent was the unpatented proprietary plant designated ‘E0139-1’, with light pink flowers, a more trailing plant habit and is later to flower.

The male parent of ‘Calpriwi’ was an unpatented proprietary plant identified as ‘C4458-1’ with white flowers, a little more upright habit, fewer branches and is less floriferous. The resultant seed was sown in February 2005.

‘Calpriwi’ was selected as one flowering plant within the progeny of the stated cross in May 2005 a controlled environment in Enkhuizen, Netherlands.

The first act of asexual reproduction of ‘Calpriwi’ was accomplished when vegetative cuttings were propagated from the initial selection in May 2005 in a controlled environment in Enkhuizen, Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in May 2005, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Calpriwi’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Calpriwi’ 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.

Plant Breeder's Rights for this cultivar were applied for in Canada on Feb. 9, 2010 (#10-6822) and in CVPO on Sep. 29, 2009 (#2009/1909). ‘Calpriwi’ 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 Calibrachoa as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Calpriwi’ with colors being as true as possible with an illustration of this type.

The photographic drawing shows a flowering potted plant of the new variety and a close-up of the flowers.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs were taken in April 2010 from plants growing in a greenhouse trial in Gilroy, Calif. USA. These plants were growing in 4 inch pots and were approximately 15-16 weeks of age.

The plant descriptions and measurements were taken in mid May 2010 in Hillscheid, Germany on 9 week old plants that were growing in 12 cm pots and were grown without pinching, on benches in a greenhouse at a minimum temperature (heating temperature) of 12° C.

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