Calibrachoa plant named ‘CBRZ0013’

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

Varietal denomination: ‘CBRZ0013’.

The present invention comprises a new Calibrachoa , botanically known as Calibrachoa hybrida , and hereinafter referred to by the variety name ‘CBRZ0013’.

‘CBRZ0013’ is a product of a planned breeding program. The new cultivar has mid-sized white flower, green foliage, good branching, late flowering, and a moderately compact, semi-trailing plant habit, and has little sensitivity to soil pH.

‘CBRZ0013’ originated from a hybridization made in March 2010 in a greenhouse in Gilroy, Calif., USA. The female parent was the commercial plant variety ‘Cali White CB298’, ‘G0078-2’. The male parent of ‘CBRZ0013’ was another white flowered plant known as ‘1140-6’.

The resulting seeds were sown in August 2010 and ‘CBRZ0013’ was selected as one flowering plant within the progeny of the stated cross in November 2010 in a controlled environment in Gilroy, Calif.

The first act of asexual reproduction of ‘CBRZ0013’ was accomplished when vegetative cuttings were propagated from the initial selection in the spring of 2011 in a controlled environment in Gilroy, Calif.

Horticultural examination of plants grown from cuttings of the plant initiated in the late spring of 2011, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘CBRZ0013’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘CBRZ0013’ 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 the European Union on Aug. 10, 2017, No. 2017/1997. ‘CBRZ0013’ 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 ‘CBRZ0013’ 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 Calibrachoa as a new and distinct variety.

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘CBRZ0013’ with colors being as true as possible with an illustration of this type.

The photographic drawing shows in FIG. 1 a close-up of the flowers and in FIG. 2 a flowering plant of the new variety.

The aforementioned photographs were taken in April 2017 in Gilroy, Calif.,

The measurements and observations were made in Gilroy, Calif. on plants grown in an indoor trial.
