Abstract

A new Dahlia plant named ‘DAHZ0014’, particularly distinguished by scarlet-rose bi-color double flowers, compact and upright plant habit with good branching, medium green foliage, and good floriferousness.

Description

Latin name of the genus and species of the plant claimed: Dahlia hybrid Cav.

Varietal denomination: ‘DAHZ0014’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Dahlia, botanically known as Dahlia hybrid and hereinafter referred to by the variety name ‘DAHZ0014’.

‘DAHZ0014’ is a product of a planned breeding program. The new cultivar has scarlet rose bi-color double flowers, compact and upright plant habit with good branching, medium green foliage, and good floriferousness.

‘DAHZ0014’ originates from a sibling cross hybridization in a controlled breeding program in Andijk, Netherlands. The pollinations were made Andijk, Netherlands in May 2008.

The female parent was an unpatented, proprietary hybrid seedling identified as ‘D08-69-16’, having red-rose bi-color flower color, dark green foliage and a more compact plant habit than ‘DAHZ0014’.

The male parent of ‘DAHZ0014’ was an unpatented, proprietary plant identified as ‘D07-310’ with bronze-white bi-color flower color, medium flower size, light green leaves, and not good branching plant habit.

The resulting the seed sown in May 2009, and ‘DAHZ0014’ was selected as one flowering plant within the progeny of the stated cross in September 2009 in a greenhouse in Andijk, Netherlands.

The first act of asexual reproduction of ‘DAHZ0014’ was accomplished when vegetative cuttings were propagated from the initial selection in October 2009 in a controlled environment in Andijk, Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in April 2012 in Andijk, Netherlands, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘DAHZ0014’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘DAHZ0014’ 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 Community Plant Variety Office (CPVO) on May 5, 2014, No. 2014/1210. ‘DAHZ0014’ 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 Dahlia as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawings show typical flower and foliage characteristics of ‘DAHZ0014’ with colors being as true as possible with an illustration of this type. The photographic drawings show in FIG. 1, a close-up of the flowers and in FIG. 2, a flowering potted plant of the new variety.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs were taken in May 2013 in Andijk, Netherlands. The plants were growing in 13 cm pots on benches in a greenhouse. They were about 14 weeks of age

The plant descriptions and measurements were taken in Enkhuizen, The Netherlands on Sep. 4, 2014, from 14 week old plants that were growing outdoors in the trial field.

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