plant named ‘ABRZ0007’

Abstract

A new Aubrieta plant named ‘ABRZ0007’ particularly distinguished by its very deep purple flowers, a compact and mounding habit with strong vigor, and a good winterhardiness.

Description

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

Varietal denomination: ‘ABRZ0007’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Aubrieta, botanically known as Aubrieta hybrida and hereinafter referred to by the variety name ‘ABRZ0007’.

‘ABRZ0007’ is a product of a planned breeding program. The new cultivar ‘ABRZ0007’ has deep purple flowers, a compact and mounding habit with strong vigor and is very winter hardy.

‘ABRZ0007’ originates from a hybridization in a controlled breeding program in a greenhouse in Enkhuizen, The Netherlands. The female parent was an unpatented, proprietary plant identified as ‘H2669-52’ with purple flowers and less branching compared to ‘ABRZ0007’.

The male parent of ‘ABRZ0007’ was an unpatented, proprietary plant identified as ‘G1509-52’ with deep purple flower color with an eye and larger leaves compared to ‘ABRZ0007’. The resultant seed was sown in August 2009 in a greenhouse in Enkhuizen, The Netherlands.

‘ABRZ0007’ was selected as one flowering plant within the progeny of the stated cross in March 2010 in a greenhouse in Enkhuizen, The Netherlands.

The first act of asexual reproduction of ‘ABRZ0007’was accomplished when vegetative cuttings were propagated from the initial selection in May 2010 in a greenhouse in Enkhuizen, The Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in May 2010 in Enkhuizen, The Netherlands, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘ABRZ0007’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘ABRZ0007’ 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 May 27, 2015 and assigned No. 2015/1080. ‘ABRZ0007’ 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 Aubrieta as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘ABRZ0007’ 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.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in Enkhuizen, The Netherlands under natural light in March 2015. These plants were approximately 22 weeks old and were growing in 13 cm pots, in shade-house trials.

The plants used for the photographs were about 22 weeks old grown in Enkhuizen, The Netherlands and taken in March 2015.
