Abstract

A new Aubrieta plant named ‘Aubnere’ particularly distinguished by the large, vibrant purple-violet flower color, compact and mounded plant habit that is early flowering, and has a longer flowering period.

Description

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

Varietal denomination: ‘Aubnere’.

BACKGROUND OF THE NEW PLANT

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

‘Aubnere’ is a product of a planned breeding program. The new cultivar has large, vibrant purple-violet flower color, compact and mounded plant habit that is early flowering, and has a longer flowering period.

‘Aubnere’ originated from a sibling cross made in April 2004 in a controlled breeding environment in Enkhuizen, Netherlands. The female parent was the proprietary plant designated ‘G1258-52’, unpatented, with red flowers. ‘G1258-52’ is later to flower and has smaller flowers than ‘Aubnere’.

The male parent of ‘Aubnere’ was an unpatented plant identified as ‘G1258-51’ with violet flowers. ‘G1258-51’ is earlier to flower and has smaller flowers than ‘Aubnere’.

The seed was sown in September 2004 and ‘Aubnere’ was selected as one flowering plant within the progeny of the stated cross in March 2005 in a controlled environment in Enkhuizen, Netherlands.

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

BRIEF SUMMARY OF INVENTION

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

‘Aubnere’ 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.

No Plant Breeder's Rights for this cultivar have been applied for. ‘Aubnere’ 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 PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Aubnere’ 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 plant descriptions, measurements and aforementioned photographs were taken in Gilroy, Calif. USA, in a greenhouse under natural light in February 2010. These plants used for the photographs and descriptions were about 5 months old, and were grown in an outdoor hoop house.

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