Description

Description

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

Varietal denomination: ‘IBSZ0007’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Iberis, botanically known as Iberis x hybrida, and hereinafter referred to by the variety name ‘IBSZ0007’.

‘IBSZ0007’ is a product of a planned breeding program derived from embryo rescue of a interspecific cross. The new cultivar ‘IBSZ0007’ has very large lavender flowers, grass green foliage, and an upright plant habit.

‘IBSZ0007’ originates from an interspecific cross made by embryo rescue in The Netherlands in 2014. The female parent was an unpatented, proprietary plant designated ‘S0473-52V’ with large lavender flowers flowers, darker green foliage. It belongs to the species I. umbelleta.

The male parent of ‘IBSZ0007’ is an unpatented, proprietary plant designated ‘P1369V’, belonging to the species I. sempervirens. It has large white flowers and a compact habit.

‘IBSZ0007’ was selected as one flowering plant within the progeny of the stated cross in April 2015 in a greenhouse in Enkhuizen, The Netherlands.

The first act of asexual reproduction of ‘IBSZ0007’ was accomplished when vegetative cuttings were propagated from the initial selection in June 2015 in a greenhouse in Enkhuizen, The Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in June 2015 in Enkhuizen, The Netherlands, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘IBSZ0007’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘IBSZ0007’ 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 has been applied for in the European Union on Jun. 25, 2021, No. 2021/1708. ‘IBSZ0007’ 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 ‘IBSZ0007’ 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 Iberis as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawings show typical flower and foliage characteristics of ‘IBSZ0007’ with colors being as true as possible with an illustration of this type.

The photographic drawings show in FIG. 1 a flowering plant of the new variety and

FIG. 2 shows a detailed flower close up.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in Enkhuizen, The Netherlands under natural light in June 2021. These plants were approximately 10 weeks old and were grown in 13 cm pots in outside container field trials. The plants used for the photographs were about 10 weeks old growing in Enkhuizen, The Netherlands and the photographs were taken in June 2021.
