Abstract

A new Iberis plant named ‘IBSZ0006’ particularly distinguished by its very large pure white flowers that are early flowering, grass green foliage and a compact, mounded plant habit.

Description

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

Varietal denomination: ‘IBSZ0006’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Iberis, botanically known as Iberis sempervirens, and hereinafter referred to by the variety name ‘IBSZ0006’.

‘IBSZ0006’ is a product of a planned breeding program. The new cultivar ‘IBSZ0006’ has very large pure white flowers that are early flowering, grass green foliage and a compact, mounded plant habit.

‘IBSZ0006’ originates from an open pollination in a greenhouse in April 2010 in Enkhuizen, The Netherlands. The female parent was an unpatented, proprietary plant designated ‘P1252-3’ with medium size white flowers, darker green foliage and is less branched when compared to ‘IBSZ0006’.

The male parent of ‘IBSZ0006’ is unknown. It was a cloud of pollen of all plants available. The resultant seed was sown in August 2010 in Enkhuizen, The Netherlands.

‘IBSZ0006’ was selected as one flowering plant within the progeny of the stated cross in March 2011 in a greenhouse in Enkhuizen, The Netherlands.

The first act of asexual reproduction of ‘IBSZ0006’ was accomplished when vegetative cuttings were propagated from the initial selection in June 2011 in a greenhouse in Enkhuizen, The Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in June 2011 in Enkhuizen, The Netherlands, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘IBSZ0006’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘IBSZ0006’ 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 not been applied for in the European Union on Aug. 1, 2017, No. 2017/1902. ‘IBSZ0006’ has 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 ‘IBSZ0006’ 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 drawing shows typical flower and foliage characteristics of ‘IBSZ0006’ with colors being as true as possible with an illustration of this type.

The photographic drawing shows in FIG. 1 a flowering plant of the new variety.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in Enkhuizen, The Netherlands under natural light in March 2017. These plants were approximately 34 weeks old and were grown in 13 cm pots in hoop-house trials. The plants used for the photographs were about 34 weeks old growing in Enkhuizen, The Netherlands and the photographs were taken in March 2017.
