Abstract

A new Lavandula plant named ‘LABZ0007’, particularly distinguished by numerous purple sterile large bracts, purple black flowers, medium green foliage without greyish hue, a strong sized plant with a rounded, mounding habit, early to flower and long flowering. The variety is also more winter hardy than normal for the species: minus 5 C is easily survived.

Description

Latin name of the genus and species of the plant claimed: Lavandula stoechas.

Varietal denomination: ‘LABZ0007’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Lavandula, botanically known as Lavandula stoechas, and hereinafter referred to by the variety name ‘LABZ0007’.

‘LABZ0007’ is a product of a planned breeding program. The new cultivar has deep purple flowers and large, violet bracts, medium green foliage with very little greyish hue, small sized plant with a relatively upright plant habit, is early to flower and long flowering.

‘LABZ0007’ originated from a pollination made in 2009 in a greenhouse in Enkhuizen, The Netherlands. The female parent was the unpatented, proprietary plant designated ‘G6114-1’, with a lilac flower, strong habit, and starting to flower 3 weeks later when compared to ‘LABZ0007’.

The male parent of ‘LABZ0007’ is the unpatented, proprietary plant designated ‘N2966-51’ with a purple flower, erect habit that is better winter hardy compared to ‘LABZ0007’.

The resultant seed was sown in January 2011 and grown outdoors in Enkhuizen, The Netherlands. ‘LABZ0007’ was selected as a single flowering plant within the progeny of the stated cross on Jul. 3, 2011 in Enkhuizen, Netherlands.

The first act of asexual reproduction of ‘LABZ0007’ was accomplished when vegetative cuttings were propagated from the initial selection in September 2011 in a greenhouse in Enkhuizen, The Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated September 2011, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘LABZ0007’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘LABZ0007’ 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.

‘LABZ0007’ 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 ‘LABZ0007’ 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 Lavandula as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘LABZ0007’ 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 outdoors in Enkhuizen, The Netherlands on Jul. 14, 2016 on about 13 weeks old plants. Rooted cuttings had been planted into 13 cm pots in week 15 2016. The plants were not pinched.

The aforementioned photograph: FIG. 1 was taken in Enkhuizen, The Netherlands on Jul. 4, 2016 and showing a plant from an outdoor trial. The plant was about 13 weeks of age. Plants started flowering naturally by beginning of August.

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