LAVANDULA PLANT NAMED 'LAAZ0014'

Abstract

A new Lavandula plant named ‘LAAZ0014’ particularly distinguished by dark purple-blue flowers, a very long flower spikes, dark green foliage, very abundant flowering, large sized plants with a well-branched, relatively tight and upright habit.

Description

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

Varietal denomination: ‘LAAZ0014’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Lavandula, botanically known as Lavandula angustifolia, and hereinafter referred to by the variety name ‘LAAZ0014’.

‘LAAZ0014’ is a product of a planned breeding program. The new cultivar has purple-blue flowers, a very long flowering season, dark green foliage, very abundant flowering, relative large spikes, relatively tight and upright habit. The plant is tolerant to cold, but main use will be for summer production.

‘LAAZ0014’ originated from a pollination made in July 2019 in a greenhouse in Enkhuizen, The Netherlands.

The female parent was the unpatented, proprietary plant designated ‘LAVAY2354-5’, with blue violet flowers, small spikes, greyish foliage and abundant flowering compared to ‘LAAZ0014’.

The male parent of ‘LAAZ0014’ was the unpatented, proprietary plant designated ‘LAVAY2265-17’, with blue violet flowers, large spikes, green foliage and a tight and narrow habit compared to ‘LAAZ0014’.

The resultant seed was sown in January 2020 and grown outdoors in Enkhuizen, The Netherlands. ‘LAAZ0014’ was selected as a single flowering plant within the progeny of the stated cross in June 2020 in Enkhuizen, The Netherlands.

The first act of asexual reproduction of ‘LAAZ0014’ was accomplished when vegetative stem cuttings were propagated from the initial selection July 2020 in a greenhouse in Enkhuizen, The Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in July 2020, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘LAAZ0014’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘LAAZ0014’ 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 Nov. 16, 2023, No. 2023/2395. ‘LAAZ0014’ 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 ‘LAAZ0014’ 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 drawings show typical flower and foliage characteristics of ‘LAAZ0014’ with colors being as true as possible with an illustration of this type.

The photographic drawings show in FIG. 1 a close view of an inflorescence and in

FIG. 2 a whole flowering plant from an outdoor trial.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken outdoors in Enkhuizen, The Netherlands on Jul. 25, 2024 on about 21 week old plants. Rooted cuttings had been planted, one plant per pot, in 13 cm pots in week 10, 2024. The plants were pinched.

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