Abstract

A new Lavandula plant particularly distinguished by early flowering, good branching, and dark-purple bracts, is disclosed.

Description

Genus and species: Lavandula angustifolia.

Variety denomination: ‘KLELV20123’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Lavandula, botanically known as Lavandula angustifolia, and hereinafter referred to by the variety name ‘KLELV20123’. ‘KLELV20123’ originated from a cross-pollination conducted in November 2011 in Cobbitty, New South Wales, Australia between the proprietary female parent ‘LS1009’ (unpatented) and the proprietary male parent ‘LS1012’ (unpatented).

The seeds from the cross were sown and plants were grown outdoors for evaluation, where an individual plant designated ‘KLELV20123’ was selected from the group of plants in September 2012 in Cobbitty, New South Wales, Australia. ‘KLELV20123’ was first vegetatively propagated by stem cuttings in October 2012 in Cobbitty, New South Wales, Australia. ‘KLELV20123’ was found to reproduce true to type in successive generations of asexual propagation via vegetative stem cuttings.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Stuttgart, Germany.

- 1. Early flowering;
- 2. Good branching; and
- 3. Dark-purple bracts.

DESCRIPTION OF THE PHOTOGRAPH

This new Lavandula plant is illustrated by the accompanying photograph which shows the plant's overall plant habit including form, foliage, and flowers. The photograph is of a 14-week-old plant grown in a greenhouse in Stuttgart, Germany in August 2020. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘KLELV20123’. The data which define these characteristics were collected from asexual reproductions carried out in Cobbitty, New South Wales, Australia in November 2019. Data was collected on four-month-old plants grown outdoors. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^thedition (2007).
