Genus and species: Lavandula angustifolia.
Variety denomination: ‘KLELV16122’.
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 ‘KLELV16122’. ‘KLELV16122’ originated from a cross-pollination conducted in June 2010 in Cobbitty, New South Wales, Australia between the proprietary female parent ‘LA10.10.01’ (unpatented) and the proprietary male parent ‘LA10.20.02’ (unpatented).
The seeds from the cross were sown and plants were grown outdoors for evaluation, where an individual plant designated ‘KLELV16122’ was selected from the group of plants in May 2012 in Cobbitty, New South Wales, Australia. In May 2012 in Cobbitty, New South Wales, Australia. ‘KLELV16122’ was first vegetatively propagated by stem cuttings. ‘KLELV16122’ was found to reproduce true to type in successive generations of asexual propagation via 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. Long spikes.
CROSS-REFERENCE TO RELATED APPLICATIONS
An application with the Community Plant Variety Rights Office was filed on Jun. 21, 2017. ‘KLELV16122’ has not been made publicly available or sold more than one year prior to the filing date of the instant application.
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 12-week-old plant grown in a greenhouse in Stuttgart, Germany in August 2015. 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 ‘KLELV16122’. The data which define these characteristics were collected from asexual reproductions carried out in Cobbitty, New South Wales, Australia in October 2016. Data was collected on four-month-old plants grown in a greenhouse. Color references are to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5th edition (2007).
