plant named ‘KLEVP15483’

Abstract

A new verbena plant particularly distinguished by blue violet flowers, early flowering, and good tolerance to powdery mildew, disclosed.

Description

Genus and species: Verbena sp.

Variety denomination: ‘KLEVP15483’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of verbena, botanically known as Verbena sp., and hereinafter referred to by the variety name ‘KLEVP15483’. ‘KLEVP15483’ originated from a cross-pollination conducted in September 2010 in Cobbitty, New South Wales, Australia between the proprietary female verbena variety ‘VC11ABV’ (unpatented), and the proprietary male verbena variety ‘VC11126’ (unpatented).

The seeds from the cross were sown and plants were grown for evaluation, where an individual plant designated ‘KLEVP15483’ was selected from the group of plants in Cobbitty, New South Wales, Australia in April 2011.

In April 2011, ‘KLEVP15483’ was first vegetatively propagated by vegetative cuttings in Cobbitty, NSW, Australia. ‘KLEVP15483’ 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 Cobbitty, New South Wales, Australia.

• • 1. Blue violet flowers;
  • 2. Early flowering; and
  • 3. Good tolerance to powdery mildew.

DESCRIPTION OF THE PHOTOGRAPH

This new verbena plant is illustrated by the accompanying photograph which shows a close up of the plant's foliage and flowers. The photograph is of a 14-week-old plant grown in a greenhouse in Stuttgart, Germany in May, 2013.

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 ‘KLEVP15483’. The data which define these characteristics were collected from asexual reproductions carried out in Cobbitty, New South Wales, Australia. Data was collected on three-month-old plants grown in a greenhouse in Cobbitty, New South Wales, Australia in June 2015 in Cobbitty, New South Wales, Australia. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^th edition (2007) except where noted.
