plant named ‘KLESG15004’

Abstract

A new Sutera plant particularly distinguished by having large flowers with a light blue flower color, good quality and very good branching, is disclosed.

Description

Genus and species: Sutera grandiflora.

Variety denomination: ‘KLESG15004’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Sutera, botanically known as Sutera grandiflora, and hereinafter referred to by the variety name ‘KLESG15004’. ‘KLESG15004’ originated from an open-pollination in the summer of 2011 in Stuttgart, Germany, between the proprietary female Sutera variety ‘SG-2011-0073’ (unpatented) and an unknown male Sutera variety.

In August of 2011, seed was collected from the open-pollination cross of two Sutera parental lines, ‘SG-2011-0073’ and an unknown Sutera in Stuttgart, Germany. The seeds were sown in February 2012 and plants were grown for evaluation. A plant line was selected in May 2012 and subsequently named ‘KLESG15004’. In May 2012, ‘KLESG15004’ was first vegetatively propagated by in-vitro cultivation in Stuttgart, Germany and in Italy. ‘KLESG15004’ was found to reproduce true to type in successive generations of asexual propagation via in-vitro cultivation.

SUMMARY

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

• • 1. Large flowers with a light blue flower color;
  • 2. Good flower quality; and
  • 3. Very good branching.

DESCRIPTION OF THE PHOTOGRAPH

This new Sutera plant is illustrated by the accompanying photograph, which shows an overall view of the plant. The photograph is of a 13-week-old plant grown in Stuttgart, Germany in July of 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 ‘KLESG15004’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. Data was collected on 10-week-old plants after potting, grown in a controlled greenhouse environment in Stuttgart, Germany in June of 2016. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^th edition (2005).
