plant named ‘KLESG14831’

Abstract

A new sutera plant particularly distinguished by having large blue flowers is disclosed.

Description

Genus and species: Sutera grandiflora.

Variety denomination: ‘KLESG14831’.

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 ‘KLESG14831’. ‘KLESG14831’ originated from a controlled cross between the proprietary female sutera variety ‘SG-2009-0077’ (unpatented) and proprietary male sutera variety ‘SG-1985-Scopia GVM’ (unpatented).

In August of 2010, the two sutera parental lines, ‘SG-2009-0077’ and ‘SG-1985-Scopia GVM’ were crossed in Nairobi, Kenya, and seeds were obtained. The seeds were sown and plants were grown for evaluation in Stuttgart, Germany. A plant line was selected in May 2011, which had a blue flower color and subsequently named ‘KLESG14831’. In May 2011, ‘KLESG14831’ was first vegetatively propagated by vegetative cuttings in Stuttgart, Germany. ‘KLESG14831’ was found to reproduce true to type in successive generations of asexual propagation via vegetative cuttings and in-vitro propagation in Stuttgart, Germany.

SUMMARY

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

• • 1. Blue flower color; and
  • 2. Large flowers.

DESCRIPTION OF THE PHOTOGRAPH

This new sutera plant is illustrated by the accompanying photograph which shows the flowers and foliage of the plant. The photograph is of a three-month-old plant grown in a controlled greenhouse environment in Stuttgart, Germany in May 2014.

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 ‘KLESG14831’. The data which define these characteristics were collected from asexual reproductions by in-vitro cultivation carried out in Stuttgart, Germany. Data was collected on 13-week-old plants grown in a controlled greenhouse environment in Stuttgart, Germany in June 2015. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), (2005).
