plant named ‘IREBABS6’

Abstract

A Bougainvillea plant particularly distinguished by a rounded, low growing, and spreading shrub, prolific flowering, purple-violet bracts, and variegated foliage, is disclosed.

Description

Genus and species: Bougainvillea×spectro-glabra.

Variety denomination: ‘IREBABS6’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Bougainvillea, botanically known as Bougainvillea×spectro-glabra, and hereinafter referred to by the variety name ‘IREBABS6’. The new variety originated from a branch mutation of the Bougainvillea parent ‘Nonya’ (unpatented) in October 1997.

The new plant was first asexually propagated May 1998 in Brisbane, Australia and has been asexually reproduced by cuttings for numerous generations in Brisbane, Australia. The present invention has been found to retain its distinctive characteristics through successive asexual propagations by cuttings.

‘IREBABS6’ has not been made publicly available or sold more than one year prior to the filing of this application.

SUMMARY

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

• • 1. A rounded, low growing, and spreading shrub; and
  • 2. Having prolific flowering, purple-violet bracts and variegated foliage.

DESCRIPTION OF THE PHOTOGRAPHS

This new Bougainvillea plant is illustrated by the accompanying photographs which show the foliage and colored bracts of the plant. The colors are as true as can be reasonably obtained by conventional photographic procedures of plants grown outdoors in Brisbane, Australia.

FIG. 1 shows a close-up of the variegated foliage a plant approximately less than one-year-old.

FIG. 2 shows a close-up of the variegated foliage and bracts of a plant approximately six-years-old.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘IREBABS6’. The data which defines these characteristics were collected from asexual reproductions carried out in Brisbane, Australia. The plant history was taken in May 2013 on five-year-old plants grown outdoors in Brisbane, Australia. Color references were taken under natural light and are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S. 2001).
