Abstract

A Bougainvillea plant particularly distinguished by a rounded, low growing, prostrate, and spreading shrub and having rose-colored bracts, is disclosed.

Description

Genus and species: Bougainvillea×spectro-glabra.

Variety denomination: ‘IREBABS2’.

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 ‘IREBABS2’. The new variety originated from an open-pollination between the female Bougainvillea ‘Kayata’ (unpatented) and unknown male Bougainvillea in October 1996. A single plant selection was subsequently chosen in May 1998 for further evaluation and asexual propagation.

The new plant was first asexually propagated October 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.

‘IREBABS2’ has not been made publicly available or sold more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

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, prostrate, and spreading shrub; and
- 2. Having rose-colored bracts.

DESCRIPTION OF THE PHOTOGRAPHS

This new Bougainvillea plant is illustrated by the accompanying photographs which show the overall habit, foliage, reproductive organs and colored bracts of the plant. The colors are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of an approximately ten-year-old plant grown outdoors in Brisbane, Australia.

FIG. 1 shows a close-up the foliage, flower buds, colored bracts, and grey-yellow and grey-purple flowers taken in May 2014.

FIG. 2 shows a close-up a single bract and the reproductive organs taken in May 2014.

FIG. 3 shows the overall plant habit of ‘IREBABS2’ taken in June 2014.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘IREBABS2’. 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 ten-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. 2005).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETY

‘IREBABS2’ differs from the female Bougainvillea parent ‘Kayata’ (unpatented) in that ‘Kayata’ has a taller growing plant habit than ‘IREBABS2’.

‘IREBABS2’ differs from the commercial comparison ‘Kasumi’ (U.S. Plant Pat. No. 22,113) in that ‘IREBABS2’ has rose-colored bracts, while ‘Kasumi’ has salmon-pink bracts.
