plant named ‘PJ01’

Abstract

A new and distinct Pandorea cultivar named ‘PJ01’ which is characterized by the combination of a compact and freely-branching growth habit, dense foliage, nearly pure white flowers, and the stability of these characteristics from generation to generation.

Description

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Pandorea jasminoides.

Variety denomination: The inventive cultivar of Pandorea disclosed herein has been given the variety denomination ‘PJ01’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Australian Plant Breeders Rights application number 2016/213, filed on Aug. 2, 2016, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘PJ01’ is a seedling selection resulting from the open pollination of a small population of unnamed Pandorea jasminoides plants (not patented) at a commercial plant breeding facility in Clarendon, New South Wales, Australia in 2012. The inventor sowed seed collected from several of these unnamed Pandorea jasminoides plants and grew them to a mature size in order to evaluate for unique characteristics of commercial value. In October of 2013, the inventor observed that one seedling exhibited a smaller plant size with nearly pure white flowers. This seedling was isolated and further evaluated to assess the uniformity and stability of the characteristics first observed. After further evaluation, the claimed plant was selected for commercial production and given the name ‘PJ01’.

Asexual Reproduction: Asexual reproduction of ‘PJ01’, by way of semi-hardwood stem cuttings, was first performed in May of 2014 in Cobbitty, New South Wales, Australia. Through five subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘PJ01’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PJ01’. These characteristics in combination distinguish ‘PJ01’ as a new and distinct Pandorea jasminoides cultivar:

• • 1. Pandorea ‘PJ01’ exhibits a vining, freely branching growth habit with a relatively fast rate of growth; and
  • 2. Pandorea ‘PJ01’ exhibits a relatively compact plant form with shortened internode length and dense foliage, from the base of the plant to the apex.
  • 3. Pandorea ‘PJ01’ exhibits green, glossy foliage; and
  • 4. Pandorea ‘PJ01’ exhibits nearly pure white flowers.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary 3 year old ‘PJ01’, field-grown in Clarendon, New South Wales, Australia. The plant has been removed from the growing container and the soil removed to expose the roots.

FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical mature foliage of ‘PJ01’.

FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical flower of ‘PJ01’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in February of 2017 and, unless otherwise indicated, describe a 3 year old potted ‘PJ01’ field-grown plant produced in a 30 cm container in Clarendon, New South Wales, Australia. Plants were produced under shade, using conventional production protocols for Pandorea which consisted of regular overhead irrigation and controlled-release fertilizer applications. No chemical pest or disease measures were utilized in production.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘PJ01’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2001 edition.
