Abstract

A new and distinct variety of peony plant having red-purple flowers, a perennial herbaceous shrub, having a compact, symmetrically rounded, and vigorous growth habit, is disclosed.

Description

Genus and species: Paeonia lactiflora x Paeonia lutea hybrid.
Denomination: ‘RTPIV 789-03’.
BACKGROUND
‘RTPIV 789-03’ is a new and distinct variety of Paeonia lactiflora x Paeonia lutea hybrid. ‘RTPIV 789-03’ originated from a controlled cross in May 2007 in France between the female parent ‘Miss America’ (unpatented) and the male parent ‘Chinese Dragon’ (unpatented).
The resulting seeds from the cross were collected and planted and evaluated in France. ‘RTPIV 789-03’ was selected in May 2013 from the population of seedlings in France. ‘RTPIV 789-03’ was first asexually propagated in October 2015 in France from vegetative cuttings.
‘RTPIV 789-03’ reproduces true to type in successive generations of asexual reproduction via vegetative cuttings.
SUMMARY
The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in France.
    • 1. Red-purple flowers; and
    • 2. A perennial herbaceous shrub, having a compact, symmetrically rounded, and vigorous growth habit.
DESCRIPTION OF THE PHOTOGRAPHS
This new peony plant is illustrated by the accompanying photographs which show the plant's overall plant habit including form, foliage, and flowers. The photographs are of a six to eight years-old plant grown outdoors in France in May 2019. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.
FIG. 1 shows the overall plant habit and buds, flowers, and foliage of ‘RTPIV 789-03’.
FIG. 2 shows a close-up of an individual open flower.
 DETAILED DESCRIPTION
