Osteospermum plant named ‘KLEOE22715’

Abstract

A new Osteospermum plant particularly distinguished by pink flowers with white rings and good branching, is disclosed.

Description

Genus and species: Osteospermum ecklonis Norl.

Variety denomination: ‘KLEOE22715’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Osteospermum, botanically known as Osteospermum ecklonis Norl., and hereinafter referred to by the variety name ‘KLEOE22715’. ‘KLEOE22715’ originated from a cross-pollination conducted in Summer through Autumn 2018 in Nairobi, Kenya between the proprietary female Osteospermum variety ‘OE-2017-4277’ (unpatented) and the proprietary male Osteospermum variety ‘OE-2016-3228’ (unpatented).

The seeds from the cross were collected and in winter of 2018 and sown in Stuttgart, Germany and the plants were grown for evaluation. An individual plant designated ‘KLEOE22715’ was selected in May of 2019 in Stuttgart, Germany. In May of 2019 ‘KLEOE22715’ was first vegetatively propagated by vegetative terminal cuttings in Stuttgart, Germany. ‘KLEOE22715’ was found to reproduce true to type in successive generations of asexual propagation via vegetative cuttings.

SUMMARY

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

• • 1. Single, pink flowers with white rings at the center of the flowers; and
  • 2. Good branching.

DESCRIPTION OF THE PHOTOGRAPH

This new Osteospermum plant is illustrated by the accompanying photograph which shows a close-up the foliage, buds, and mature flower. The photograph is of a 12-week-old plant grown outdoors in Stuttgart, Germany in June 2022. 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 ‘KLEOE22715’. The data which define these characteristics were collected in Stuttgart Germany in May 2023 on plants potted in week 8. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^th edition (2007).
