Osteospermum plant named ‘KLEOE16287’

Abstract

A new Osteospermum plant particularly distinguished by white flowers and a spreading growth habit, is disclosed.

Description

Genus and species: Osteospermum ecklonis.

Variety denomination: ‘KLEOE16287’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Osteospermum, botanically known as Osteospermum ecklonis, and hereinafter referred to by the variety name ‘KLEOE16287’. ‘KLEOE16287’ originated from a cross-pollination conducted in the time of May to October, 2011 in Nairobi, Kenya between the proprietary female Osteospermum variety ‘KLEOE14215’ (U.S. Plant Pat. No. 26,694), and the proprietary male Osteospermum variety ‘OE-2002-V 068’ (unpatented).

The seeds from the cross were sown and plants were grown in a greenhouse for evaluation, where an individual plant designated ‘KLEOE16287’ was selected from the group of plants in May 2012 in Stuttgart, Germany. In September 2013 in Stuttgart, Germany, ‘KLEOE16287’ was first vegetatively propagated by vegetative terminal cuttings. ‘KLEOE16287’ was found to reproduce true to type in successive generations of asexual propagation via vegetative terminal 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. White flowers; and
  • 2. A spreading habit.

DESCRIPTION OF THE PHOTOGRAPH

This new Osteospermum plant is illustrated by the accompanying photograph which shows the plant's overall plant habit including form, foliage, and flowers. The photograph is of an 8-week-old plant grown in a greenhouse in Stuttgart, Germany in April 2015. 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 ‘KLEOE16287’. The data which define these characteristics were collected from asexual reproductions carried out in Latina, Italy in April 2017. Data was collected on six-month-old plant grown outdoors in March 2017. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^th edition (2007).
