Cherry laurel plant named ‘Zsófi’

Abstract

A new cherry laurel plant particularly distinguished by having a broad upright to spreading habit, a broad obovate plant shape, and a moderate growth rate, is disclosed.

Description

Genus and species: Prunus laurocerasus.

Variety denomination: ‘Zsófi’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of cherry laurel plant, botanically known as Prunus laurocerasus, and hereinafter referred to by the variety name ‘Zsófi’. ‘Zsófi’ originated from an open-pollination conducted in Szombathely, Hungary in May 2009 between un-named and unpatented Prunus laurocerasus parent plants.

The seeds from the open-pollination were sown and plants were grown outdoors for evaluation, where an individual plant designated ‘Zsófi’ was selected from the group of plants in Szombathely, Hungary in May 2011. In October 2017, ‘Zsófi’ was first vegetatively propagated by softwood cuttings. ‘Zsófi’ was found to reproduce true to type in successive generations of asexual propagation via softwood cuttings.

SUMMARY

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

• • 1. A broad upright to spreading habit;
  • 2. A broad obovate plant shape; and
  • 3. A moderate growth rate.

DESCRIPTION OF THE PHOTOGRAPHS

This new cherry laurel plant is illustrated by the accompanying photographs which show the plant's overall plant habit including form, and foliage. The photographs are of a 28-month-old plant grown outdoors in The Netherlands and taken in September 2020. 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 ‘Zsófi’. The data which define these characteristics were collected from asexual reproductions carried out in The Netherlands. Data was collected on two-year-old plants grown outdoors in The Netherlands in September 2020. The range of day temperatures was 18° C. to 34° C. and the range of night temperatures was 10° C. to 20° C. Plants were pinched/pruned three times. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 6^th edition (2015).
