USPP23614P2 - Zamioculcas zamiifolia plant named ‘LUCKYWHIT’ - Google Patents

Abstract

A new and distinct Zamioculcas zamiifolia cultivar named ‘LUCKYWHIT’ is disclosed, characterized by variegated leaves and a curled leaf margin. The new variety is a Zamioculcas zamiifolia, normally produced as an ornamental plant.

Description

Latin name of the genus and species: Zamioculcas zamiifolia.

Variety denomination: ‘LUCKYWHIT’.

BACKGROUND OF THE INVENTION

The new Zamioculcas zamiifolia cultivar is a product of a chance discovery by the inventor, Edward Bruinen, in Maasdijk, The Netherlands. The inventor identified and selected the interesting mutation of Zamioculcas zamiifolia and proceeded to test its suitability for ornamental commercial applications.

The parent is an unpatented, unnamed variety of Zamioculcas zamiifolia. The new variety was discovered in August 2007 by the inventor as a naturally occurring whole plant mutation, in a commercial greenhouse in Maasdijk, The Netherlands.

Asexual reproduction of the new cultivar ‘LUCKYWHIT’ by vegetative cuttings was first performed at a commercial greenhouse in Maasdijk, The Netherlands in September 2007 and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘LUCKYWHIT’ 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 ‘LUCKYWHIT’ These characteristics in combination distinguish ‘LUCKYWHIT’ as a new and distinct Zamioculcas zamiifolia cultivar:

• • 1. Variegated leaves
  • 2. Curled leaf margin

Plants of the new cultivar ‘LUCKYWHIT’ are similar to plants of the parent, Zamioculcas zamiifolia. in most horticultural characteristics, however, plants of the new cultivar ‘LUCKYWHIT’ produce variegated leaves compared to green leaves. Also the leaf margin of ‘LUCKYWHIT’ is curled whereas the parent is not.

COMMERCIAL COMPARISON

Plants of ‘LUCKYWHIT’ are best compared to the parent variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘LUCKYWHIT’ grown in a greenhouse, in a 17 cm pot. Age of the plant photographed is approximately 18 months from a rooted cutting.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION
