USPP13393P2 - Variety of calla lily plant named ‘Purple Haze’ - Google Patents

Abstract

‘Purple Haze’ is a new variety of calla lily having an inflorescence with a purple colored spathe and a yellow and purple colored spadix and producing 1-6 inflorescences per tuber. The leaves are dark green with whitish spots and have a leathery texture.

Description

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of calla lily, botanically known as Zantedeschia sprengeri and hereinafter referred to by the cultivar name ‘Purple Haze’.

‘Purple Haze’ is the product of a planned breeding program which had the objective of creating Zantedschia hybrids for cut flower production in a wide range of colors with a large, classic flower shape. The breeding program began in 1989 and the new cultivar is a seedling selected from the crossing of a Zantedeschia sprengeri variety known as ‘Cameo’, seed parent (unpatented), with a Zantedeschia sprengeri variety knows as ‘Best Gold’, pollen parent (unpatented). ‘Purple Haze’ was originated in 1995 by the inventor in 't Zand, The Netherlands, as one flowering plant among the progeny of the stated cross. ‘Cameo’ has pink colored spathes and ‘Best Gold’ has yellow colored spathes, while ‘Purple Haze’ has purple colored spathes with yellow edges.

The first act of asexual reproduction of ‘Purple Haze’ by tissue culture was performed by the inventor in August 1995 in 't Zand, The Netherlands. Subsequent asexual reproduction by tissue culture at the same location has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are retained through successive generations of asexual reproduction.

The following traits have been repeatedly observed and determined to basic characteristics of ‘Purple Haze’ which, in combination, distinguish this calla lily as a new and distinct cultivar:

1. Purple spathe with a yellow edge;

2. Purple/yellow spadix;

3. Number of inflorescences per tuber.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety, with the colors being as nearly true as is possible with color illustrations of this type.

DESCRIPTION OF THE NEW PLANT

The following observations, measurements and comparisons decsribe plants grown in 't Zand, The Netherlands under greenhouse conditions which approximate those generally used in horticultural practice. Age of the observed plant was two years after tissue culture. The observed plant was grown in a container with an 18 cm diameter. Color references are made to The R.H.S. Colour Chart of The Royal Horticultural Society of London, except where general color terms of ordinary significance are used.
