Abstract

‘Picasso’ is a new variety of calla lily having a flower with a yellow-orange/purple colored spathe producing 1-15 flowers per tuber. The flower stems are about 50 cm in height. The leaves are green with many whitish spots and have a leathery texture.

Description

Botanical classification: Zantedeschia sprengeri.

Varietal denomination: ‘Picasso’.

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 ‘Picasso’.

‘Picasso’ is a product of a planned breeding program which had the objective of creating Zantedeschia 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 seedling 92839 (female parent, unpatented) with a Zantedeschia sprengeri seedling 92864 (male parent, unpatented). ‘Picasso’ was originated in 1998 by the inventor C. J. J. (Cecilius Jan-Jochem) Randag in 't Zand, The Netherlands as one flowering plant within the progeny of the stated cross.

The first act of asexual reproduction of ‘Picasso’ by tissue culture was preformed by the inventor in August 2001 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 Picasso which, in combination, distinguish this calla lily as a new and distinct cultivar:

1. White-Purple spathe;

2. Fast forcing time; and

3. High flower production.

Table 1 provides similarities and differences of ‘Picasso’ to its parents and the Zantedeschia sprengeri variety ‘Cameo’ (unpatented):

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:

FIG. 1 is a close-up photograph of three ‘Picasso’ flowers;

FIG. 2 is a photograph of a single flower of the new variety; and

FIG. 3 is a field of ‘Picasso’ clones.

DESCRIPTION OF THE NEW PLANT

The following observations, measurements and comparisons describe plants grown in 't Zand, The Netherlands under greenhouse conditions which approximate those generally used in horticultural practice. 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.
