ABSTRACT:
Botanical classification:
Zantedeschia sprengeri.
Varietal denomination: ‘Black Star’.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct cultivar of calla lily, botanically known as
Zantedeschia sprengeri
and herein after referred to by the cultivar name ‘Black Star’.
‘Black Star’ 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 cross of a
Zantedeschia sprengeri
variety known as ‘Schwarzwalder’ female patent (U.S. Plant Pat. No. 11,001), with a
Zantedeschia sprengeri
seedling, male parent. ‘Black Star’ was orginated in 1998 by the inventor Cecilius Jan-Jochem Randag in 't Zand, The Netherlands as one flowering plant within the progeny of the stated cross.
Table 1 provides a comparison of the new variety to its parents:

The first act of asexual reproduction of ‘Black Star’ by tissue culture was performed by the inventor in August 2000 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 be basic characteristics of ‘Black Star’ which, in combination, distinguish this calla lily as a new and distinct cultivar:
1. Deep purple spathe;
2. Deep purple spadix;
3. Red flower stem;
4. Red edge on the leaves; and
5. Red/black petiole of the leaves.
