Description

CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application Ser. No. 62/125,226, having a filing date of Jan. 15, 2015, and entitled “Varieties of Calla Lily Plants”, the entire disclosure of which is incorporated herein by reference.

Botanical classification: Zantedeschia sprengeri.

Varietal denomination: ‘MONTEVIDEO’.

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 ‘Montevideo’.

‘Montevideo’ is a product of a planned breeding program, which had the objective of creating Zantedeschia hybrids for pot 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 selection referred to as C04020 (female parent, unpatented) with Zantedeschia sprengeri ‘Black Star’ (male parent, U.S. Plant Pat. No. 14,844). ‘Montevideo’ was selected in 2007 by the inventor in 't Zand, The Netherlands as one flowering plant within the progeny of the stated cross.

The first act of asexual reproduction of ‘Montevideo’ by tissue culture was performed by the inventor in September of 2010 in 't Zand, The Netherlands. Subsequent asexual reproductions by tissue culture at the same location have demonstrated that the combination of characteristics as herein disclosed for the new cultivar are retained and reproduced true to type through successive generations of asexual reproduction.

The following observations, measurements and comparisons describe plants grown in 14 cm pots in 't Zand, The Netherlands under greenhouse conditions, which approximate those generally used in horticultural practice. Color references are made to The 2001 R.H.S. Colour Chart of The Royal Horticultural Society of London, except where general color terms of ordinary significance are used.

The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

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

• • 1. Dark purple-colored spathe and leaf margin;
  • 2. Inflorescences above the leaf canopy; and
  • 3. High inflorescence production.

Further, when compared to calla lily plant names ‘Schwarzwalder’ (U.S. Plant Pat. No. 11,001), ‘Schwarzwalder’ has an upper surface spathe color of Greyed-Purple Group RHS 187A and a lower surface spathe color that varies between Greyed-Purple Group RHS 187A and Black Group RHS 202A, whereas ‘Montevideo’ has an upper and lower surface spathe color that varies between Greyed-Purple Group RHS 186A and 186B.

Table 1 provides similarities and differences of ‘Montevideo’ to its parents, Zantedeschia sprengeri selection C04020 and Zantedeschia sprengeri ‘Black Star’.
