Calla lily plant named ‘Romeo’

Abstract

‘Romeo’ is a new variety of calla lily having beautiful waxy burgundy-red colored spathes.

Description

Botanical classification: Zantedeschia sprengeri.

Varietal denomination: ‘Romeo’.

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 ‘Romeo’.

‘Romeo’ was discovered in 1996 and chosen from a selection of seedling tubers of unknown parentage in Maungaturoto, New Zealand. The first act of asexual reproduction of ‘Romeo’ by tissue culture was performed in 1997 in Auckland, New Zealand. Subsequent asexual reproductions by tissue culture have 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 ‘Romeo’ which, in combination, distinguish this calla lily as a new and distinct cultivar:

1. ‘Romeo’ has a different shaped leaf with fewer leaf maculations than ‘Majestic Red’ (unpatented) and ‘Pink Persuasion’ (unpatented);

2. ‘Romeo’ is taller than ‘Majestic Red’ (unpatented);

3. ‘Romeo’ is more burgundy red than ‘Dominique’ (unpatented), ‘Chianti’ (unpatented), and ‘Carmine Red’ (unpatented); and

4. ‘Romeo’ is taller with a larger spathe than ‘Neon Armour’ (unpatented) and ‘Garnet Glow’ (unpatented).

DESCRIPTION OF THE NEW PLANT

The following observations, measurements, and comparisons describe plants grown in New Zealand under conditions which approximate those generally used in horticulture practice. Plants described were 14 weeks from planting date of tuber. 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.
