Abstract

A new and distinct Begonia cultivar named ‘Nzcfour’ is disclosed, characterized by its unique foliage and stem coloration. The new cultivar is a Begonia, typically suited for garden and ornamental container use.

Description

Latin name of the genus and species: Begonia boliviensis×micranthera.

Variety denomination: ‘Nzcfour’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The new variety originated from a cross pollination of the seed parent, an unpatented, variety of Begonia boliviensis×micranthera with the pollen parent, an unpatented variety of Begonia boliviensis directed by the inventor in February of 2007. The crossing was made in Palmerston North, New Zealand, at a commercial greenhouse.

‘Nzcfour’ was selected by the inventor, Ed Morgan in August 2007 in Palmerston, New Zealand at a commercial greenhouse among seedlings resulting from the February 2007 crossing.

After selection of the new cultivar, asexual reproduction of ‘Nzcfour’ was first performed in the same commercial greenhouse by vegetative cuttings in December of 2007. ‘Nzcfour’ has since produced several generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Nzcfour’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Nzcfour.’ These characteristics in combination distinguish ‘Nzcfour’ as a new and distinct Begonia cultivar.

- 1. Distinctive Greyed-Purple color of underside of foliage.
- 2. Unusual bronze/purple colored stems.

PARENTAL COMPARISON

Plants of the new cultivar ‘Nzcfour’ are similar to the female parent in most horticultural characteristics. However, ‘Nzcfour’ differs in producing different colored flowers.

Plants of the new cultivar ‘Nzcfour’ are similar to the male parent in most horticultural characteristics. However, ‘Nzcfour’ differs in producing foliage of a different color.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘Nzcfour’ are similar to the commercial variety ‘NZCTWO’ U.S. Plant Pat. No. 21,177 in most horticultural characteristics. However, ‘Nzcfour’ differs in producing different color flowers than, ‘NZCTWO’ and darker stems.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘Nzcfour’ grown in a greenhouse in Palmerston North, New Zealand. This plant is approximately 2 years old, shown in a 2 liter pot. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2001 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘Nzcfour’ plants grown in a greenhouse in Stuttgart, Germany. Temperatures ranged from 16° C. to 20° C. at night to 18° C. to 20° C. during the day. No artificial light, photoperiodic treatments or chemical treatments were given to the plants. Measurements and numerical values represent averages of typical plant types.
