Abstract

A new and distinct cultivar of Rex Begonia plant named ‘Denver Lace’, characterized by its uniform growth habit; moderate plant vigor; no requirement for winter dormancy; and interesting and attractive leaf coloration and pattern.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia rex hybrid, commercially known as Rex Begonia, and hereinafter referred to by the name ‘Denver Lace’.
The new Rex Begonia was discovered and selected by the Inventor in a controlled environment in Vista, Calif., in 1995, within a large group of seedling progeny from multiple crossings of unidentified selections of Begonia rex hybrids.
The selection of this plant was based on its uniform growth habit, moderate plant vigor, salt tolerance and attractive foliage coloration and pattern.
Asexual reproduction of the new Rex Begonia by leaf cuttings taken in a controlled environment in Vista, Calif., has shown that the unique features of this new Rex Begonia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar ‘Denver Lace’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength 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 ‘Denver Lace’. These characteristics in combination distinguish ‘Denver Lace’ as a new distinct and Rex Begonia:
1. Uniform growth habit.
2. Moderate plant vigor.
3. Does not require winter dormancy.
4. Interesting and attractive leaf coloration and pattern.
In side-by-side comparisons conducted by the Inventor in Vista, Calif., plants of the new Rex Begonia differ from plants of the nonpatented cultivar Merry Christmas Corkscrew in the following characteristics:
1. Plants of the new Rex Begonia have larger and flatter leaves than plants of the cultivar Merry Christmas Corkscrew.
2. Plants of the new Rex Begonia are more vigorous than plants of the cultivar Merry Christmas Corkscrew.
3. Leaves of plants of the new Rex Begonia and the cultivar Merry Christmas Corkscrew differ in coloration and pattern.
4. Leaves of plants of the new Rex Begonia do not have a “corkscrew” formation whereas leaves of plants of the cultivar Merry Christmas Corkscrew have a “corkscrew” formation.
5. Plants of the new Rex Begonia do not require a winter dormancy period whereas plants of the cultivar Merry Christmas Corkscrew do require a winter dormancy period.
In side-by-side comparisons conducted by the Inventor in Vista, Calif., plants of the new Rex Begonia differ from plants of the nonpatented cultivar Lillium in the following characteristics:
1. Plants of the new Rex Begonia are more compact than plants of the cultivar Lillium.
2. Plants of the new Rex Begonia have larger and flatter leaves than plants of the cultivar Lillium.
3. Leaves of plants of the new Rex Begonia and the cultivar Lillium differ in coloration and pattern.
4. Plants of the new Rex Begonia do not require a winter dormancy period whereas plants of the cultivar Lillium do require a winter dormancy period.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Rex Begonia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The photograph comprises a top perspective view of a typical plant of ‘Denver Lace’. Foliage colors in the photograph many differ from the actual colors due to light reflectance.
