Description

The present invention relates to a new and distinct cultivar of begonia plant, botanically known as Begonia hiemalis (Fotsch), and known by the cultivar name `Edinburgh.`

The new cultivar `Edinburgh` is the product of a planned breeding program. The female or seed parent was a proprietary tuberous Begonia selection designated Code No. 1004890-1 and the male or pollen parent was a proprietary selection of B. socotrana designated Code No. 109. `Edinburgh` was asexually propagated for the first time in May 1990 in Marslev, Denmark. Continuous asexual propagation by tip cuttings has demonstrated that the combination of characteristics as herein disclosed for the new cultivar `Edinburgh` are firmly fixed and are retained through successive generations of asexual reproduction.

The following characteristics distinguish the new begonia from both its parent and other begonias commercially known and used in the floriculture industry:

1. `Edinburgh` has purple-red flowers unlike any other known hiemalis begonia. It is more purple than `Cheers` (U.S. Plant Pat. No. 6,013) or `Lancelot` (U.S. Plant Pat. No. 6,928).

2. `Edinburgh` is vigorous and tall like `Schwabenland Red` (U.S. Plant Pat. No. 3,320) and `Lancelot` but unlike the more compact variety `Cheers.`

3. `Edinburgh` has double flowers in contrast to the single flowers of `Schwabenland Red.`

4. Foliage of "Edinburgh` is not as deeply lobed as those of `Lancelot.`

5. The flowers of `Edinburgh` are not ruffled like those of `Cheers.`

`Edinburgh` has not been tested under all available environmental conditions and the phenotype may vary with variations in environmental conditions such as temperature, light intensity, daylength and humidity without a change in the genotype of the plant variety.

The accompanying color photograph taken August 1993 illustrates the overall appearance of this cultivar taken as an oblique view of the plant grown in 12 cm plastic pot and showing the colors as true as it is reasonably possible to obtain in a colored reproduction of this type.

The following is a detailed description of the new begonia cultivar based on plants produced under commercial practices in Hannover, Germany and Ashtabula, Ohio. Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) except where general terms of ordinary dictionary significance are use.
