PATENT ABSTRACT
A new and distinct Pelargonium×hortorum cultivar named BFP-420 Bright Red is provided. This new Zonal Geranium cultivar was the result of a controlled breeding program wherein a plant designated BFP-56 (non-patented in the United States) was pollinated by a plant designated 3113D. The new plant forms attractive dark red semi-double florets and medium green foliage with attractive zonation. A medium self-branching growth habit is exhibited in the absence of a growth regulator.

PATENT DESCRIPTION
SUMMARY OF THE INVENTION 
     The present invention comprises a new and distinct Geranium cultivar, botanically known as Pelargonium×hortorum Bailey, and hereinafter is referred to the cultivar named BFP-420 Bright Red. 
     The new cultivar is the product of a planned breeding program which had as its objective the creation of a new Geranium cultivar that exhibits uniform flowers, medium green foliage, a medium self-branching growth habit that requires no growth regulator, a propensity for rapid rooting, and a stable foliage coloration during shipment. 
     The breeding program that resulted in the production of the new cultivar of the present invention was carried out during 1989 at Arroyo Grande, Calif., U.S.A. The female parent (i.e., seed parent) was plant designated BFP-56 (non-patented in the United States) which exhibits semi-double red florets with light green foliage. The male parent (i.e., pollen parent) was a plant designated 3113D (non-patented in the United States) which exhibits semi-double dark red florets and medium green foliage with a distinct zone. The parentage of new BFP-420 Bright Red cultivar can be summarized as follows: 
     
         BFP-56×3113D. 
    
     BFP-420 Bright Red was discovered and selected during 1990 as a highly distinctive flowering plant from among the progeny of the stated cross at Arroyo Grande, Calif., U.S.A. This plant was initially designated BFP-420. 
     It was found that the new cultivar of the present invention: 
     (a) exhibits attractive dark red semi-double florets, 
     (b) forms medium green foliage with zonation, and 
     (c) exhibits a medium self-branching growth habit in the absence of a growth regulator. 
     When plant material of the BFP-420 Bright Red cultivar is subjected to standard random amplified polymorphic DNA marker analysis (RAPD) using polymerase chain reaction (PCR) and a known set of DNA primers, it is found to exhibit a distinctive fingerprint map which is on file at the Ball FloraPlant Division of Geo. J. Ball, Inc. at Arroyo Grande, Calif., U.S.A. 
     The first act of asexual reproduction of BFP-420 Bright Red was accomplished when vegetative cuttings were taken from the initial selection in a controlled environment at Arroyo Grande, Calif., U.S.A. by a technician working under the direction and supervision of the originator of the new cultivar. Horticultural examination of plants resulting from such asexual propagation during 1990 has demonstrated that the combination of characteristics as herein disclosed for the BFP-420 Bright Red cultivar are firmly fixed and is retained through successive generations of such asexual reproduction. 
     The new BFP-420 Bright Red cultivar has not been observed under all possible environmental conditions. Accordingly, the described phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length. 
     Of the many commercially available Geranium cultivars, the Sassy Dark Red cultivar (U.S. Plant Pat. No. 8,053) is considered to be most similar to the new BFP-420 Bright Red cultivar. When the new cultivar of the present invention is compared to the Sassy Dark Red cultivar, the BFP-420 Bright Red cultivar exhibits smaller umbels, (e.g., approximately 9.0 to 9.5 cm.×6.0 to 6.2 cm. vs. approximately 9.5 to 11.0 cm.×6.0 to 7.0 cm.), more florets per umbel (e.g., approximately 39 to 41 vs. 30 to 37), and more petaloids per floret (e.g., 2 to 3 vs. 1 to 2). 
     The new cultivar of the present invention is being marketed by Geo. J. Ball, Inc. under the Designer trademark. 
    
    
     BRIEF DESCRIPTION OF THE PHOTOGRAPH 
     The accompanying photograph shows a typical plant of the new BFP-420 Bright Red cultivar with colors being as nearly true as it is reasonably possible to make the same in a color illustration of this character. Typical flowers and foliage are depicted. The plant was grown in a greenhouse at West Chicago, Ill., U.S.A. 
    
    
     DETAILED DESCRIPTION 
     The following observations, measurements and comparisons describe plants grown in Ball FloraPlant&#39;s greenhouses at West Chicago, Ill., U.S.A. under conditions which approximate those generally used in commerical practice. In the following description, color references are made to The R.H.S. Colour Chart of The Royal Horticultural Society, London, England. The color values were determined between 9:00 and 10:00 a.m. on Jul. 21, 1994, under natural light conditions of 2,000 footcandles.
