Description
BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Pelargonium.times.hortorum known by the varietal name `Fireball` (Oglevee No. 5084, Breeder No. 4DG872). The new variety was discovered in a selected breeding program in Lompoc, Calif. as a cross between `Tango` (U.S. Plant Pat. No. 5,933) and `Victoria` (U.S. Plant Pat. No. 6,064). The new variety was first asexually reproduced by cuttings at Oglevee, Ltd. in Connellsville, Pa. on Feb. 22, 1995. The new variety has been asexually reproduced by cuttings at Oglevee, Ltd. in Connellsville, Pa. over a several year period. It has also been trial and field tested at Connellsville and has been found to retain its distinctive characteristics through successive propagations.

The cultivar, when grown in a glass greenhouse in Connellsville, Pa. using natural light and temperatures of 60.degree. F. night and 68.degree. F. day, has a response time of six weeks from a rooted cutting to flowering in a 10 cm pot. The response time was determined on plants grown in soilless media employing constant fertilizer 200-250 parts per million of nitrogen and potassium in full light.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawing illustrates the new variety, with the color being as nearly true as is possible with color illustrations of this type.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions carried out by Oglevee, Ltd. in Connellsville, Pa. The plant history was taken on six week plants blossomed under natural light in a greenhouse and the color readings were taken on a plant grown in a 20 cm pot on Feb. 24, 1998 indoors under 200-220 foot candles of fluorescent cool white light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.

GENERAL CHARACTERISTICS

`Fireball` was selected as a replacement for the current variety of `Red Hots` (U.S. Plant Pat. No. 9,305). The variety was tested over a three-year period against `Red Hots` and also `Tango` (U.S Plant Pat. No. 5,933). It was found to be superior to both in greenhouse and outdoor garden trials withstanding either high temperature and low moisture or low temperature and high moisture. Indoors it was at least 7 days earlier than `Tango` and did not show petal burning which is very prevalent in `Red Hots`. Its neat plant habit allows for tighter growing. Cutting production is equal to that of `Red Hots` and better than `Tango`. Rooting speed is very acceptable at 21 days. `Fireball` finishes as a neat medium mound of dark green foliage with a burst of bright intense red flowers.

Claims

1. A new and distinct variety of geranium plant substantially as shown and described.
