Abstract: A new geranium cultivar is distinguished by its brilliant color, short and compact plant, more basil branching, close internodes, small leaves and short flower stems with the flowers positioned immediately atop the foliage. The new cultivar further provides early flowering and is more floriferous as compared with commonly grown zonal geraniums.
Claim: I claim:

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

The present invention comprises a new and distinct cultivar of Pelargonium hortorum, Bailey known by the varietal name of Alex. The new variety was discovered in a selective breeding program and is a seedling resulting from the cross of the seedparent Dresdner Rubin Selection X Walter Dietzmann and the pollen parent Dresdner Rubin Selection.

The new cultivar was discovered in the year 1973 in Dresden, German Democratic Republic; was first asexually reproduced by cuttings in Dresden, German Democratic Republic and has been repeatedly asexually reproduced by cuttings at Oglevee FloralCompany in Connellsville, Pa. over an eighteen month period. It has also been trialed and field tested at Connellsville during the summers of 1981 and 1982. It has been found to retain its distinctive characteristics through successive propagations.

The new cultivar, when grown in a greenhouse in Connellsville, Pa., using natural light and F. night temperature and F. day temperature, has a response time of five weeks from a well rooted cutting to a flowering plant ina four inch (10 cms.) pot.


FIG. 1 of the accompanying photographic drawing illustrates the new cultivar, the color being as nearly true as possible with color illustrations of this type.

FIG. 1 is a graph of the flavonols fingerprinting,

FIG. 2 is a graph of flavonols fingerprinting and

FIG. 3 is a graph of the anthocyanins fingerprinting of the new cultivar.


The following detailed descriptions set forth the characteristics of the cultivar. The data which define these characteristics were collected from asexual reproductions carried out by the Oglevee Floral Company in Connellsville, Pa. The planthistory was taken on five week plants, blossomed under natural light in a greenhouse and color readings were taken indoors under 100 foot candles of cool, white florescent light. Color references are primarily to the R.H.S. Colour Chart of The RoyalHorticultural Society of London.

Disease resistance: Better than average to Botrytis.

Lasting quality: On the order of three weeks.



Anthers.--Imperfectly formed on flattened filaments; resemble petaloids 2 to 6 in number.

Filaments.--Streaked white and red to red; growing together with petaloids, 6 in number; nonuniform; 0.5 to 1 cm. in length.

Pollen.--Golden yellow, very little pollen.



Length.--1 cm.

Stigma.--5 Arms upright, reddish purple in color, similar to base of petal.

Style.--Reddish purple.

Ovaries: Green, 5 carpels.

Fruit: Nonfertile.

The following evaluation is a result of the trialing and field testing carried out in the summer of 1982 at Connellsville, Pa. and compares the new geranium cultivar to the standard cultivar "Irene" presently commercialized in the United States. The ratings are taken on plants planted in June and evaluated at three different times throughout the summer. The plants were evaluated as to height, flowering, number of flowers, heat tolerance and form. The rating is based on a weighted average. Arating of 1.0 is poor and a rating of 10.0 is outstanding.

The new cultivar is characterized by its brilliant color and its short and compact plant. There is more basil branching and close internodes and small leaves as compared with the standard bush zonal geraniums produced in the United States. Ashort flower stem positions the flower immediately atop of the foliage into the plant and renders the plant very resistant to wind and rain damage. The plants provide early flowering and are more floriforous as compared to the standard United Statesvarieties.

The new cultivar has been fingerprinted by the U.S. Department of Agriculture, Florist and Nursery Crops Laboratory, Beltsville, Md. Young plants arrived from Oglevee Floral Company of Connellsville, Pa. and were grown under standardconditions in a greenhouse at Beltsville, Md. The fingerprinting was conducted by high pressure liquid chromatographic analysis of the anthocyanin and flavonol chemical markers utilizing flower petals as an adjunct for cultivar identification. Petalswere selected for analysis from individual mature flowers sampled just after anthesis. It should be noted that changes in environment can influence the biosynthesis of the flavonoids. The absorption profiles (fingerprints) are illustrated in FIG. 2 and3.
