Abstract: A petunia cultivar particularly distinguished by red-purple colored flowers, compact habit and good basal branching.
Claim: I claim:

1. A new and distinct petunia plant as shown and described herein.
Description: Genus and species: Petunia hybrida.

Variety denomination: `Jam Cherose`.


The present invention comprises a new and distinct cultivar of petunia, botanically known as Petunia hybrida, and hereinafter referred to by the cultivar name `Jam Cherose`. The new cultivar is asexually reproduced from vegetative cuttings andtissue culture resulting from the cross of the pollen parent `Red Horizon`, a commercial seed propagated variety that is unpatented .times.99-220-17, a double purple proprietary line that is unnamed and unpatented.

`Jam Cherose` is a product of a planned breeding program intended to create new petunia plants with Red-Purple colored flowers, compact habit, good basal branching and moderately vigorous growth.

The new cultivar was created in 1999 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif., Andijk, The Netherlands, and Guatemala over a three-year period. The plant has alsobeen trialed at Gilroy, Calif., Litchfield, Mich. and Andijk, The Netherlands. The present invention has been found to retain its distinctive characteristics through successive asexual propagations; and this novelty is firmly fixed.


This new petunia plant is illustrated by the accompanying photograph which shows blooms, buds, and foliage of the plant in full color, the colors shown being as true as can be reasonably obtained by conventional photographic procedures.

The Photograph shows the mature flowers.


The following detailed descriptions set forth the distinctive characteristics of `Jam Cherose`. The data, which defines these characteristics, were collected from asexual reproductions carried out in Gilroy, Calif. The plant history was takenon 5 months old plants grown in one-gallon pots in fall/winter season, in a poly-covered greenhouse under 2-4 supplemental light and color readings were taken in the greenhouse in the winter season under natural light. Plants had been cut back numeroustimes prior to data readings taken. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.). Texture description details were observed under a dissecting microscope according to The New RoyalHorticultural Society Dictionary of Gardening (1992).

Not observed.


Compared to its female parent 99-220-17 in the following ways: The female parent has a purple flower color vs. a cherry rose. The female parent has a double flower form vs. a single flower form and the female parent is later to flower.

Compared to its male parent `Red Horizon` in the following ways: Red vs. cherry rose flower color. `Red Horizon` has a more upright plant growth habit than `Jam Cherose`, which is flatter growing.
