| Claim: |
We claim:
1. A new and distinct cultivar of Petunia-Calibrachoa hybrid plant as shown and described herein. |
| Description: |
Genus and species:Petunia.times.Calibrachoa hybrida.
Variety denomination: `Kakegawa S90`.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of Petunia-Calibrachoa and hereinafter referred to by the cultivar name `Kakegawa S90.` It is characterized by having a purple flower color, medium-large flower size and semi-creepinggrowth habit. The new cultivar originated from a hybridization in Kakegawa, Japan in May of 2003. The male parent was a proprietary hybrid Calibrachoa line named `04-62`, having a deep blue flower color, medium flower size and a creeping plant habit. The female parent was a proprietary hybrid Petunia line named `04H-64`, having a light purple flower color, medium flower size and mounding plant habit.
In May 2003, the new Petunia-Calibrachoa variety was developed using an intergeneric cross between a Petunia hybrid and a Calibrachoa hybrid species. After crossing the parent lines, 1,530 ovules were removed from flowers on the female parentand cultured by standard ovule culture techniques. In December 2003, 12 intergeneric hybrid plantlets were transplanted to soilless media for greenhouse culture and acclimization.
In March 2004, 10 plants out of 12 hybrid lines were vegetatively propagated to produce rooted cuttings. In April 2004, the 10 plants were transplanted to an open field and evaluated for flower color and plant growth habit through July. InAugust 2004, `Kakegawa S90` which has a medium-large flower, purple color and semi-creeping plant growth habit was selected and vegetatively propagated.
In September 2004, 10 cuttings were evaluated in an open field through November 2004. The selection subsequently was named `Kakegawa S90` and found to retain its distinctive characteristics through successive asexual propagations.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Kakagawa, Japan. 1. Purple flower color; 2. Medium to large size flowers; and 3. A semi-creepingplant growth habit.
DESCRIPTION OF PHOTOGRAPHS
This new Petunia-Calibrachoa plant is illustrated by the accompanying photographs of an 8-month-old plant which show the plant's form, foliage and flowers. The colors shown are as true as can be reasonably obtained by conventional photographicprocedures.
FIG. 1 shows overall plant habit.
FIG. 2 shows the mature flowers.
DESCRIPTION OF THE NEW CULTIVAR
The following detailed description sets forth the distinctive characteristics of `Kakegawa S90`. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. The detailed description wastaken from plants grown under greenhouse conditions for approximately 8 months from transplanting of rooted cuttings. Color references are to the R.H.S. Colour Chart of The Royal Horticultural Society of London (RHS), 4.sup.th Edition.

Spread.--90.0 cm to 100.0 cm. Propagation: Type cuttings.--Vegetative cuttings. Time to produce a rooted cutting.--4weeks. Time to bloom from propagation.--8 to 10 weeks. Environmental conditions for plant growth: The terminal 1.0 to 1.5 inches of an actively growing stem was excised. The vegetative cuttings were propagated in four weeks. The base of the cuttingswas dipped for 1 to 2 seconds in a 1:9 solution of DIP 'N GROW (1 solution:9 water) root inducing solution immediately prior to sticking into the cell trays. Cuttings were stuck into plastic cell trays having 98 cells, and containing a moistened peatmoss-based growing medium. For the first week, the cuttings were misted with water from overhead for 20 seconds, one time per hour. For the second week, the cutting were misted one time every 2 hours for 10 seconds. After that time, the cuttings weremisted occasionally until sufficient roots were formed. Rooted cuttings were transplanted and grown in 20 cm diameter plastic pots in a glass greenhouse located in Salinas, Calif. Pots contained a peat moss-based growing medium. Soluble fertilizercontaining 20% nitrogen, 10% phosphorus and 20% potassium was applied once a day or every other day by overhead irrigation. Pots were top-dressed with a dry, slow release fertilizer containing 20% nitrogen, 10% phosphorus and 18% potassium. The typicalaverage air temperature was 24.degree. C.

COMPARISON WITH PARENTAL LINES AND KNOWN CULTIVARS
In comparison with its parental lines, Calibrachoa `Kakegawa S90` is a distinct variety of Petunia-Calibrachoa due to its medium to large flowers, purple flower color and semi-creeping growth habit. `Kakegawa S90` is distinguished from itsparents mainly by flower color and plant growth habit as shown in Table 1 below.

Calibrachoa `Kakegawa S90` is a distinct variety of Petunia-Calibrachoa due to its purple flower color and semi-creeping growth habit. `Kakegawa S90` is most similar to the variety `Dancalipet` (U.S. Plant Pat. No. 16,063); however, there aredifferences in the petal color and plant growth habit as described in the table below (color references are to The Royal Horticultural Society Colour Chart, 4.sup.th edition):
