| Abstract: |
A new variety of Streptocarpus plant is characterized by its pure white flower having veined royal purple color. It has large flowers, long permanence and is generally nonfertile. |
| Claim: |
I claim:
1. A new and distinct variety of Streptocarpus substantially as herein shown and described. |
| Description: |
BACKGROUND OF THE NEW PLANT
The present invention comprises the new and distinct cultivar of Streptocarpus x hybridus known by the varietal name Ilsa, formerly named Juwel. The new cultivar is an irradiated sport of a Streptocarpus known by the varietal name of Laura.
The major difference when compared with Laura is in color, Laura having a blue flower. In addition, the new cultivar has larger and more persistant blooms and is nonfertile as compared to Laura.
The new cultivar was discovered in 1977 in Vaihingen, Federal Republic of Germany; was first asexually reproduced by cuttings in Vaihingen, Federal Republic of Germany; and has been repeatedly asexually reproduced by cuttings at Oglevee FloralCompany in Connellsville, Pa. It has been found to retain its distinctive characteristics through successive propagations.
The new cultivar, when grown in a greenhouse in Connellsville, Pa., has a response time of nine weeks. Response time is defined as the period of time from a plantlet which is a well rooted young plant in a five centimeter pot to a floweringplant in a ten centimeter pot.
DESCRIPTION OF THE DRAWING
The accompanying drawing illustrates the new cultivar, the color being as nearly true as possible with color illustrations of this type.
DESCRIPTION OF THE NEW PLANT
The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected from asexual reproductions carried out by the Oglevee Floral Company in Connellsville, Pa. Theplant history was taken on eight week plants blossomed under natural light in a greenhouse and color readings were taken indoors under 100 foot candles of cool white fluorescent light. Color references are primarily to the R.H.S. color chart of theRoyal Horticultural Society of London. Some color reference is to Exotica III and such reference is duly noted.
