Abstract

The new cultivar is generally characterized by its two-tone rose pink and purple coloration and its distinct veining. It is also characterized by flower stalks which are open and of irregular length.

Description

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Streptocarpus .times. hybridus known by the varietal name of Orchis. The new cultivar was developed in a breeding program and is a cross of the varieties Fiona (pollen parent) and Karen (seed parent). The new cultivar is distinguished from its parentage by its brighter color, yellow throat and early blooming. It is similar to its parentage in respect of its pink color, design of flower and strong peduncles.

The new cultivar is generally characterized by its two-tone rose pink and purple coloration and its distinct veining. It is also characterized by flower stalks which are open and of irregular length.

The new cultivar was discovered in 1978 in Hedingen, Switzerland; was first asexually reproduced by cuttings in Hedingen, Switzerland; and has been repeatedly asexually reproduced by cuttings at Oglevee Floral Company 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. This response time is measured from a plantlet which is a well rooted young plant in a five centimeter pot to a flowering plant in a fifteen 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. The plant history was taken on nine week plants blossomed under natural light in a greenhouse and color readings were also taken using natural sunlight. Color references are primarily to the R.H.S. color chart of The Royal Horticultural Society of London. Some color reference is to Exotica III and such reference is duly noted.
