Distinct variety of streptocarpus named Velma

Abstract

A new variety of streptocarpus plant is characterized by its amethyst flower having a yellow throat. It has large flowers, long permanence and is generally nonfertile.

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 Velma, formerly named Neptune Rose. The cultivar is an irradiated sport of Neptune Blue.

Velma is virtually identical to Neptune Blue except for the color of the flower.

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 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 eight weeks from a plantlet (a well rooted young plant in a five centimeter pot) to a flowering plant 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. The plant 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 the Royal Horticultural Society of London. Some color reference is to Exotica III and such reference is duly noted.
