Sardis

Abstract

An original variety of gerbera plant distinguished by a red color of its flowers, and its ability to grow vigorously and flower profusely during the spring, midseason, and fall blooming periods as well as blooming in the winter in the greenhouse.

Description

BACKGROUND OF THE PLANT

This gerbera variety, named `Sardis`, originated as a seedling at Rijsenhout, and resulted from the crossing in March of 1981 of 78-817 as the seed parent and the pollen parent identified as 77-224, taken from my collection of gerbera maintained for breeding purposes at Rysenhout, the Netherlands. My objective in making the crossing being to develop new gerbera varieties having blooms of good quality and excellent color on strong plants having good winter production in my greenhouses. This plant was selected from the seedlings resulting from the above crossing because of its big semi-double flower having a particularly intensely red flower coloration, and its vigorous and strong growth habit. The characteristics embracing the above objectives along with other desirable improvements as set forth below distinguish this new plant from its parents as well as from all other varieties of which I am aware.

The varieties thought to be most similar are `Vesta`, `Marleen` and `Atlas`. `Sardis` is distinguished from `Vesta` by its better color, semi-double, and stronger flower stem. `Sardis` is distinguished from `Marleen` by its different floral color, and semi-double, bigger flower. `Sardis` is distinguished from `Atlas` by its more intensive color, and semi-double, bigger flower.

Asexual propagation of this selected plant was carried on under my direction at Rysenhout by cuttings and further by means of tissue culture at Naaldwijk, the Netherlands, through several successive generations which clearly demonstrated that the novel characteristics of its blooming and growth habits appear to be firmly fixed and would remain true from generation to generation.

The following is a detailed description of my new gerbera plant based upon observations of greenhouse plants grown at Naaldwijk, Netherlands, the color designations being according to The R.H.S. Colour Chart published by The Royal Horticultural Society of London, England.
