Abstract
In Western Europe Hibiscus has been cultivated as a flowering potplant for many years.
They are supplied to the market during spring and early summer, as they need a lot of light for flower formation and development.
To produce a compact plant a frequent spray with Cycocel (CCC) is necessary, as the cultivated varieties form many leaves before they initiate flower buds in the axils and the internodes are rather long.
The repeated sprays with Cycocel cause an accumilation of this retardant in the top of the branches by which the plants grow very slowly by the consumer.
The aim of this project was to develop varieties which can be supplied to the market for a longer time without the use of growth retardants.

The aim of this project was to develop varieties which can be supplied to the market for a longer time without the use of growth retardants.
By breeding and selection new varieties have been developed which initiate the first flower buds already in the third up to the fifth leaf axil, dependant on the time of the year and pinching.
This means earlier flowering, no spraying with growth retardants and continuous flowering plants for the consumer.
