Rosella is an attractive annual busy plant to 1.5m high with large, lobed reddish leaves and attractive yellow hibiscus-like flowers.
Rosellas are easy to grow, with few pest problems, hardy and productive. Three to four plants is all that is needed to produce a good crop. Plants normally begin to crop when about 3 months old and cropping may continue for 9 months. The fruit is ready to pick about 2-3 weeks after flowering, when they’ll be 2-3 cm across at their widest part.
The fleshy fruit or flower is used to make sauce or jelly with a cranberry flavor.
