This frost tender annual grows to a height of 2 metres. It is grown for its red fruit which make delicious jam or jelly.

Rosella needs a growing season of at least 6 months warm weather so is best suited to tropical or sub-tropical areas. Can be started under glass in cooler areas. Water well and give a dressing of fertiliser when flowering starts.

Culinary hints - cooking and eating Rosella

The large flowers produce a crimson enlarged calyx.
Use the fleshy red calyx, without the green seed pod to make jam or jelly.

Hi Yvette. Could you manage to find seeds for Rosella ? I am also in Mpumalanga and also want to plant some.

Pick rosella when as long as your thumbs first digit. Rinse, cut small slice off base, place thumbs between half way section of calyx and peel back separating seed case from fruit. Place in heavy base pot, water to cover (less is more), simmer until fruit breaks down. Add lemon juice, tblspn per cup of jam, add sugar approx 1/4 cup to cup of jam (the sweetness you like) and bring to rolling boil. always stirring, never allow to stick. When syrupy, coating back of spoon thickly, take of heat, cool slightly and jar. Put jars in oven at approx 110 degrees for 5-10 mins prior to jam pour to sterilize.
