  • Rosella bud
    Rosella bud

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.

I have rossella growing and in the past have been successfull however the last two times i have tried to grow these they get to a height of say 400mm and they start a dieback with a white sap like liquid coming out of the bottom of the plant eventually killing it.Any help would be much appreciated we live up in the mountains west of Sarina yes we get frosts however the last rossella plants die back in late summer.

How do you protect the fruits from insect attacks without using pesticide?

Yates have a product called Natures Way Caterpillar Killer - Dipel. This is a natural bacteria spray that is absolutely harmless to everything except caterpillars. It works by disrupting the digestive system in the caterpillar which then dies.

I've started my seeds in a pot..can you tell me about how long until they sprout

From my research Rosella takes 8-10 days to germinate and, as it is sub-tropical, needs warm soil.

I have five bushes.Two are growing well and have produced fruit but not enough for jam.Does anyone know if picked fruit stores well in a fridge until there is enough? And does picking fruit encourage more fruit to grow?

You can freeze them till you have enough from next picking

Rosella is an annual plant. You could save some seed for next season. All the best.

Hi - Are you still in Spain and did you ever get any seeds? Let me know as I have some from Africa. I can spare you a few.
