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 - 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.

I don't actually live in United Kingdom, but it was closest to me, I live in Finland, in Northern Europe. Beautiful country with lots of forests and lakes. I googled "Rosella" since that's the name of my dear little sister only 6 years old. I found out it was a bird and was intiqued to see it's some sort of a plant or flower. I'd love to know a little bit more about it, if you can tell me something about the Rosella plant I'd be delighted!!! Have a beautiful autumn all of you, we are now eagerly waiting for the summer to come.. Greetings from the North!!!! <3 Maiju (pronounced My "u") :)
