Do Bunnings in Townsville,queensland have rosella plants suitable to grow in the tropics

I planted my 12 Rosella seedlings that I got from Bunnings in Late October 2014. in January I harvested the first crop and made some very tasty jams. I then made a second harvest (a little more that half the first) Yes you guessed it jammed that too. They are still growing and delivering though less and less each time. They are getting regular watering either from the rain or irrigation.

I was living in an area of B.C. CANADA where winter temperatures got down below minus 35 degrees. Sometimes I could start my Rosellas indoors in big pots in April and by May long weekend could move them outside into a sunny spot. By end of August I could harvest enough fruit for several pots of jam and a few left over for next years seeds. If you're careful one could grow all sorts of them in southern Australia as it is a heck of a lot colder in Canada and the jam is great...you can eat the leaves and stalks if you're into that. It is colder there for sure but sunup is before 4am and sundown is after 10 pm so that extra sunlight helps

Dorothy, I would love your Rosella cordial recipe. Just made a very succesful batch of orange and lemon cordial for chrissy presents, and am looking forward to experimenting with other recipes. Thanks in advance for your post :)

I use my rosellas for making jam but also cordial. It is really nice. You can use any fruit however rosella cordial has a very different flavour. If you want the recipe, please e mail this site and I will post it on this site.

Sheila mentioned that she sells the plants. I'm in Brisbane and would love to buy 1 or 2 for my backyard. Where are you in Caboolture?

I have two types of rosella plant. One has large seeds, and not much flesh. They have different types of leaves, and the fruit is shaped differently.The pointed fruit variety is easier to seperate the flesh from the seeds and has more flesh. More jam

We grow and sell the bushes from Caboolture, north of Brisbane if anyone is interested. The plants have three crops a year and three bushes will make about two dozen jars of jam. Leaves have a lemon flavour and can be used in cooking.

Is it true that there are a couple of different varieties of rosella? Where can one seeds or plants? I've heard comments regarding the success of my mother's succulent jam as compared to others bought which are somewhat dry - any reason for this?

My seeds of Rosella did not germinate - anyone have seeds for assae?

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.
