For a family grow 4 to 6 plants; when making the jam, jelly, chutney, or flowers in syrup for later use in champaigne, save some seed pods. Dry them carefully in the sun avoiding rain and birds. Rosellas may be found in the Brisbane Markets most months except July and August. 2009 prices are $4.00 to $7.00 for the firm clean dry fruit. Retail would be from $5.00 to $10.00 per Kg. Packed in new jars and well labeled the jam sells at $4.50 per 300g. Poorly packed in scruffy second or third hand jars 500g may sell for $4.00 if you are silly enough to make it properly and the pack it poorly; either way its a lot of work...two or three boilings of twenty to 30 minutes and lots of sticky red mess on sauspans, seives, jugs, ladles, benches and floors; sugar, lemons, limes and jam thickener all have a place in the jam making. I first made the jam with my parents in 1955 after growing 12 to 16 bushes successfully for my Gardeners Badge in Cubs. The Secret Jam makers business covers the many ways of removing the calyx from the seed pod. HOWEVER THE FLAVOUR IS NEVER FORGOTTEN UNIQUELY QUEENSLAND AND UNSURPASSED. Over the years I' ve raise hundreds of dollars for the Red Cross and Local Churches and given away dozens of jars of Jam. I am trying a recipe I devised for Rusella Butter which should knock Lemon Butter way off the shelves. Rosella Jam made with enough sugar will keep for 12 months below 25 oC, refrigerate after opening. Rosella Butter and Lemon Butter, Lime Butter, Passionfruit, Orange or Banana Butter must be refrigerated at ALL times and then will probably only last 4 or 5 weeks...even less once you open it! Lick your wooden spoons all you Qld. Jam makers. Plant the seeds (rosellas) after the last frost and plant 1 m apart in a sunny spot in well drained soil, applying fertiliser when the flowers first start. The plants may last two seasons but need to be trimmed in wet weather and after fruiting. Thehy are easier to remover after ONE season.

In Toowoomba- is now the right time to plant? I would love to have your rosella jam recipe please, also the 'flowers in syrup' sounds intriguing.

Hi, My rosella plants were growing beautifully, they are at waist high and have now developed spots on the leaves that turn into small holes (not mildew) They are trying to fruit but are struggling, still look great. Does anyone have any ideas on what this may be and a treatment? Regards John

Oakleigh State School in Brisbane has a school fair in September to raise money for the school. The PREP parents are given the task of making products for the Pantry Stall. We are trying to source Rosella as it is a uniquely Queensland taste that is sought after and will add great value to our pantry stall by stocking products made with this fruit. Any help or comments will be really appreciated -Delene

Hi Geoff - would love some of your recipes seeing you have been growing for years. I have tried twice and both times more like cordial than jam so I am doing something wrong. I can grow them no problems at all, but I want to make, jam, wine, cordial etc with them. By the way where do you buy that book?

I have grown rosellas first time in years, thought the plants were dying off but have been flowering and have already picked some for jam, cant remember if we used save the seeds and harvest again!!! Or do the plants continue on? Thanks

Re Anne's tip - I have always boiled up the seeds and used that liquid to pour over the fruit leaves as the seeds contain the pectin to make the jam set better - is this a myth that I have followed faithfully for decades????
