Hi my friend, Could you please send to me some hints on how to prepare the rosella jam as your grand mom used to made. Thank you.

Hi Simone, I would love some seeds please. I was over your way this time last year and saw the rosellas there. At the time I had no idea that I would be looking for seeds a year leter. My Mother used to grow them and make jam and she passed away in May and as a tribute to her I plan to grow rosellas on my property so I can think of her and remember the times we spent growing the plants, picking the fruit, separating the seed pod and eating the reward at the end. Thanks for the offer.

Hello Simone I live in Kalgoorlie and would love to grow some rosellas like my mother used to for jam. If you would be so kind as to send me some seeds my PO Box number is 10766 Kalgoorlie WA 6433. Would be happy to send you a mystery env of seed packets if you like or pls name your price. Kind regards Robyn

Rosellas can be used for jam, topping, wine, jelly, chutney, paprika substitute ect. All "fruits" /calyx (the red fleshy cone) are used after the yellow flower opens for a day then dies. Full sized "fruits" take a couple of weeks from flowering and get to around 6cm long 10g+. smallest fruit about 4cm and 5g. Don't let seed capsule dry out. Most recipes require the "flower" to be separated from the seed capsule, can do this with a tool made from a push bike pump handle with 6cm of steel tube. I also eat young leaves of rosella bush. Packet seeds are often available from various seed packet producers check online or better for a quick start get plants in punnets from garden shop.I'm a 2nd generation jam maker growing rosellas sincef cub gardeners badge in early 60's.

My mum has rosella bushes and they have been fully loaded with fruit and before the fruit is ready the bushes are just dying. This is also happening to her neighbour . All her vegetables and roses and gerbera are not having a problem. Any suggestions??
