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

Your question is beyond the scope of this site. I have contacted the Queensland Department of Agriculture and Fisheries and they said for you to get in touch with Sarah Lempus on (07) 4797 9725 or Sue Heisswolf on (07) 4797 9744. They are based in Bowen and should be able to help you. All the best with your venture.

Hello I am hoping to find someone to make Rosella jam. That I can sell along with my own jams in WA. I get asked for it constantly. Would need to have a registered kitchen. Thanks Lana

I live in Darwin. I just threw out a lot of seeds into the bare paddock in Oct and let them grow naturally. After the monsoons best crop!

I have saved seeds from last years Rosella's plants. What is the best time to sow the seeds for this years planting. Have some in seed mix at the moment, but nothing happening after two weeks.I think it may be still to cold yet. Am at Port Stephens on the coast nsw. For what it's worth, I mix manderine and orange pulp with my rosella jam. Feed back is very positive for taste and appearance. Delicious jam.

Hi I am wanting to plant out my Rosella seedlings in a few weeks and need to know the ph of the soil. The plants in the garden are growing well so have a good level of fertility. This day the ph was 7 being neutral, thanks.

Every year I get my Rosella plants online from plantanative.com.au. They have them available around Sept. You can even email them and be on their waiting list too. Great quality plants and price
