I grew Rosellas for jam last year and though I am no expert, I harvested mine after they had flowered. I left some of mine too long and made more work for myself as they go hard after a while, so take them off when the flower petals have died off, not later into autumn.

I have 3 rosellas bushes about 2 metres tall and very helathy, they have been in about 5 months, but no flowers yet when should they flower and fruit?\

Coastal actually. Planting seeds before the ground has warmed up is frustrating. If you buy seeds, try planting early if you are keen. Some will do okay. Others will sit there and laugh at you before shrivelling. Simply plant another seed. In cool climates it is often pot luck, but they will eventually take off. They will survive and fruit well into autumn, especially in areas where there are no frosts. Pick them in flower daily and put them in the fridge until you have enough. Then boil them gently with a bit of sugar and progressively freeze them. At the end of the season thaw them out and make the jam. Patience is a virtue.

My rosellas have red flowers up stem and are healthy bushy plants. Will they get more flowers on the branches? The few up stems would not be worthwhile.

My plants had an early crop when they were approx.70 centimeters, i would like to know if they will produce another crop. They are about 2 meters high now. Thanks Daphne.

Rosella fruit is best grow in soil in ur garden. As it can grow to 2 metres its restricted in a pot. Ive got bout 30 plants on the property and have just harvested the first lot of fruits. Its a great annual and this year I will sell most of it dried to make into a delicious drink. Lovely member of the Hibiscus!
