Hi Rae, I notice my regular seed supplier sells these. It won't let me paste the link but if you google 'the seed collection australia' you should find them. Best wishes.

Do they fruit once and the tree dies

No they have not even flowered or fruited yet?

I live in one of the warmest climate zones in Canada on Vancouver Island and would like to grow rosella here on the coast of the Salish Sea. I was wondering if they would grow as a protected annual here, or with luck a perennial?

I live in Vancouver,BC and would like to grow them too. Have you already tried? I think I'll start seeds and grow them in my greenhouse.

Do you pull out plants when finished fruiting or can you leave them in for the next season?

I pull mine out each year when they are past their prime and the seed pods are bursting open.

I have grown rosellas for the first time. They are about 2400mm high and very wide and producing lots of fruit. I've been making jam and cordial [delicious] as well as giving lots away. I can't believe how well they have done and how easy to grow. .I can pick at least a bucketful a week. Tips: I watered them when young and haven't done anything else since except pick. I use scissors to cut off fruit.

I've got 4 successful seedlings all about 10cm high. I grew them in a strawberry container on the window sill in the kitchen. Soon I'm going to transplant them into pots. I'm hesitant as by June it is winter here, and it gets very very cold, hence my reason for large pots, I'll keep them either inside or under the verandah. Has anyone else got any tips?

Ok... So I have purchased Rosella seeds and will try to raise. I live in Townsville and wondering if anyone has any tips for me?
