how do you get the green seed out of the calyx without cutting the calyx? I want to do some in syrup but can't seem to get the "flower" whole

To remove the seed leaving a full fruit you should take a thin slice from the base of the fruit and push the seed out with a chopstick from the thick end to the pointy end. The seed will gently part the petals and pop through. Easy as! I can seed a bowl of fruit in less than five minutes.

It's fussy work for you and very tedious but if you'd like to try this method. My wife, Janine and I were shown the following: Get the stem of a broken umbrella; push that up through the petals; the seed pod (calyx) will pop through.

When I was a child my father made a "Rosella de-leafer" by attaching an empty bullet casing to a handle - it worked well & I still have it. Maybe you could try an apple corer?

My dad did the same for my mum out of a piece of metal gal tube or stainless tube (I think it was out of a bicycle pump??) He put a bit of tube over it so it wasn't sharp for a handle, works a treat. I still have the one that he made for me as well.

We found that around September was about the best time.

Just had my wilting rosella plants diagnosed by the nursery where I bought them. They said it was typical of too much rain/water - so grow them high and don't mulch during heavy rainy periods like - A nematode or two on roots but not enough to kill a plant starting to flower like mine - suggested to water with a weak solution of condies crystals and interplant with marigolds to discourage nematodes. Bought 4 new plants to try again now that the big wet seems gone.
