Hi, you can pick them once the calyx has firmed up.

I would like to preserve the rosella flowers for a friend, like they do commercially for the bottom of your champagne glass. Can anyone help?

Lisa, I've never seen the flowers like this - are they dried out or soft enough to eat when you've finished your champagne?

They're usually preserved in syrup, so they're a bit chewy at the end of the champagne but quite edible.

To dry the rosellas, separate the seed and dry the red calyx in an electric dehydrator. Use the dried flesh for a lovely cup of tea, adding sugar if desired. I made some teabags from dressmakers light interfacing, from the drapers, adding a cotton thread tag.

I usually plant seedlings in Sept/Oct. This year we had several weeks of continuous rain and although the plants grew I have not got much fruit from them to date. Now they are flowering but tend to be wilting from the top and will probably die. Can anyone give me a tip to correct the problem

how do you get the seed out of the rosella fruit. When can you purchase a seed podder for them.

Hi Sue, Use an apple corer, it works really well. Push it through from the bottom up. Good luck, it makes beautiful jam and cordial.

I have a Rosella Bush growing and at present it is about 1.5mtr high and about the same in width, this is my first experience of growing one. It is absolutely covered in fruit, however I am not sure on how big they will grow before I am able to pick them. Could someone please advise me on this? thank you

Hi Joy, They can be harvested at any time, once the calyx has firmed. Some grow up to the size of a walnut, others hazelnut. And remove the seed with an apple corer, it's quite easy that way.
