Google about wilting in rosella.

I have no idea - try putting wilting of rosella into google. I would imagine they need a lot of water in the tropics. I had Chinese cabbage like that a month or so ago. A couple of days of warm weather and little water and they just wilted.

To all the questions about rosella planting - if you used this guide to look when to plant and harvest etc you wouldn't ask these questions. This website is a means for you to look up a plant (rosella) set what climate you live in and then read ALL the details about the plant. Plant time, time to harvest, if it is frost tolerant etc. Like if you are cool/mountain it says plant Nov /Dec -- so you don't plant until then.

We are actually on the south coast of Viti Levu, the main island of Fiji. This is a similar latitude to the Whitsundays say half way between Townsville and Cairns but a little less humid as we are on the coast. we grew H.Sabdariffa this year from local seedlings. The flower was yellow and the calyxes only 1.5- 2.5cm and not very fleshy. I believe this version has traditionally been cultivated in Fiji by the Fijian Indians for its young leaf which is a sour spinach used to make chutney. The variety you mention, H.Subdantta looks as though the calyxes is much more fleshy which would suit our end game of producing it as a food source for herbal teas and jams. What color flower does it have? Can you tell me where I can buy seeds from?
