I've harvested what is probably the last of the Roselle for the season although a few fat red calyxes will probably appear before it's all over. We've had just a few light frosts which didn't bother the plants at all. Saturday morning it will dip to 32 so I'll see just how much cold they can take unprotected.
There were a little over 200 calyxes from three of the four plants. The fourth plant had already been stripped of goodies. I pulled the red sepals from the seed pod and dehydrated them, getting two full quart jars of dried sepals. That's a ton of vitamin C sitting on the shelf now. Here's a shot of the dried sepals and the resulting tea I made from some of them.
I haven't tried making roselle jelly using the green seed pods for their natural pectin. Maybe next year.
