Green Roselle? Does that mean the dried flowered bracts are green, not burgundy?
As far as I know yes. I imagine that the flowers are also going to lack the red "throat" they normally have.
I've often wondered about roselle. I grew some plants about 4 years ago, I don't know what specific kind they were, just 'regular red' I guess. But they did actually flower and produce seed for me, not much, but I think I only grew about 8 plants. But I've read several times that you have to be careful which roselle 'variety' you get because some, maybe most, won't flower in time.
Well, that's pretty much the case with MOST varieties of tropical crop plants; your main impediment isn't the heat, it's that their photoperiod doesn't induce them to flower until it is too cold for them to survive outside. If that wasn't the case, I wouldn't have to devote a major pot each year to working out what hyacinth beans types will actually PRODUCE this far north. (so far I have only found two, Ruby Moon and the bushy one
@Zeedman gave me. I think there is a third as well.) And I'd be able to grow things like wingbeans with no problem. I'd have seed from my Egyptian River Hemp, Sunn Hemp and Kenaf (I DO have seed from my Kenaf, but only because I was able to take it inside over the winter and hand pollinate it.)
I know you can "fake" some of these plants with strategic use of covers and timing, but, usually, it isn't worth the effort versus what I would get.
I can't even ask the person I got them from if they will since not only will he not know, he might actually get cross I am trying to get calyces. When I asked him what the tea was like from this one (i.e. how it tastes without the anthocyanins) he threw a fit and said that this was was only used for its leaves for soup greens, not for the drink. And he doesn't exactly have an incentive to help me produce seed of my own (since it is in his interest for me to have to buy more of the seed next season.)
They sure were pretty plants though and I've thought to grow them many times since, it's one of my favourite herbal teas, too bad it needs sugar to bring the flavor out. My plants were not that big, maybe 4 feet, but the flowers looked just like Jing Orange okra flowers. Beautiful.
Same thing with a lot of my plants. I don't tray to grow those pseudo-hemps for fiber production; I'd never be able to grow enough to use anyway. I grow them for the flowers, Kenaf look like Hibiscus (which they technically are) River hemp have nice yellow legume flowers with black speckles on the back of the petals, and Sunn also has big yellow flowers (I DID get the Sunn to flower inside the house, but since pollinating it needs either an insect or knowing how to do that pea flower "tripping" trick (which I can't do) I got no seeds (then again, if I had, it probably would have driven everyone crazy until I took them off, there's a reason members of the genus
Crotalaria are called "rattleboxes".)
I hadn't thought of that Alasgun, I should give it a try. Thus far, I have not been super crazy about the type of sweetness stevia plants supply but I do like roselle tea so much that I think I'd give anything a try to be able to drink it more often.
I imagine it will. I use stevia instead of sugar in pretty much everything, and it usually does ok (though there is a bitter taste if I add too much.) I think the trick is stevia works best in strongly flavored things, where any aftertaste is drowned out.
If I doesn't there are two other "natural" zero calorie sweeteners you might want to try. The first is monkfruit, which works pretty much like stevia (just don't try and grow your own, not only is the cucurbit that makes it tropical and hard to grow here, but, based on the dried ones I bought in Chinatown before I really knew what it was, without processing it smells, and probably tastes rather like chicken soup (not a great combo with sweetness).
The second, newer one is called allulose. This is the closest to normal table sugar in properties (you can even bake with it the same as sugar with no problems). But it does ten to be fairly expensive (I got my supply cheap, but that's because I found it at a clearance store that must have gotten it from somewhere going out of business, so that line is not a reliable source.)
