I'll do some research as an example of due diligence before I rush out and try the tea as it's used in herbal medicine. But this tropical vine grows a beautiful blue flower that makes a natural color changing food dye. They use it hot and cold in teas. E
It's naturally blue but mix in a acid like lemon or tonic water and you can watch as it changes color.
The plant itself is a nitrogen fixing vine that is commonly used to help restore soils. Between that and how marketable the dried flowers are I wonder if any of our tropical permaculurists are growing this.
I agree that they are beautiful and I really want to grow some to play with as a tea and natural food dye. I haven't had any success so far. 😢 I bought seeds from Baker's Creek last year and I scarified then and soaked them and they never germinated. I always save a few seeds just in case, so I have three seeds left to try again. I'm trying to find better info about how to geminate them. Those seeds were expensive!
Look! It's Leonardo da Vinci! And he brought a tiny ad!
