I have a medium pot where I've been trying to raise a guava tree until it can be definitely placed. Then I've been out for 2 weeks and when I came back, there was an invasive plant spreading all around, coming from its pot and, since I already grow some basil and mint to use as seasoning, I've got interested about:
What plant is this? Is it edible? Does somebody knows how does it taste like? Could I use it as I use my basil, since both look equally harmless?
It may be useful to know I live on the very south of Brazil on a wet and rainy region and that it seems very happy on a very dry mix of organic compound and soil from an eucalyptus forest.
