Butterfly Pea —$10-20 — A strikingly attractive flowering vine. It is vigorous and fast growing, yet light of weight and easy to support. The flowers can be used to make a bright blue tea, which turns purple or pink when lemon is added. In fact, this tea can be mixed with lemon grass tea, which I also have (the non-smokeable grass, not the tea). This tea is an excellent way to add a psychedelic touch to your Downton Abbey viewing parties. Check out the YouTube videos (the Butterfly Pea videos, not the Downton Abbey videos).
