Episode Notes:
This month's episode features Pokeweed (Phytolacca americana). This is a fascinating plant with some surprising tie-ins with American history. Join Steve and Bill as they tell you about pokeweed's uncommon red pigment, its use in phytoremediation, and the various ways in which it demonstrates toxicity.
