While we’re on a theme of little-known North American natives, how about a shout out to Psoralea psoralioides…aka Sampson’s snakeroot. This delightful legume has prospered in our sunny garden for years, where it thrives, flowering over a month after it’s better known cousin, baptisia has finished. Psoralea is native from Illinois to the Gulf Coast, so it should be widely grown by now. Let’s have a show of hands…who has this in their garden? Raise your hands higher…I can’t see them.
Zone 6a-9b, at least.
