Whoops. I actually meant to say lemon balm, not lemon grass. Lemon balm grows well in the shade. Not sure about lemon grass but I do know that it's a good snake repellent.
Following! I plan to plant some mint and lemongrass around my chicken run to help deter predators and keep things smelling nice. Mine is in the shade in the woods...would love to try some shade loving flowers too.
