I planted some grapefruit mint I think was the variety. It had soft lavender colored flowers on it. I know that mint spreads crazy by roots, but I figure I can keep it chopped out. But it later occurred to me that it may make seed that could come up all over the place? If that's the case, I may have to dig it up and put it in a pot more contained at cut off the blooms before they mature to seed.
