I wasn't paying much attention, but I suspect they started out as a winter-sowing effort in December in a little raised bed beside my pond that I thought was a failure. I'd dumped all the potting soil out of the milk carton containers into the bed after some of the containers sprouted in a warm spell, then died. I wound up with a number of milkweed plants sprouting in the spring that I moved to the edge of my forest garden area, and then after I had dug those out, the horsemint came up and just took off. It's got a bigger-than-pencil-thick trunk on it now. Fast growth, once it started. I'm going to move it somewhere better once it gets cooler here.
I have the best success with things when I just throw stuff out there and see what comes up, it seems.
