I know its not supposed to be "as invasive as mint" but I had one plant that almost became a shrub in a raised bed. Not too long after runners made their way into the yard, and we had Lemon Balm growing in the grass. Luckily we could keep it in check with the lawnmower. I'd put this one in a planter on the patio where it's fully contained. Nature finds a way.

I planted several of these in my garden beds. They have done wonderfully. Here in 6a, the lemon balm comes back every year bigger and more beautiful. I love it as a light summer tea. My kids just love breaking off leaves and crushing them for a wonderful scent. Lemon balm seems to be pretty well mannered for a mint!

Very prolific perennial. I winter sowed these.

This is great for teas. Will keep growing

The germination rate of these is amazing. I am hoping that I can have the time to harvest the abundance that resulted from just a few of the seeds from my packet! They smell AMAZING!
