English Ivy and bamboo unfortunately. Both creeping in from neighboring yards |
I have liriope, huechera, day lilies and none of them spread. This is my 3rd year.
My mint is spreading a little but I pull them quickly and keep it small. I’ve tried growing in a pot but they don’t get big leaves. My lemon balm, oregano also spread but I am able to keep it under control. |
We LOVE our mountain mint -- planted in the right area. It really does spread, but that's perfect for the margin of our property that is otherwise overrun with invasives. It is native and very beneficial for pollinators, so if you have a big enough area, it's a great choice. We are planting more mountain mint every year and hope for a meadow of it over there! |
It goes pretty deep and entwines itself in the roots of other plants. I have a large, very mature garden. To remove every plant and all the dirt down 3 feet or so would be ridiculously expensive and likely destroying very old specimen plants. |
