@vonny,
It grew fine in my area of Los Angeles, in the sometimes having coastal fog belt - I did put it in the ground, semi shade, but watched it. Here in the land of hot or cold sand, I have it in a pot by the front door, somewhat sheltered. I did grow catmint in the ground, one 'shrub' lasting about three years until I killed it dead from water failure, there being mighty low rain here.
I left the apple mint roots and some sprigs and leaves. Don't know if that'll self resurrect in spring or not.
