Is this a Catnip? I couldn't resist the beautiful colors & flowers- it is doing great in a cinder block- I am trying to root a cutting, but it seems to be very stubborn!
Calimintha variegata
It is a very pretty plant. I will take a stab at this and say it is in the same family but is not catnip.
With those blooms, you should be able to harvest seed rather if you have no success with cuttings. Good luck!
HI!
I have this plant too, and I understand it to be a relative of the mints. Here's some info that I found:
