I believe that catnip is of the mint family. I am familiar with mint because it grows profusely on the West Coast. But catnip, I have been looking for some seeds or plants already started so I can try my hand at growing some. Generally,I have a green thumb because whatever I put into the ground usually grows. One question; is it best to bring it inside during the winter months, or does it automatically sprout again when the weather warms up?
