You would probably have to keep it indoors or in a green house in zone 5. Mexicans and Texicans use it as a tarragon substitute. We often have trouble growing French tarragon down here and use the Mex. mint as a substitute. It has a much stronger flavor. Also makes an excellent tea. Likes well drained soil and full sun but does well in high shade also.
