@ai6yr When people ask me what tea herbs to grow, I steer them away from mint. You can pick it up for pennies at any grocery store and it's already in a teabag. No need to reinvent the wheel. Also no need to invite such a thuggish plant into your garden.
There are lots of herbs that make tasty tea and are easy to grow, but that are harder and more expensive to buy: catnip, lemon balm, bee balm, valerian, violets, clover, thyme, rosemary, lavender...
