You can order loose green and black teas from Frontier Herb and Spice, as well as herbs and tea mixtures. Look for a coupon code. I've also gotten some deals off eBay. If you have a septic tank, grow your mint over the drain field. Only the roots touch the fertilizer. Or if you have a gutter drain or a hose bib which gets plenty of water, grow a mint variety there.
All of you hot-climate stretchers can grow Lemon Verbena, which tastes exactly like lemon drops and makes a great tea additive or stands well on its own. What I truly miss here are Mexican Tarragon--as many Latinos as we have here, still no-one sells it--mixed with Anise Hyssop. Instant root beer tea.
And sassafras digging time is here for most of you--when the days are warm and the nights are cold, but not freezing.
