I mix a blend I call Garden Sani-tea because it is very calming. It has catnip, rose petals, spearmint and chamomile. I get the herbs from Mountain Rose Herbs. I also recently made a mix my husband calls Summer in Florida. It has orange mint, lemongrass, strawberry leaves and rooibos. One of my all time favorite tea isn't a blend. It's fresh chocolate mint.
It's easy to grow so if you have a moist area in partial shade you can grow all you want for the price of one plant.
