|can you by peppermint plants that can be used for fresh teas?|
|Yes. There are a number of mints (Mentha) that can be used in tea. Species such as Peppermint (Mentha piperita vulgaris), spearmint (Mentha spicata), and apple mint (Mentha suaveolens) as well as named cultivars are all fine to use as a garnish or as the base for a mint tea either fresh or dried.
Look in the herb department at your local retailer, or check a catalog supplier such as Richters. Their catalog lists many different mints under the alphabetical category M and click on "Mint Varieties"
Keep in mind that mint spreads aggressively and can become a pest in the garden. Plant it in a location where it will be contained by a building or walk, or consider planting it in a container.
