I like growing mint. For one thing, it’s easy. For another, many varieties are available, some of which you would otherwise be hard pressed to find. Here we see Vietnamese mint, Spearmint, Mojito mint, and Peppermint.
These are all different species in the Mentha genus (part of the large Lamiaceae family, which includes such herbs as basil, rosemary, sage, oregano, and catnip). Plants in the this genus have opposite leaves and square stems. And they are highly aromatic. (Mint oil is sometimes used as an insecticide.)
All of these mints began as small plants from Richter’s Herbs, based in Goodwood, Ontario. Mint tends not to come true from seed. Richter’s says that peppermint flowers in particular are sterile, so that true peppermint cannot be grown from seed at all. Best to start with seedlings rather than seeds.
