Mint is an herb that can be planted indoors, or outside as a perennial.  These will spread and take over, so if planting outside leave plenty of room.  They can also be planted outside in large containers if you want to contain them.   Mint is very easy to care for once established.  It can adapt to any soil or light conditions.  Leaves can be harvested while plant is growing.  For larger harvest, don't allow to flower.  If planted outside, transplant small stems into pot to keep in kitchen over the winter months.  Varieties: spearmint, peppermint, chocolate, apple, pineapple, orange, strawberry.
