How can I differentiate between spearmint and peppermint plants for identification purposes?

To differentiate between spearmint and peppermint plants, you can look at the leaves and their scent. Spearmint leaves are smooth and have a pointed tip, while peppermint leaves are slightly fuzzy and have a rounder tip. Additionally, spearmint has a milder, sweeter scent compared to the stronger, more menthol-like scent of peppermint.
