Spearmint, Mentha spicata, produces dark green foliage with spear-like, serrated leaves and is considered one of the least spicy mint varieties but more robust than sweet mint. Its flavor, derived from the chemical compound carvone, offers a unique taste experience. On the other hand, sweet mint, Mentha x suavis, a close relative of peppermint, produces lighter-colored, rounder leaves and a flavor that's less cooling than peppermint but sweeter, inviting you to explore its unique flavor profile.
Both sweet mint and spearmint are not just versatile, but also incredibly popular among gardening enthusiasts. Their wide range of uses, catering to various culinary, aromatic, and even medicinal needs, makes them popular choices.
