Amy notes that "catnip makes a good choice if you want a relaxing blend" in a tea. You can also draw wildlife to your landscaping by growing catnip (or many of the other types of catmint plants), including butterflies.
Catmint (Nepeta) is a member of the mint family. It is an extremely easy growing plant with few pests or problems. The billowing foliage is topped with spikes of flowers in early summer with repeat blooms throughout the season.
