Ceanothus americanus is a species of Ceanothus shrub native to North America. Common names include New Jersey tea, Jersey tea ceanothus, variations of red root (red-root; redroot), mountain sweet (mountain-sweet; mountainsweet), and wild snowball.
The red roots and root bark of New Jersey tea are used by Native Americans in North America for infections of the upper respiratory tract. The leaves have a fresh scent of wintergreen and were later utilized by the European colonizers as a tea substitute and stimulating caffeine-free beverage.
