美洲茶也读了一下，它的生长范围没有包括加州在内呢？
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.[2][4] New Jersey tea was a name coined during the American Revolution, because its leaves were used as a substitute for imported tea.[
