New Jersey Tea (Ceanothus americanus), is a shrub native to the eastern half of the US and Canda. It prefers dry open habitats and clearings on sandy and rocky soil. The name actually comes from the American Revolution when it was used as a substitute tea. It is a host plant for butterflies such as the spring azure, summer azure, duskywing, and dreamy duskywing. It is prone to deer browse, so beware if you live in one of those areas.
