Ceanothus americanus is a species of shrub native to North America. Common names include New Jersey tea, Jersey tea ceanothus, variations of red root (red-root; redroot), and 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.^[3]

Description

Ceanothus americanus is a shrub growing between 18–42 inches high, having many thin branches. Its root system is thick with fibrous root hairs close to the surface, but with stout, burlish, woody roots that reach deep into the earth—root systems may grow very large in the wild, to compensate after repeated exposures to wildfires. White flowers grow in clumpy inflorescenses on lengthy, axillary peduncles. Fruits are dry, dehiscent, seed capsules.^[3]

Habitat

Ceanothus americanus is common on dry plains, prairies, or similar untreed areas, on soils that are sandy or rocky. It can often be located in forest clearings or verges, on banks or lakeshores, and on gentle slopes.^[3]

Distribution

Ceanothus americana is found in Canada, in Ontario and Quebec. In the U.S., it is found in Alabama; Arkansas; Connecticut; Delaware; northern and central Florida; Georgia; Illinois; Indiana; Iowa; Kansas; Louisiana; Maine (in Oxford and Penobscot counties); Maryland; Massachusetts; Michigan; Minnesota; Mississippi; Missouri; Nebraska; New Hampshire; New Jersey; New York; North and South Carolina; Ohio; Oklahoma; Pennsylvania; Rhode Island; eastern and central Texas; Vermont; West Virginia; Wisconsin; and Virginia^[4]

Ecology

During winter in the Ozarks of Missouri, its twigs are sought as food by the local deer; and White-tailed deer (Odocoileus virginianus), in particular, will browse C. americanus year round.^[3]

The flowers of C. americanus are used as food by (and the shoots host the larvae of) butterflies in the genus Celastrina, including Spring Azure, and Summer Azure; and by Erynnis martialis (the Mottled Duskywing)^[9] and Erynnis icelus (the Dreamy Duskywing).

C. americanus seeds are consumed by wild turkeys and quail.^[9]
