Additional Information at NatureServe

Diagnostic Characteristics:
This shrub is up to 3 ft tall. Ceanothus herbaceous differs from Ceanothus americanus (the more common New Jersey tea) in that the marginal veins begin several mm above the base of the blade (rather than from the base). The leaves are lanceolate not ovate. The inflorescence, an umbel, arises at the end of the current years growth whereas C. americanus has them on long axillary peduncles.

Disturbance of surrounding areas (particularly the slopes above the floodplain terrace) such as ATV trails, timber removal or any activity that results in increased erosion and weed invasion will be detrimental. Changes in the hydrology of the stream system where this species occurs would be detrimental.
