Damp forests at medium elevation. Note by P.B. Pelser (30-Mar-18): Dichroa platyphylla is considered a synonym of Hydrangea febrifuga in some online databases, but J.V. LaFrankie (pers. comm., 6-Jun-16) considers it taxonomically distinct; the name Hydrangea platyphylla is occupied for a South American species, so if Dichroa platyphylla is indeed distinct, a nomen novum is needed.
