Confusion Risk

The following plants look similar and may be confused:

Japanese Stewartia Stewartia pseudocamellia

Closely related species with nearly identical showy white flower structure; Japanese Stewartia has distinct mottled peeling bark and serrated leaf edges, unlike the smooth-edged leaves of Stewartia ovata

Common Camellia Camellia japonica

Shares similar glossy dark green foliage and colorful blooms; Common Camellia has smaller, more rounded leaves and blooms earlier in the year than Mountain Camellia
