lists as FAC+, meaning facultative; equally likely to occur in wetlands
or non-wetlands (estimated probability 34%-66%).
Stone (1911) says "This is a characteristic shrub of all the swamps of
the coastal plain. Its fragrance fills the air after the somewhat
similar odor of the swamp Magnolia of early summer has passed away,
while its handsome white flower spikes furnish a touch of color at a
time when few other shrubs are in bloom."
"At Manahawkin it is called Soap Bush, from the idea that the flowers
when rubbed together in water make a sort of soapy lather. Our results
have not been very startling, however."
Often found with blueberries and swamp azaelas.
Used in landscaping; flowers attracts bees, butterflies, and
hummingbirds; fruit attracts birds. Prefers acidic soil.
Clethra is the only genus in the family, Clethraceae, which is very
