This plant’s cool-looking flowers fascinate me, and make for easy identification. Buttonbush
is a North American native. It is found in wet areas such as lakeshores and habitats that are at least sometimes flooded,
including swamps, river edges, and the Everglades.
Plants: This deciduous shrub is 3-9½' (1-3 m) high, rarely reaching
20' (6 m). with many dense branches.
Leaves: Glossy, dark green, opposite or in groups of three, and up to 8" (20 cm) long. Flowers begin life as bumpy light green balls about ¾" (2 cm) in diameter.
Flowers: Buttonbush flowers look so unusual at every stage of
development, and are visible during so much of the summer, that this alone is usually enough to identify the plant.
Minute horn-shaped white or pale yellow flowers cover the surface, extending tiny sepal-bearing pistils. The flowerheads look like perfectly spherical softly bristled cream-colored balls up to 1¼" (3.5 cm) around,
each on a long stem (petiole).
the flowers age, they form hard brown seed balls—clusters of achenes—that look like bumpy brown cherries.
Edibility: Poisonous This shrub is poisonous to livestock.
