Turtlehead is named for its pretty white blossoms, which resemble a turtle head poking out from its shell. It is an important host plant for butterflies, and its nectar also attracts bumblebees and ruby-throated hummingbirds. Turtlehead likes wet to moist soils and full to part sun. The plants have deep green foliage of lance-shaped leaves on upright stems and grow to 5 feet tall. They make a good choice for border and wet meadow plantings and will provide for a late summer bloom.
