Flowers

An excellent selection for a shady corner of the garden, wishbone flower gets its name from the pair of arching stamens at the center of each flower. A warm-season annual, it blooms from spring to frost with usually bicolored flowers in shades of blue, purple, pink, and burgundy. It grows just 8 to 12 inches tall and looks best when massed in groups of 10, 20, or more. It loves humidity.
