Iresine

Iresine herbstii

shrub

Iresine is a tender perennial shrub prized for its striking foliage in shades of deep red, burgundy, pink, and chartreuse, often with contrasting veining. It is commonly grown as a houseplant or annual bedding plant in cooler climates. The small, insignificant flowers are secondary to the ornamental leaves that provide year-round color.
