The peony (Paeonia) was adopted as the state flower by the 1957 General Assembly (Indiana Code 1-2-7). From 1931 to 1957 the zinnia was the state flower. The peony blooms the last of May and early June in various shades of red and pink and also in white; it occurs in single and double forms. No particular variety or color was designated by the General Assembly. It is cultivated widely throughout the state and is extremely popular for decorating gravesites for Memorial Day.
