The rose is a flower that grows on a perennial shrub of the genus Rosa, or that shrub itself. The leaves are pinnately compound, having pairs of leaflets along an axis with a single leaflet at the end. Many cultivated varieties have double flowers. Roses are used as ornamental plants in gardens and for cut flowers and rose oil. Roses come in many varieties and colors. Traditionally, red roses symbolize love and romance, white roses symbolize purity and innocence and are often used at weddings, and yellow roses are given for friendship.Red roses are often given on St. Valentine's Day as a symbol of love. The Rose was made the state flower of New York in 1955.   New York Consolidated Laws, State Law, Article 6, Section 75, adopted on April 20, 1955, states that:
§ 75. State flower. The rose shall be the official flower of the state in any color or combination of colors common to it. .
