This is the commonest and most abundant of all the wild Roses. It grows branching and bushy, from six inches to six feet in height, and has very slender, straight, light brown thorns at the base of the leaf stem, where they are generally set in pairs. Usually five rather thin, oval or sharply pointed, sometimes shining, and irregularly toothed leaflets form the compound leaf. The leaf-stem is guarded at the base with a pair of narrow, flaring wings that clasp the stalk. The numerous, fragrant pink flowers are usually solitary, and are two or three inches broad. Five prettily curved, heart-shaped petals are exquisitely set off with a circle of numerous yellow stamens, which are gathered around the darker centre of clustered pistils. The calyx has five long, spreading green divisions, the outer ones of which are always more or less lobed. In New Jersey and Pennsylvania, a charming double - flowered variety occurs. The Pasture Rose often grows in great, tangled masses, and when at the height of bloom these are exceedingly beautiful. This Rose is partial to dry, rocky soil, and blossoms from May to July, from Nova Scotia to Florida and west to Minnesota, Missouri, Oklahoma, and Louisiana.
