The leaflets are lanceolate or ovate-lanceolate in shape, covered with soft hairs on both surfaces, and have serrated to doubly serrate margins. Their bases range from broadly cuneate to rounded, and the tips are pointed. The leaves feature irregularly placed stalked glands and small prickles, distinguishing them from other species.

The flowers of hirsute raspberry bloom between April and July, measuring 1 to 2 inches (2.5 to 5 cm) in diameter. They possess a delicate arrangement of five white petals, creating a simple and elegant star-shaped form. These blossoms are occasionally accompanied by a subtle, sweet fragrance. The stamens are numerous and noticeable, radiating from the center of the flower, encircling the pistil. This characteristic structure and blooming period are vital for identifying this particular plant.

Hirsute raspberry features stems that are reddish brown or brown in color and terete (cylindrical in shape). The surface is covered with soft hairs and bears stalked glands.
