Valeriana ceratophylla is a perennial plant that can grow 31 to 60 centimeters (12 to 24 in) tall, but usually not taller than 50 cm (20 in). It grows from a taproot that is round at the top and taping downwards like a turnip to somewhat tapering at the top and often forking. The root can be as much as 20 cm (7.9 in) thick, but more usually is less than 10 cm (3.9 in). The caudex is 2–4 cm long and covered in the remains of leaf bases from past years and the brown stems of the present season. Most of its leaves are basal leaves, springing directly from the base of the plant, with only occasional leaves on the stems. They are twice divided pinnate leaves like that of a fern. They are attached by leaf stems that measures 1–7 cm long while the blade of the leaf is 8–21.5 cm (3.1–8.5 in) long and 2–3.5 cm (0.8–1.4 in) wide. The fused flower petals are form a bell shape about 5 millimeters long. They are white to somewhat pink in color and have silky hairs in the throat of the flower. It can flower as early as June or as late as September.
