Hedeoma reverchonii is a robust perennial with a woody base. It produces white or lavender colored flowers in the summer. The crushed plant has an odor of camphor or lemon. This trait helps distinguish Hedeoma reverchonii from the similar-looking Hedeoma drummondii, which is a smaller plant with an aroma of peppermint.[3]
