Symphytum asperum, commonly known as rough comfrey, is a robust perennial wildflower native to the Caucasus region. It is distinguished by its coarse, bristly leaves and stout stems, which give the plant its species name asperum, meaning “rough.” The drooping, bell-shaped flowers are typically blue to violet and are rich in nectar. Unlike many comfreys, Symphytum asperum has an especially vigorous growth habit and readily spreads, a trait that led to its historical use as a fodder and medicinal plant but also to its reputation as a persistent species once established.
