Symphytum officinale is a hardy, drought tolerant plant that prefers well drained soil and full sun to partial shade. As part of the Boraginaceae family, it is a course and clumping herb comprised of multiple stalks. Fresh comfrey leaves and roots are traditionally harvested and used in making topical preparations.
Comfrey can grow up to three feet tall and is characterized by large, hairy, oval-shaped leaves, and dropping clusters of pink to purple bell-shaped flowers. Comfrey flowers bloom from spring to summer and attract many bees with their nectar. Once planted, it can be difficult to remove as its roots dig deep enough into the ground that even a tiny portion left behind may sprout the following spring.
Seeds are very easy to grow. It is recommended to directly sown about three weeks before the last frost and seeds will sprout within a few weeks. Comfrey is an extremely cold tolerant perennial that will go dormant in the winter to later reemerge every spring. It can also be propagated by root cuttings or division.
