- Description
-
Referring to the belief that comfrey helped to heal injuries, the scientific name Symphytum comes from the Greek words symphyo or grow together and phyton for plant. Together translating to a plant that heals injuries. It has a long history of use as a medicinal herb for topical and internal injuries, though it is no longer deemed as safe for consumption. It is said that the leaves and roots can be used to treat rashes, swelling, cuts and bruises.
One of the many plants called comfrey, this variety grows best in full sun to part shade and well-drained, moist, rich soil. In NC's hot summers, it appreciates some shade from the afternoon sun.
It is deer resistant and tolerant to drought and clay soil.
Its foliage is a good addition to a compost pile. It can be pruned several times a year and is often used as compost for food crops. A liquid fertilizer can be obtained by soaking the leaves in water for at least one week. The potassium from this plant is great for growing tomatoes.
As it easily spreads and will sprout from any root pieces left behind from removal, it can be grown in large containers to better control its spread. Its rapid spreading habit does make it a remarkable candidate for establishing an attractive colony.
Insects, Diseases, and Other Plant Problems: No serious insect or diseases issues. Snails and slugs may damage the foliage. Heavy rains can cause the leaves to droop.
