Being very hardy, this plant is well able to survive northern winters. Both the stems and leaves are softly hairy, the leaves have deep veining. The flowers themselves are a subtle pale creamy yellow, a significant characteristic for separating its identity from the purple flowered Russian Comfrey.
The plant does not need fertilization during the season, but responds well to the presence of organic matter.
A highly fertile soil with a clay structure is selected. But, in general, it is able to adapt to almost any quality soil and can do with much more modest conditions.
During the season, this plant can be mowed up to 5 times or even more, using the vegetative mass for livestock feed, for mulching plantings or for embedding in the ground during digging.
Since the plant is very unpretentious, it can withstand even very low temperatures, and it also tolerates heat easily.
Planted in open ground at the site. The plant is not demanding for the soil composition, but it will grow worse in acidified, heavy or excessively dry areas.
The rhizome of the plant, containing mucus, tannins and many other valuable components, which are widely used in folk and official medicine, has healing properties. Preparations based on comfrey root have an astringent, anti-inflammatory effect, have a hemostatic effect and many other healing properties.
