Symphytum x uplandicum

Russian comfrey, Symphytum x uplandicum, is a low-maintenance, weed-smothering ground cover plant that is tolerant of poor soil and neglect, and is particularly useful for wild or woodland gardens, or under trees and shrubs. However it can become rather invasive. It has plain green foliage and, in spring, short stems of red buds open to clusters of nodding purple flowers held just above the leaves. The slightly coarse bristly foliage is useful for putting onto the compost heap when cleared at the end of the season, and may also be made into comfrey liquid fertiliser.

Grow Symphytum x uplandicum in moist but well-drained soil in full sun. To propagate, divide plants in spring. Symphytum x uplandicum contains toxic chemicals called pyrrolizidine alkaloids that can cause serious disease including liver damage.
