Comfrey, Symphytum 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 uplandicum in moist but well-drained soil in full sun. To propagate, divide plants in spring.

hello all , would this plant be suitable to plant in an allotment. ive read that its very good at nitrogen retention in the soil, placed in water for fertilizer and excellent in the compo at the end of the season, BUT ... would it grow out of control and self seed onto neighbours plots ?? thanks in advance for any replies
Have comfrey growing in my garden and harvest it as an activator for the compost heap.You can also rot the leaves down with rainwater which produces a black sludge that when diluted 15:1 is a great liquid feed
