Not for eating, comfrey is well known amongst gardeners for its ability to make a natural fertiliser by soaking the leaves in water for several weeks, sometimes called ‘comfrey tea’. What is less well know is the plant’s ability to produce beautiful purple flowers in late spring and early summer. However, comfrey is not really a decorate plant, and given its normal use, is best grown on an allotment rather than in a pot on the patio. The plant develops very deep roots and spreads, so growing in a large tub avoids unwanted growth.
