Comfrey (also comphrey) is a common name for plants in the genus Symphytum.Comfrey species are important herbs in organic gardening. It is used as a fertilizer and as an herbal medicine.The most commonly used species is Russian comfrey Symphytum Ã uplandicum, which is a cross or hybrid of Symphytum officinale (Common Comfrey) and Symphytum asperum (Rough Comfrey).ature comfrey plants can be harvested up to four or five times a year. They are ready for cutting when about 60 cm (24 in) high, and, depending on seasonal conditions, this is usually in mid-Spring. Comfrey will rapidly regrow, and will be ready for further cutting about 5 weeks later.
Comfrey can also be grown indoors, in pots (1 to 5 gallon size) for a continuous harvest of fresh, small leaves. For this purpose best results are obtained by planting two-year or 3-to-4-year plants in the larger pots or 5- gallon buckets.omfrey can be planted spring, summer or fall, anytime the soil can be worked. In warmer climates, (Deep South and Southwest USA) it can be planted and the leaves harvested throughout the year. Comfrey grows best in USDA Hardiness Zones 3-9. But will grow almost anywhere.
