Symphytum asperrimum. Prickly comfrey; Comfrey. 
A coarse, rank-growing perennial herb, with purple flowers in nodding one-sided 
clusters, and large, rough leaves. A native of the Caucasus, which has been 
widely introduced and recommended as a forage plant for rich soils. It has been 
claimed that an enormous quantity of forage may be cut from an acre, but after 
extended trials in this country it has been determined to be of less value than the 
clovers, and is now rarely grown. It is propagated from the roots, which are set 
in rows 18 inches apart, and 16 inches in the rows. Its cultivation is not recom- 
mended, except when it is desired to procure an enormous bulk of forage from a 
small amount of very rich land. Prickly comfrey has proved a success only in 
New York, Michigan, and Florida, in the latter State having been recommended 
as a good forage plant for waste lands.
