This is a photo of a Toggenburg doeling in my pasture with comfrey and other plants. I use rotational grazing so they do not eat down the comfrey too much and weaken it.
For a comparison of Russian Comfrey Bocking #4 and #14 see the
the book "Comfrey Report: The Story of the World's Fastest Protein Builder and
Herbal Healer" by Lawrence D. Hills written in 1975:
"There are two commercial strains-- the Webster and the Stephenson.
The Webster Strain: This is the most popular commercial strain, started
by the late R. O. Webster to have been imported by his father from St. Petersburg,
Russia, in 1900. Bocking No. 4- This is the dominant in the strain,
about 50% to 60%. The flower color is Bishops Violet 34/3 when fully open.
It has strong stems and small wings."

leaves are broad and round tipped; their proportion is 5 to 10, but they
have no incurling: therefore they appear far wider than a No. 1, for example.
The edges are unserrated, and the veins are prominent, with bristles thickest
on the underside so that the upper leaf surface appears smooth. At leafy
stage these leaves are very large, recovering rapidly from cutting. The
stems, as in all variations under trial, are solid."
The photo to the left is of Lawrence Hills who
created all of the Bocking variations #1 through #21.
