Johann's Garden

The following three variegated forms of comfrey all have this in common; the portions of their leaves lacking in chlorophyll are sensitive to sunburn if they do not have constant access to moisture during the summer and so will likely be best grown in very moist soil or in a location sheltered from direct mid-day sun during summer.  Additionally, none of these selections appear to have virally induced variegation, but rather appear to be a chimera variegation in that they contain a mix of both normal and albino tissue variously distributed through their above ground parts. Symphytum × uplandicum 'Axminster Gold'  I'm not sure the origin of this clone, but appears to be the only available variegated clone of Russian comfrey at this time.  The green portions of the foliage have a slight haze giving them an attractively silvery haze.  I don't see this in green leaf forms of comfrey so I suspect it may be possible that the surface cell layer is lacking chlorophyll even...
