If anyone is interested in obtaining comfrey I will have some to trade as soon as we get our Spring thaw here ("here" is Minnesota, USA. Zone 4). Anticipate early April, possibly earlier, depends upon Mother Nature. I have some beds of very nice Bocking 14 comfrey which I have been growing for the past 9 years. I would like to trade starts for bamboo and/or kudzu. Yes, I know that kudzu is an invasive species in many areas, but here in the cold, frozen North it will not establish, even outdoors. In any event, my interest is in growing it in my greenhouse during the winter for fresh greens for my rabbits and guinea pigs, so it will never be outside here anyway. If interested, please message me. I know that it is early, but I do run out of starts most years, selling along with my herb and perennial starts, so best to make arrangements sooner rather than later. Cheers.
