what is the difference between the bocking 4 and bocking 14 cultivars?
I am curious to learn more about comfrey used for livestock and land rehabilitation purposes. I grow True Comfrey, Symphytum officinale var patens, for medicinal use in my herb garden.
Next year I plan to plant a lot of comfrey in my pond and riparian areas for livestock and poultry use. Any info much appreciated.
The B-4 is supposed to produce more biomass, (and have a higher protein level than the B-14).
I've grown both, but never side by side, so I cannot either deny/confirm this.
I have heard claims that B-4 is hardier than B-14, but from what I've heard, all 3 are hardy to USDA Zone 3.
Personally, I don't see that much difference between the three unless...
...you are getting it strictly for medicinal purposes (in which case, get the true comfrey), or
...you don't want it to spread by seeds (in which case, get one of the Bockings).
As far as the question regarding International shipments, you may be limited to true comfrey. True comfrey sets viable seeds. International regulations are usually a little less restrictive for seeds than for live plants. And I would rather receive a packet of seeds that spent a month in the postal system than a live (?) plant.
The US, and Canada each have numerous vendors, and the UK has several (that's where the Bockings originated), so shipment within the EU shouldn't be too big of a problem.
Planted out 25+ crown cuttings of Bocking #4 Comfrey from Coe's Comfrey in NC (USA) -- within three days I have tiny shoots on the cuttings planted temporarily in pots. You'll have to ask if he ships internationally to your specific country -- every country has different export rules on receiving plants. I'm just so happy with these plants that I had to say something.

Exactly. Getting seeds across borders is one thing. Getting plants across borders without the proper paperwork is another thing altogether. One need only look at the US plant import regulations to get a sense of what is involved in moving plants across borders. Canada has similar type regulations. And the UK. All you have to do is google country plant imports and you'll likely find the import requirements for that country.
While a seller may be willing to sell plants anywhere around the world, he's very unlikely to be willing to do what he has to do in his country to satisfy the requirements of the destination country. Most countries require a phytosanitary certificate.
I never buy plants from outside Canada even if the seller is willing to sell them to me since I know that they will be seized at the border unless I get incredibly lucky.
