Where to get Comfrey?

[Alison]

I got some root cuttings last spring. Not enough to get a decent cut off it this year but I did find a really good crop near the canal which I plundered for feed.

Epsilon, it is just an unresearched opinion, but I fear that Comfrey will not survive in tropical climes.
The reason I think this is that most plants have proteins that work only within a certain range of temperatures; comfrey being a plant that originates from colder areas such as Siberia, I would be willing to bet (if I was a betting man) that it's proteins are skewed to work better at lower temperatures.

Thank you snohare, you are right. The gloxinia I have also shows sign of leaves shrinking when I bring it back to sea level land. It grew very well when I bought it in some high altitude area.

I think any other plants which produce flowers and leaves that can decompose easily may do the almost same thing as comfrey does.

The theory I keep coming across, is that comfrey is so good as a plant mulch/food because it has a long tap root and thus takes up nutrient minerals from deeper in the soil where most plants cannot access the leachate. So I would guess - again, just an unresearched opinion - that you want to try vigourous growing plants with deep roots.
Best of luck !

It wasn't B14 then.
I've been growing B14 for 5 years now, and I let it flower for the bees. It has never strayed from where I've planted it.
