Our goal is to harvest and dry the largest quantity of herbs we've ever attempted. We're using up the tail ends of many of our personal dried herb supply to be certain we have containers, space and motivation to follow through!
The rabbits have been enjoying tree greens we segregated from the the mulch and comfrey tops are a special treat as well. Comfrey used to be a common and highly sought fodder plant in cow fields. I believe we have a Russian Hybrid more common today. It doesn't spread by seed, but by division only. I'd love to find the true variety, but have yet to learn of a source. (Anyone who knows, please pass the info. our way! Or if you have some, would you be willing to trade?)
One down side we've learned to watch for; they are like velcro (where's that trademark sign?) to an angora coat! Avoid leaving fresh comfrey in your rabbit's cage/hutch or running area. They should be suspended or hand fed so they can carefully nibble without acquiring a new, nearly impossible to remove, wardrobe! They can be a challenge with your sheep too, but I've found mine tend to eat any remains right off of each other - not a tidbit wasted!
The hay appeareth, and the tender grass sheweth itself, and herbs of the mountains are gathered. Proverbs 27:25
