Comfrey and wormwood plants are specialty plants, they are not available in majority of nursery here, only specialty nursery and even they only have it once in awhile, not a stock plants.
I read that they are great for chickens. It took me a long time to get these plants and comfrey like a delicate plants, often died off and I potted a few so I still have 2 in a pots.
Wormwood plant I had survived, but it does not do so well, seem to delicate, but on the internet these plants are all glory and enduring.
What did I do wrong? Thank you for any advice.
