I'd thought the same thing. I think it's the extra nitrogen in the leaves.
Same as for comfrey. Also maybe some plants break down better than others.
I've used comfrey, but the plants seem prone to rust in out garden, so
have moved to nettles. It's also claimed that nettles and comfrey have
deep roots that bring up nutrients from the sub soils etc.

Genuine question are there any other plants that can be used too?
What about other deep rooted plants like docks, dandelion, horseradish?
