Nice article, Rita. I found out that parsley is also good for goats. I was growing some and my son asked me if I had any more (I didn't). But this year I will grow a lot more. My son told me that parsley aids in digestion and is often included as part of herbal wormers for ruminant animals. I also read that parsley has also been credited with curing foot-rot in sheep and goats.
So I'll plant it for us, the butterflies and the goats!
