Those multi-use herbs have extra bonus points! For instance, some combination of nectar plant/butterfly host plant/culinary use/herbal remedy etc.
I've been subscribing to The Herb Companion for a while and was disappointed to find out recently to find that the publisher was combining it with another magazine. Not that much herbs covered in the 2 issues I've seen since, so I cancelled my subscription. I might check a used bookstore and see if I can find old issues from before I subscribed. It was a great magazine, so what a shame!
