all manner of critters fit the bill. if that doesn't suit you, groundnut tubers (Apios americana) are pretty good at 17% crude protein. almonds are available grafted to dwarfing root stocks. honey locust (Gleditsia triacanthos) seeds contain up to 24% protein. Caraganas are an easily grown perennial source of protein. keep trying, I'm sure you'll find something that works for you.
Atriplex halimus, saltbush, is another shrub with tasty leaves. I haven't had any luck tracking down a plant or seeds in the United States (pronounced "yooo-nited"), but I've heard they're delicious. any suggestions?
I can vouch for tilia, have tried toona too, though not as much use for that one for me, since they are small.
Tilia is starting to become an important staple in my diet in spring-summer, and have plenty of coppiced sprouts growing all over the place, so I have plenty to eat of it. If I recall, I think I first saw it mentioned on pfaf.org as and edible. Very mild green that I can eat raw. http://www.youtube.com/watch?v=T35Snp-dffA midway shows my appreciation for Tilia
You call it Tilia here and bass wood on the video.. i type in Tilia and get a vacuum food sealing device... so bass wood comes up with 30 varieties... You must like it as in your video you seem to have quite a few growing... Is there a certain variety that you are growing?

Surprisingly the Mulberry tree(Morus spp.) what many know for its delecious edible fruits, also has leaves that can be used as a cooked green! I recently found this out during a conference and was absolutely stunned. The silkworms love em, they've gotta be good!? I have been unable to find any information regarding certain varieties for eating. However we could all start sampling the wild and cultivated types to find the best varieties!
If anyone has experience with these plants or has any information to add this would be greatly appreciated!
