Trees/or shrubs with edible leaves?

First off, Tilia cordata, Little Leaf Linden(  ((보리수·참피나무 무리)) ), or Lime(라임(레몬 비슷하게 생긴 작은 녹색 과일)) in the UK. This tree of many names supposedly has leaves that can be used as a salad/sandwich substitute for lettuce. Martin Crawford of the Agroforestry Research Trust is highly fond of these leaves, and coppices the trees on a rotation of 5+ years or so. Coppicing would ensure that the plant doesn't grow too tall so that there are plenty of leaves within reach. Linden also produces nectary rich flowers that provide bee fodder. There is evidence that other members of this genus also have edible leaves, such as Tilia americana- the native NA species. I do not know the quality of the wood but perhaps this could be a multi-purpose perennial leaf crop/timber product/ honey tree!?

Next, I would like to metion Toonia sinesis, or Fragrant Spring Tree. This has been a popular vegetable in Japan for a while. I have heard that the leaves have a smoked garlicly flavor that is quite strong; according to Eric Toensmeier, author of Perennial Vegetables, the leaves are too strong to be used as a main green, but more so as a flavoring herb in stir fries,etc. once again it could be coppiced on a rotation to prevent it from growing too large. As the name implies this is also a good ornamental with fragrance. There is a cultivar currently available called 'Flamingo' that may provide better leaves for eating.

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!

Last but not least, is Lycium barbarum, 구기자나무 or the Goji plant. This has been a popular healthful fruit in China for centuries. It recently gained interest in the Western world as an antioxidant rich 'superfood'. The dried fruits are absolutely delectable, and I have yet to try them fresh. What most people don't know is that the leaves of this tomato relative are of full edibility(cooked or fresh). I am unsure what the fruit yields are like, but this photo looks very promising: http://media.growsonyou.com/photos/products/26113.jpg
Perhaps this could be a productive berry and leaf crop? All of the growers I have talked to say it is extremely vigourous and hardy. I am propagating a bunch from seed right now(which is very very easy), so we should know more on this soon!!
