Hi Jay,
Looks great! Love the idea of tossing old seeds into the garden, either to break down for more organic matter or perhaps to bless you with a
volunteer.
This is from a foraging perspective but I have always valued
Smilax vines. The shoot tips are what is commonly foraged, but the young
roots of select species are edible and a few species even have edible fruit. That being said, the fruit is certainly not choice. They are quite vigorous and thorny species often considered weedy, so they might well as a pioneer species in your forest garden.
Hope this helps,
Eric S.
