Does anyone know of non-toxic plants? I want a fast growing vine with edible fruit (for humans) to grow on my chain link duck pen. It's partly for providing extra shade for the ducks but also because I plan on growing fruit vines anyway, so this'll save space. There will be a trellis as a separator to keep them from eating very many leaves. I think blackberry plants are non-toxic so I'll probably do a section with blackberries but I want some variety. I've considered...muscadine grapes, kiwi fruit, kiwano melon, cantaloupe/melon, passion fruit (but i think the leaves/flowers are toxic?), but I have no idea what plants are safe. There is so little info online about whether these leaves/flowers are toxic. While the fruit vines are growing in I could do veggies that vine like bean plants, squash, zucchini, cucumbers, etc but again, I'm not sure which plants are safe.
