Foraging

When L and I met we lived in a house bus for several years so didn't have a garden of our own. I grew herbs in planter boxes of course but we over came the lack of a garden by doing alot of foraging for food and firewood. There are still several spots I visit where I know good fruit and nut trees are growing wild. I usually say to L at this time of year "better go and check if my peach tree is ripe" and he knows exactly where I mean. I also have several walnuts to call on, along with mushroom circles, rose hip bushes, elderberries, wilding plums, apples and pears as well. A couple of years ago I found, with a little help of a friend where some hazel nuts are. The jewel in the crown though is the pine nut tree I think. My brother and I visited there last week filling our pockets with the little treasures.The kids will have to do some cracking for me so I can make a fresh batch of pesto with local ingredients. Both my brother and I have saved some seed to try and germinate as well. Our property is not big enough for one of these massive trees but I've had plenty of people offer to let me plant them on their land. I looked to see if the seeds need any kind of stratification but haven't found anything to suggest they do. Has anyone got any tips? I seem to have trouble raising trees from seed in pots but get plenty of walnuts, peaches and apricots coming up if I just throw the stones in the garden and ignore them til the following spring. I'd love it if people would come and dig them out of my garden and give them new homes, I have even thought I should go on a fruit tree planting mission in public places so others may benefit from the fruit.
If you like the idea of foraging, Johanna over at star-cooked has some good posts about it. The native flax seeds are one I'm keen to try.
