Ever eat a pine tree? Many parts are edible.
I planted a small patch of asparagus and it takes about 5 years to get a good eating asparagus. One year I decide to mulch it because of the weeds. Don’t ever do that, it killed all the plants, but one of my neighbors on the farm used to ride the back roads when it went to seed and would dig it up...When they go to seed, they are about 3-4 foot tall and are easily spotted along the sides of the road and you dig up a mature plant....If you have ever seen the house plant asparagus fern it looks just like that with some red berries on it....only a lot bigger...and tasty..It will keep bearing fruit as long as you cut it off at the base....it goes to seed if not cut.
