Back in early September I discovered that we had Autumn Olives on the land and wrote about it. Since then they have ripened up a good bit so I've been eating several handfuls a day for the past couple weeks. I harvested about 1.5 pints of Autumn Olive berries in about 5 minutes from one bush, the largest I've found, which still has at least another 50 pints of berries on it. I'll be experimenting with different uses. They taste great and are highly nutritious.
Plants for a Future, an excellent plant database, has an entry for Autumn Olive.
