Chestnuts, acorns, mushrooms hopefully. Where I live, Echium is coming up for green leaves, Malva as well. If I don't get to picking Crataegus fruit now I'll do it later, but it starts turning black in the rain.
Late autumn is walnuts. My biggest foraging season. I have to pick enough to use it all year around. This year, I want to try to harvest some winter fruit such as sloe or rose hip.
I haven't done it myself, but I've heard of some plants that can still be foraged into the winter. Wintergreen is one, and apparently hackberries tend to stay on the trees for a while, even with snow on the ground. I think there's some mushrooms that grow later in the season as well.
Hmm whatever I can find. But likely pecans, persimmons, minerβs lettuce and chanterelles for sure. Those are some of my favorites. Other things probably just if I feel the urge and they are around.
But it doesnβt get too cold in my area so winter isnβt as much of a lull as it is in some colder places. Our winter is more like late fall or early spring in a temperate climate.
