In southern California, there are a few seeds that assert themselves in late summer as things get drier. A lot of prickly, pointy things that stick to you or make themselves known in more painful ways.
A few of them were fun to play with as a kid. If you pick at the center of a dry burclover seedpod and pinch the end of it in your fingers, you can pull it away until all that’s left are a few seeds and one long coil of tiny spikes. Filaree seeds wind up tight to make a little drill when peeled away from the plant. And you can make foxtails travel on their own if you put your forearms together from wrist to elbow, hands facing up, and then have a friend place one on your wrists with the point facing you. Rub your forearms back and forth and it will travel down your arms.
But some seeds were just annoying. If you went for a walk through a field, chances are you’d come out with your socks and shoelaces absolutely covered in hedge parsley hitchhikers. Sandbur and puncturevine were the worst. Puncturevine has a few other nicknames. Goat’s Head, for the shape of the seed pod sections, and caltrop. It often grows on the dry, sandy areas near the beach making it particularly perilous for the bare-footed.
