When
I allow part of my yard to dry out, as when the city was putting in new
curbs and walks, the puncture vine is likely to show
up.
It is common in dusty fields, along dirt paths. The flower
is small, but bright.
If
allowed to grow, as in a vacant lot, the puncture vine spreads flat
over a diameter of 5 feet or so.
This
is the fruit of the puncture vine. When it matures it becomes
hard and woody. The spikes on it stick in the sole of
a shoe just like a tack. The vine earned its name from many
flattened bicycle tires. It's hard on bare feet as well.
