I’ve seen balloon plants (Gomphocarpus physocarpus) in local pastures before, but not up close like this. The balloons are the fruit of the plants. The long hairy spines become stiffer and spiky-looking when the balloons inflate prior to releasing their seeds.

An intriguing plant. Poisonous? Oh toxic – just saw the comment above.

According to Wikipedia, ‘The leaves and stems produce milky latex that is toxic.’ But the plants does have medicinal uses.

Yes, I think there’s a few different balloon plants. This one has little white flowers.
