Ask the Expert: Found this plant and trying to find out more
Hello! I am trying to find out more about this plant I found. It has these green round balls with small spikey things on them, but they are filled with air. Do you know anything like that? One of my friends thinks she has seen them dried before. She thought it was called an Oscar – but I keep doing online searches and can't come up with anything! THANKS! Michelle

It appears to be a Gomphocarpus physocarpus or Asclepias physocarpus. You friend was partially correct. There is a Asclepias physocarpus called Oscar. It is commonly called Ballon plant or Swan plant and is in the milkweed family. Catepillars love this plant. Although I don't think it is native any where in the U.S. (it is a southeast Africa native), there are many seed supplier who sell this plant. It can become invasive if not controlled.
