What trumpet shaped flower is yellow and has spiky ball with seeds?

I don't think it is a Datura. I have Datura's.. .as does my neighbor. However, I too have a plant that has random almost Trumpet shaped flowers that are a pretty yellow and produce spiky round balls. My gardener suggested sweet gum, but I am not sure. I found this post looking for the same online.

This plant sounds like it could be an Datura stramonium.

This plant is toxic and can be brewed into a drink called Ayahuasca. The drink produces hallucinations as well as other affects. It can cause vomiting and in very rare cases, death.

Datura is also known as Jimson weed.

I too have one of these in my yard.

Do some research on the plant and its uses. It has long been a medical use for Asthma and many other sicknesses. People who drink the Ayahuasca describe the experience as life changing and mind altering.
