I planted a honeycrisp in my yard this spring and this started growing. It was neat looking so I let it go. It's about 5 ft tall, thick, and has purple flowers like pumpkins do with a large female and small male flowers. It grows these large spiked balls that haven't opened yet.
I'm trying to practice as much as I can. Hopefully, one day, I can be as good as @Native Hunter (I doubt that though). Jimson Weed is poisonous and has been used by some as a hallucinogenic to produce visions.
