Definition
Trumpet weed can refer to several plants, often ones with trumpet-shaped flowers or those that spread aggressively. One example is Eutrochium fistulosum, a type of Joe-pye weed. Think of it as a catchy nickname for a plant with a distinctive shape or behavior. Some "trumpet weeds" are considered invasive due to their rapid growth. The term is more descriptive than scientific. The aggressive growing nature of some is why it has this nickname.
