Devil's Claw (Proboscidea) Naturalization and Germination Challenges

Prince planted Devil's Claw and asks if it's naturalized and how to naturalize it.

Clarification (C.L.)

"Naturalized" means it spreads on its own; takes 3+ years to know. If that's not the question, clarify.

Note: Devil's Claw (Proboscidea louisianica) seeds are notoriously hard to germinate—dormancy adaptations. Some try freezing, scarification, or passing through animal gut. No confirmed data. Experiment and share results.
