What pepper is this?

[Grunewald]

Grow many types of pepper plants over the years, and can remember what they all look like. But this one came up wild, nothing that I recognize, few plants growing under tree and fence line, obviously planted by birds. Think maybe from seed from a hybrid? Does have medimun heat.

Chili pequin, from what. I've heard, they are known to grow wild in Texas.

Not chilitepin. Have dozens of them on property, planted by birds. This is chilitepin photos in my front yard.
