I think you are right. I looked at images on Google. I’d never have figured that out on my own!Sorghum, possibly?
There’s another plant on what I know is a local orchards land that I’m curious about. I think they are letting asparagus establish there by letting it get full grown. I could probably just ask them in their store but it’s one of their locations separate from their main store and orchards so they might not know either.
