This is sooooooo interesting; thanks so much for including the history with your photo. I think it is fascinating how plants were introduced from one place to another and the consequences that have happened ever since. In this country Kudzu was introduced to stableize the soil and it has gotten out of control and covers acre after acre after acres times tens of thousands of acres down South. Some people say that kudzu is "eating" up the South.
It's interesting to think how this one plant popped up in this isolated spot. A seed dropped by a low-flying bird? For what ever reason, it took hold and now stands firm, I'm guessing for many years.
