Does that mean "reborn"? Because that's exactly what this plant does every year. And it gets ten times as large as it was the previous year. See it growing by my window? I didn't plant it there, I planted it ten yards away. It sends out these half inch thick rope like runners that can travel at least ten to 30 feet away, depending on how strong the top growth was the year before. The top dies in the winter. Thankfully the runners grow shallow and are easy to pull.
