Indeed it is, especially up close! Cool! At one point in my life I was planning on becoming a botanist specializing in the woody bamboos, and I grew hundreds of species and varieties for a while. It's most likely some species of Phyllostachys, Semiarundinaria, Pleioblastus, Sasaella, or Sasa. If you send some photos (of the culms, branches, and culms sheathes), I could likely identify it. Indeed, the temperate runners can form vast forests, groves, and thickets! I know them well! 😁 🙏 💚 ✨ 🤙
