Add to wishlist Remove from wishlist
This Lamiaceae species comes from woodlands in Japan such as Fukushima Prefecture. All summer you get to enjoy the subtly interesting leaf shape and texture, pondering what possessed you to grant this space in your overplanted garden. Once the riot of summer color is gone, the lavender spikes of this uncommon species brings clarity.
