Golden bamboo with a green culm and a yellow sulcus (groove). It has the same interesting distorted culms as the species. This is a form of Phyllostachys aurea and is not the same as Yellow Groove Bamboo. Opposite colored bamboo can be planted together for a very interesting effect; try mixing 'Flavescens Inversa' with the form, Phyllostachys aurea 'Koi'. We did such a planting in Portland's Chinese Garden.
This plant makes an excellent privacy screen, see Phyllostachys aurea for picture. This colorful form has the same growth habit as the original plant.
