Phyllostachys aurea ‘Koi'
Phyllostachys aurea ‘Koi’, Phyllostachys aurea 'Koi' is a gorgeous, golden running bamboo with green stripes, offering a more colorful and decorative alternative to standard Golden Bamboo — but needs management if planted in open ground.
The name 'Koi' comes from the Japanese koi fish, known for their brilliant colors and striped patterns, which mirrors the beautiful striping on the bamboo's culms.
