Phyllostachys aurea ‘Koi’ is definitely one of my favourite bamboo it really is gorgeous with golden canes streaked alternatively between the nodes in deep green. Each cane holding masses pale green leaves to add to the beauty. It is also a ramrod striaght bamboo, large enough to be impressive but not too big to scare you off. For me Phyllostachys aurea ‘Koi’ makes a superb specimen and can even be used to make a very impressive screen or hedge.
Given it’s upright habit ‘Koi’ is perfect for adding height where space is limited and although it belongs to a family that can be invasive I’ve found ‘Koi’ to be pretty much clump forming rarely sending up canes far from the main plant. In my garden each year I prune of the sideshoots up to 1.20cm from each cane to show off the lovely cane colour and crowded nodes like its more commmon relative Phyllostachys aurea.
