Phyllostachys vivax f. aureocaulis ‘Huangwenzhu’ is one of the more spectacular giant bamboos you can grow in the U.K it produces thick sturdy canes or culms as they are correctly known which can reach at least 8 metres high and be 7cm in diameter. The colour of the culms is predominately green randomly streaked shiny golden yellow, just to keep you one your toes occasionally golden culms are produced with the reverse green streaking. The leaves on this phyllostachys are relatively long and narrow being a deep lush green.
Collectively known amongst bamboo collectors as one of the giant timber bamboos Phyllostachys vivax f. aureocaulis ‘Huangwenzhu’ is best planted in a position of full sun to dappled shade in fertile moisture retentive but not waterlogged soil most importantly allowing space for it to grow into a magnificent specimen. In time it should be expected to develop in a grove formation often large enough to walk through the plant amongst to giant culms.
As with all giant timber bamboo like to thin my plants each year by completely removing old or thinner culms by sawing off at the base maintaining an open airy appearance. There is definitely something magical about walking through a mature bamboo plant, especially in a U.K garden resembling something you would find in the wilds of China or Japan. As with all big bamboo consider wisely when planting as these bamboos can and will spread, they are not what I’d class as running just big spreading plants so ideally consider a root barrier or some means of controlling them from visiting parts of the garden, you’d really rather they didn’t.
