fast growing bamboo info needed’

I woiuld like suggestions for two fast growing bamboo species. I have a small patio with an adequate raised bed at end. at one end of this i wish to put a reed screen in a semi-circle and two fast growing bamboos contained, in front, i wish to half secretly bury a beautiful contemplative buddha i have acquired much to my delight.I am a complete beginner, this is my first ever garden. it has no plants per se!
