Screening Bamboo
In most cases the Bisset Bamboo is the best choice, closely followed by the Golden Crookstem.
Yellow Groove is also a good choice for screening especially in exposed conditions. Black bamboo works too, but not quite as effectively and as fast as the others mentioned.
The bundle is a great option if you have a larger area to cover.

Lower/Slower Bamboo
These Fargesia varieties are lovely bamboo in their own right and become very full bushy plants. But they are slow to grow and will take quite some years to become a significant size.
