Bamboo for a balcony screen, which can be kept below 150cm?
To the left (out of shot) is a piece of glass which is the main privacy-compromise on my balcony, so I'd like a slim, oblong planter, with a tall plant that creates a natural screen, in keeping with the zen theme.
Tall grass was my initial idea, although it does get windy here.. and I'd like it to be all-year. Bamboo seems very sturdy and in-theme, but grows very fast?
Is there a species I can get which either grows to under 150cm, or could easily be pruned and kept at that height, most or all the year round? The roof on my balcony is around 2 metres; and I'd like to keep it low enough to took over (under 150cm).
Alternatives (eg Grass?) I will also consider! Anything that can form a screen at the appropriate height and has somewhat of a zen-theme..
