With its tall straight manner, graceful leaves and ever changing green/blue-hued culms this is a stunning clumping bamboo. Gracilis is also an extremely fast grower to 5 to 6m and, with adequate moisture, will grow in a wide range of situations including coastal areas.
Gracilis can be used as a large screening plant for privacy against the double story next door or planted in a small courtyard as a specimen. This is one of the best varieties to manipulate to the form you want; keep it as a lush blanket of foliage, prune to the required height or cut and remove most of the culms for a minimalistic look. A ladder is not required to prune: simply grab hold of a culm at head height, pull it down and cut to the desired height, let it go, and it will spring up more vertical than before.
