The Pleioblastus pygmaeus is an evergreen herbaceous plant, native to Asia; it is also called arundinaria pygmea, or Sasa pygmea. The radical apparatus of the dwarf bamboo is rhizomatous, which tends to widen over the years, with a ground cover; from each rhizome develop thin green canes, at most 80-100 cm high, semi-woody, which bear long leaves with a paper-like, light green consistency, forming a round, very dense shrub. These varieties of dwarf bamboo they tolerate pruning very well, and are also used as bonsai, or to cover large areas of land, frequently pruning them to a height of 25-30 centimeters. Sometimes dwarf bonsai are also used in a container, in an apartment.

Pleioblastus pygmaeus or dwarf bamboo is grown in any garden soil, preferring fairly heavy soils that are not necessarily rich in organic matter.
