Temple bamboo (Semiarundinaria fastuosa) in a group form develops as a tall, upright stand of closely aligned culms with a strong vertical emphasis. The culms are slender but firm, rising in parallel lines that create a striking, columnar mass. Leaves are relatively small and concentrated toward the upper sections, allowing the culms themselves to remain visually prominent.

Native to Japan, Semiarundinaria fastuosa is adapted to temperate climates and open woodland settings. Unlike clumping bamboos, it spreads through running rhizomes, though group forms often appear cohesive when established. A notable biological trait is its pronounced vertical habit and minimal lateral branching. The group form accentuates repetition and height, reinforcing the species’ formal, upright character.
