Bamboo (Bambusa)

*Bambusa* is a genus of woody bamboos, not a single garden cultivar. Kew describes the genus as native from tropical and subtropical Asia to northern Australia, with hollow, jointed culms and many species ([Kew Plants of the World Online](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:331143-2/general-information)). The current broad size and hardiness ranges are retained because mature height, spread, and cold tolerance depend strongly on the species and growing conditions. ### Growth and placement Many cultivated *Bambusa* species form clumps, but the genus-level label does not identify which species is intended. University of Georgia Extension documents several clumping *Bambusa* species with markedly different mature heights and cold tolerances, and recommends choosing a species suited to the local climate ([UGA Cooperative Extension](https://fieldreport.caes.uga.edu/publications/B1357/growing-bamboo-in-georgia/)). Confirm the species before selecting a permanent site or estimating the size of a screen. ### Water and establishment Bamboo needs regular water while establishing. UGA Extension recommends watering through the first several months and notes that species vary in drought tolerance; established plants still need supplemental water during dry weather. ## Maintenance Remove dead or damaged culms at ground level and manage the planting according to its identified species and available space. Do not assume a genus-level record guarantees a particular clumping pattern, final size, or cold-hardiness limit. The 2025 Yavapai County guide lists Bambusa at genus scope among fire-prone plants. This is a fire-hazard warning, not an individual assessment of every species or cultivar. Follow the guide's placement and maintenance guidance. ## Yavapai County — 2025 source scope and care The [University of Arizona Yavapai County bulletin](https://extension.arizona.edu/sites/default/files/2025-03/FirewisePlants3-14-2025.pdf), page 3, lists Bamboo with the botanical cell Bambusa sp. and form G. It places this entry in its fire-prone list. The matched catalog name is Bambusa. Source form codes: C=groundcover, G=grass, P=perennial, S=shrub, T=tree and V=vine. Printed names and form codes can include source spelling errors or historical taxonomic treatments; the source wording is retained separately from the catalog name and plant-specific habit. The bulletin warns that fire-prone plants can ignite readily and burn intensely, and should be removed or aggressively maintained when near a home, road or driveway. For native trees it calls for removing dead material, keeping limbs out of the lower 6–10 feet and clearing shrubs beneath the canopy. For other fire-prone natives it calls for isolated stands more than 30 feet from structures. Apply current local requirements and pruning suited to the identified plant. No plant is fireproof. Keep this Yavapai classification separate from Arizona UA, Utah, New Mexico, Idaho, Colorado and other source ratings and their placement, moisture and maintenance conditions.
