Bambusa malingensis  
seabreeze bamboo  

There are two types of bamboo: "clumpers" and "runners;" we have only "clumpers" planted at Kona Kai, which are relatively slow in their expansion; only plant "runners" in your garden if you (and your neighbors) are ok with having your gardens replaced by bamboo forests in a surprisingly short period of time or you are prepared to implement some serious containment measures.
