Since Bambu Batu first opened in 2006, a lot of people have come in asking, “What’s a Batu?” Now we also call the shop the “House of Bamboo”, so a lot of people have guessed that Batu means House. And a lot of people try to spell it Bamboo Batu. I’m sorry to point it out, but I’m afraid they’re both wrong. 

What’s the meaning of Bambu Batu?

Bambu Batu is one of the vernacular nick names for the bamboo species known as Dendrocalamus strictus. The term actually comes from Malay, an Indonesian language spoken by nearly 300 million people. In English, the species is more commonly referred to as Male Bamboo, Solid Bamboo, or Calcutta Bamboo. The plant is native to Indonesia and Southeast Asia, and it’s one of a handful of tropical varieties referred to as Iron Bamboo, having solid or nearly solid culms.

In Malay, the word Batu by itself means rock. So the literal translation of the name would be something like Rock Bamboo or Stony Bamboo. The fact is, this particular variety of bamboo is extremely hard and resilient to cracking. And oftentimes, the culms are solid, or very nearly solid, rather than being completely hollow like most types of bamboo that we are familiar with.

For all of these reasons, Dendrocalamus strictus is a top choice as a construction material and for building furniture. It also seems like a solid foundation on which to build a business. “And upon this rock I build my house.” Last but not least, the name Bambu Batu just rolls off the tongue so nicely. It’s pretty much impossible to say it without cracking a smile. Go ahead, try it!

What else do we know about this exotic variety of bamboo that’s so much fun to pronounce?

Growing to heights of 60 feet or more, with canes up to 5″ in diameter, Bambu Batu is a giant clumping species. This massive, tropical timber bamboo is native to Asia and the Indonesian archipelago. It is widespread in India, and today farmers cultivate D. strictus throughout the tropical world, in regions as disparate as Madagascar, Central America, Brazil and Cuba.

Young shoots are powdery bluish in color, but gradually turn green and then dark yellow or brown as they mature. Because of its formidable girth and unusually thick culm walls, this bamboo is considered a supreme variety for all manner of building, including light crafts, furniture and heavy construction

Pros and cons of growing D. strictus

For a short time, it was a dream of mine to grow some Bambu Batu in my backyard. While many varieties of bamboo grow commonly throughout California and are widely available in nurseries, Dendrocalamus strictus remains pretty difficult to come by, even from large online bamboo dealers.

I suppose it would be different if I lived in Vietnam or maybe Colombia, but California is not the right climate for this species. Like all species of Dendrocalamus, this bamboo is native to the tropics, and that’s really where it belongs.

Furthermore, despite its impressive size, and the fact that it’s a clumper rather than a runner, Bambu Batu just doesn’t seem to be the most desirable strain. This massive bamboo is not nearly as attractive as some other timber varieties, like Bambusa oldhamii or Phyllostachys bambusoides, for example.

Two important criteria to consider when assessing the beauty of a bamboo species are the shape and color of its culms. Yes, D. strictus is a giant bamboo, and that can be very desirable. But other characteristics make it less desirable. Rather than smooth, elegant canes with a bright golden hue or eye-catching stripes, Bambu Batu culms are thick and thorny with a web of interlacing, lateral branches that make the grove impenetrable. Moreover, the fat stems have a dark green — and what you might even describe as a dirty brown — coloration.

An interesting species for a bamboo connoisseur’s collection, but this is not exactly a prize-winning specimen for the well groomed garden.

Conclusions

Despite the affinity I feel for Bambu Batu, and the tremendous joy I get from uttering its name, I realized it just wasn’t the best choice for my landscaping. It requires a tropical climate that I cannot provide, and produces a thorny thicket I can’t fully appreciate. So in the end, I put the idea to rest. And instead, I settled for several other species that were much happier to be growing on California’s Central Coast.

Finally, if you’re planning to build a House of Bamboo, the Bambu Batu might be your best bet. But if you’re looking to plant a garden, you might want to think twice. And if you’re not in Indonesia, just remember to ask for it by name, Dendrocalamus strictus
