Arundo donax

Don’t be fooled by imitations. While there are several hundred (if not thousands) of species of Bamboo, there are also a handful of lookalikes to be aware of, and perhaps avoided. Last year we told you about that friendly desktop pot of Lucky Bamboo that you probably thought belonged to the Bamboo family. Don’t worry, we forgive you. It was an honest mistake. The folks at the hardware store just wouldn’t sell as many if they labeled them “Lucky Dracaena”.

Today we’d like to tell you about an invasive reed grass clogging the creek beds of southern California, and spreading vigorously. From a distance and to the untrained eye, it will look a lot like Bamboo, but it’s actually a Mediterranean import known as Arundo donax or giant cane, although it’s sometimes even referred to mistakenly as Arundo bamboo.

What is Arundo donax and why is it a problem? Aggressive growth habit: As you probably realize, or perhaps have even witnessed, many varieties of bamboo can also be very invasive. What starts as an ornamental accent or an oriental privacy hedge can spread into a horrible nuisance under the right (or wrong) conditions. This is what we call “sustainability in its unfriendliest form.” While it makes a beautiful addition to many domestic landscapes, Bamboo does require proper containment. This can be as cheap and simple as an old wine barrel, or as expensive and complicated as you want to make it. Otherwise it will spread and spread, generally in the direction of water, such as lawn sprinklers. Invasive species: Unlike Bamboo, Arundo donax is native to the Mediterranean. This means that California climate conditions are ideal, with or without the irrigation required by most species of Bamboo. It was brought over in the 1820 for erosion control in the Los Angeles area, and in the subsequent 190 years has established a tenacious foothold throughout the region, but especially in riverbeds. Predator resistance: As with most invasive, non-native species, Giant Cane has no real predators in this part of the world, so it continues to spread while choking out the native flora. Ideas for containment range from toxic chemical herbicides (not necessarily something we like to see sprayed around creeks and river beds) to the importation of natural predator insects from the other side of the globe (can you say “unanticipated environmental consequences”?). Toxicity: One reason that the Arundo donax is so resilient against local insects has to do with the high levels of noxious chemicals in its leaves and stems. As it so often happens in plant chemistry, many of these “toxic” chemicals also happen to be psychotropic alkaloids and tryptamine compounds. So while it may lack most of the industrial applications that Bamboo is known for, this giant reed grass may have certain pharmaceutical and/or recreational uses yet to be fully explored. Elegance and durability: The Giant Cane has historically been used for flute making and is also said to be an ideal material to make reeds for woodwind instruments. But, the canes are not nearly as hard and durable as Bamboo, but it does get very tall (upwards of 20 feet) with fairly thick canes (over 1″ in diameter). But despite its size and feasibility as a privacy screen, Arundo donax does not have nearly the same grace and elegance as a healthy stand of bamboo. Fire hazard: Highly flammable, the cane grass  has been known to increase the probability and intensity of wildfires. And what’s worse, it has a far better burn-recovery rate than any native species, so that when the landscape is decimated by fire, the canes sprout up first, leaving no room for the original natives to return or survive. Along with the factors listed above, these characteristics seem to make the Giant Cane’s invasive potential far worse than that of bamboo. Potential benefits of Arundo donax?

We’ll spelled out a litany of threats and detriments posed by this giant reed grass, but surely it must have some positive attributes? Yes, in fact, with increasing concern over climate change and greenhouse gasses, Arundo donax has been identified as having a relatively high capacity for converting carbon dioxide into oxygen (somewhat similar to bamboo) and for sequestering carbon in the soil. For this reason, it is sometimes planted as a cover crop and rotated between cereals and grains.

Also, on account of its carbon sequestration and its tenacious growth habit, giant cane grass is now be recognized as one of the most promising crops for bio-fuel and energy production in Europe. Several energy companies are currently working with Arundo donax and studying its potential more closely.

In the meantime, unless you’re planting a cover crop or using your backyard to produce bio-fuel, we encourage you to avoid the Arundo donax and plant some more attractive varieties of bamboo instead. But be careful, these grasses all tend to spread aggressively, and if you don’t take proper precautions, you too could find yourself on the wrong end of a sustainable revolution!

bamboo and lucky bamboo

It happens twice or thrice a week. A customer walks into the store with a look of determination on his or her face and asks if we actually sell just bamboo. Now, I have complete appreciation for a customer who knows what they want, but since this is an all-bamboo store, and virtually every item in here is bamboo, I usually just raise my eyebrows in expectation, waiting for a more specific request.

As often as not, when someone says they’re just looking for actual bamboo, it’s actually the plant commonly called Lucky Bamboo that they’re seeking. As it happens, however, this “lucky bamboo” is really a species of dracaena, and entirely unrelated to the vast sub-family of true bamboos. (See photo above for contrast.)

What is Lucky Bamboo?

Dracaena sanderiana resembles bamboo in appearance, but is actually a hardy houseplant that thrives in water (no soil needed) and requires little or no natural sunlight, making it perfect for offices, bathrooms, and other indoor settings. Its appearance and ultra low-maintenance are probably what earned it the name Lucky Bamboo. But as a member of the family Asparagaceae, this adorable houseplant is actually more closely related to asparagus than than to bamboo.

In the Orient, Dracaena sanderiana has long been revered as a great remedy for feng shui and a source of good luck. Maybe it’s the fact that it’s so darned easy to grow. Also, it can be trained and shaped nearly as easily as a balloon animal. It’s not clear how or when the idea came to be, but today Lucky Bamboo is placed in homes and businesses around the world as a of way of attracting prosperity and good fortune.

Another curious fact about this Oriental talisman, the Dracaena sanderiana is actually native to Africa. Although today, when you see markets, florists and boutiques selling Lucky Bamboo, these specimens are almost always imported from China or Taiwan. In many case, the stalks are shaped in to spirals or hearts, and sets in ornamental vases or pots resplendent with fortuitous iconography from the Far East.

So yes, in fact, it is quite lucky, but bamboo it’s not.

What is Bamboo?

The 1200+ varieties of true bamboo technically belong to the grass family, Poaceae. Among these 1200 or so strains (some say the actual number of bamboo species is closer to 2000), you will discover a great variation of appearance and growth habit. Bamboos do grow all across the globe, from the tropics to the Himalayas, with species indigenous to six continents. Generally, they prefer a lot of water, but there are even a few more drought tolerant varieties.

But despite that great diversity, there is a certain characteristic consistency that makes bamboo fairly recognizable. Everyone knows that bamboo grows up in shoots, mostly cylindrical, although there are a few more square-ish strains. The strikingly similarity between bamboos actually makes the different species very difficult to distinguish, particularly for the novice hobbyist gardener. At the same time, there are a handful of look-a-likes, including the Lucky Bamboo, that can be very easily mistaken for true bamboo.

Unlike Dracaena sanderiana however, bamboos do share the same general growth habit as all other grasses. That is, they require full or at least partial sun exposure, some type of soil medium, and should most certainly be grown outdoors. Lucky Bamboo, on the other hand, as mentioned above, thrives in dimly lit quarters with nothing but a vase of water.

Because Bambu Batu is located indoors, with one large, east-facing window, it’s fairly difficult to keep a true bamboo plant happy and healthy. We generally keep one specimen by the front door, where it gets good sun and plenty of fresh air, but I also rotate it with other potted bamboo specimens from my yard at home, so they are never stuck indoors for too long a stretch.

As for the Lucky Bamboo, yes, we do sell it. It is one of the 5 or 6 items at Bambu Batu not actually made from bamboo. LOL. But rest assured, if it’s not genuine bamboo, it’s definitely lucky. Prayers Bundles from our friend Renya are another perfect example; also our eco-friendly, non-paraffin candles made from soy and beeswax. So if you’re feeling lucky, or just needing a little more bamboo in your life, head on down to Bambu Batu. We’re always eager to exchange a few cultivation tips.
