A new variety of native North American bamboo was discovered this year (March 2007) by botanists in North Carolina. Hill Cane is the third known variety of this bamboo genus endemic to the continental United States. Arundinaria appalachiana, as botanists like to call it, differs from Switch Cane and River Cane, also native to the American southeast, in that it drops its leaves in the winter.
The global distribution of bamboo
Of the 1,400 or more species of bamboo, native groves of bamboo can be found five continents. It grows everywhere except Europe and Antarctica. The most diverse speciation of bamboo comes from Asia, but South America also has a surprising array of indigenous varieties. Many of the South American bamboos creep into Central America and Mexico. But once you cross the Rio Grande, the bamboo thins out pretty quickly.
In the last century, hundreds of species of bamboo from Asia and South America have been shipped around the world and naturalized in a vast range of habitats. Many of the temperate varieties of Chinese bamboo, especially from the genus Phyllostachys, grow very well in the United States and even into Canada. Mountain bamboo genera like Himalayacalamus and Fargesia also thrive in the cooler climates.
Characteristics and classification of Arundinaria
All three species of the genus Arundinaria come from the warmer parts of the Deep South, east of the Mississippi and south of the Ohio River. Prior to the arrival of Europeans and the establishment of large farms and plantations, these native grasses covered vast swaths of this region. But today it’s fairly scarce and something of a novelty.
These bamboos are especially cold tolerant, hardy down to temperatures well below 0º F. They are also more adaptable to wet soil conditions than other bamboos.
Not all botanists agree on the classification of the genus Arundinaria. Most authors only associate with three species: A. appalachinana, A. gigantea (River cane), and A. tecta (Switch cane). But until rather recently, the genus also included a handful of other species which have since been categorized as Thamnocalamus, Yushania, and others.
These unusual bamboos occupy sort of a gray area in bamboo taxonomy. They are very cold-hardy like temperate bamboo, of the tribe Arundinarieae. But they exhibit more of a slow-spreading growth habit, like tropical bamboos in the tribe Bambuseae.

Cultivating Arundinaria bamboo in your garden
Although interesting and native, A. appalachiana and its cousins are not prime choices for a decorative garden. They like the beauty and elegance typical of many ornamental bamboos. The culms are tall, often 20 feet or more, but somewhat thin and lanky, with leaves spread thin.
On the plus side, this species of native bamboo is cold-hardy down to around 10º below zero F. It’s also very tolerant of wet, saturated soil, something most bamboo cannot withstand. So if you live somewhere in the Southeast with cold winters and moist terrain, this might be your bamboo of choice.
Less of a specimen plant, these Arundinaria varieties look better in open areas, where they’re allowed to go native, if you will. If you have some rural acreage, you might look for some of these bamboo species.
But don’t expect to find any of these North American bamboo varieties at your local nursery. You might be able to get Arundinaria gigantea (River Cane) from a bamboo specialist. But it’s still a long shot.
