Bamboo can serve many purposes in a garden setting. It’s a wonderful ornamental plant with abundant, green leaves and elegant, upright canes. Some types of bamboo make a good ground cover and some timber varieties are great to harvest for their massive poles. There are clumping bamboos that will stay fairly compact, and there are running varieties that can spread quickly. And some might even spread a little too quickly. One of the most popular reasons for planting bamboo is for a hedge or a privacy screen. So what are the best species of bamboo to plant for hedges?

Bamboo can make an excellent hedge or privacy screen with its stately height, dense foliage and fast growth rate. But different species of bamboo have different growth habits. When you select a bamboo species for your hedge, you’ll want to plant something that fills in quickly, has thick leaves, and grows to an appropriate height depending on your privacy needs. In this article, we’ll talk about what characteristics to look for and identify a handful of the best varieties for your bamboo privacy screen.

What to look for in a bamboo hedge or privacy screen

With more than 1,200 species to choose from, selecting the right type of bamboo is not always a simple undertaking. The conscientious gardener will have to evaluate their growing conditions and determine what sort of features they want from their bamboo. Then they have to go through the catalogs and species lists to find a bamboo variety that has all those desirable characteristics. So what are the properties of a good bamboo hedge or screen?

Growth rate

In most cases, when you plant a privacy screen, you want a plant that will grow quickly and fill in the gaps. The longer you have to wait for it to grow, the longer you will have to suffer without privacy. And whether you like to sunbathe au natural in your garden, or just host a lot of backyard barbecues, everyone enjoys a little privacy.

For this reason, the most popular bamboo screens tend to be the faster-growing running varieties of bamboo. Unlike the clumping types of bamboo, running bamboo can spread quickly to fill in an area. At the same time, you have to be careful that the running bamboo doesn’t “over run” your garden. In order to do this, you’ll want to place some kind of root barrier in the ground to confine the plant to a designated area. Another option is to keep the bamboo in large containers or planter boxes. Either way, containing the roots of the bamboo will make it far easier to keep the plant under control and maintain an attractive, hedge-like shape.

Some gardeners will prefer to plant a row of clumping bamboos and wait for them to fill out. If you don’t need to create a complete, uninterrupted screen, or if you’re not in a hurry for it to fill in, this can be a good option. Many would rather do this than have to contend with the tenacious rhizome roots of a running bamboo, two or three years down the road.

Size and shape

Some varieties of bamboo will only grow a few feet tall, and others can easily grow well over 50 feet. So there are bamboos that make a nice short hedge along a walkway, and then there are taller bamboos that provide privacy similar to a 6 or 8-foot fence. But if you want privacy all the way up to your second story bedroom window, there are other options. With bamboo, anything is possible!

The size and shape of the poles is also worth thinking about. For a tall privacy hedge, you’ll probably want a bamboo with straight, upright canes. Certain bamboo varieties have very interesting canes with irregular shapes and uneven patterns, but these are probably less desirable for a hedge. However, if you prune back the foliage on the lower few feet of the bamboo, the irregular culms can add some interest to the hedge.

You can also choose between slender canes (an inch or less in diameter) and thicker canes (3, 4 or 5 inches in diameter). This will mostly just be a matter of personal preference. Although, if you’re planning a short hedge, just 3 or 4 feet tall, then the very thick poles will not really be a practical option.

Foliage

One of the most important features of a good privacy hedge is some thick, dense foliage. Without tightly packed leaves, the bamboo won’t really provide a satisfying level of privacy. It’s also difficult to create a well-defined, carefully-shaped hedge unless the foliage is very dense. Think of the density of a flat, square boxwood hedge, where you can almost set your drink down on the smooth top surface. Your bamboo hedge won’t get that dense, but at least you want it thick enough to keep the light (and the neighbors) from peeking through.

Climate

Finally, whenever you’re selecting a bamboo plant for your garden, you need to be sure it’s suitable for your climate. Some bamboo varieties prefer, or even need to be in a tropical or subtropical climate. Others can survive, or even thrive, through a snowy New England winter. So always pay attention to the weather requirements before you purchase a bamboo.

Best species for bamboo hedges

There are dozens of varieties of bamboo that will work for a hedge or privacy screen, but here’s a partial list including some of the most common and popular choices. If you know of a good bamboo hedge that we overlooked, please let us know in the comments section.

Arundinaria funghomii: Thin, straight canes of this running bamboo grow close together and with lots of leaves, making it an ideal hedge or screen. Native to China, some classifications consider this a type of Pseudosasa. Grows 20-30 feet tall with 1 inch culms. Cold hardy down to about 0º F.

Bambusa textilis ‘gracilis’: An especially popular and “graceful” variety of clumping bamboo, native to the warmer, tropical climates. A compact growth habit gives this bamboo a small footprint and makes it easy to contain. The upright structure is very attractive and its dense vegetation offers great privacy. Best in zone 8 or above.

Bashania fargesii: Long, sturdy culms have earned this the name of “Wind break bamboo”. Leaves are long and thick, and the culm internodes are unusually long. This cold hardy variety is good in zones 7-10, and gets about 20-25 feet tall, with culms up to 2″ thick. Beware, this species is especially fast-spreading and capable of becoming invasive.

Fargesia dracocephala: “Dragon head bamboo” has thick culms growing to about 10 feet, with a thick, weeping leaf canopy that can provide a good privacy hedge. Not recommended for hot, humid climates, but cold hardy down to -10º F.

Phyllostachys bissetii: A very common variety for privacy screens because it grows so quickly, but be careful, it can also become invasive. Like most members of the genus Phyllostachys, it is a cold hardy runner. This variety can get up to 40′ tall with culms about 2″ in diameter, withstanding freezing temperatures down to -10º F.

Phyllostachys aureosulcata ‘Spectabilis’: A fast-growing, medium-sized bamboo with some interesting features, including a yellow stripe and occasional zigzags in lower sections of the culms. Grows to about 25′ tall and 1’5″ thick with dense foliage. Cold hardy to around -5º F.

Phyllostachys bambusoides

Phyllostachys bambusoides: Giant Japanese timber bamboo, this variety can provide privacy all the way up to the second and third story windows. Smooth, beautiful culms can get 50-70 feet tall, depending on conditions, with a culm diameter of up to 5″. These are running varieties, but not especially aggressive. Cold hardy down to 0º F, but they grow larger in warmer climates.

Phyllostachys humilis: A smaller member of the genus Phyllostachys, only growing 10-15 feet tall, depending on the climate, with culms less than 1″ thick. But despite the size, it can spread aggressively, so keep an eye on the roots. With thick, green foliage, this variety is ideal for hedges and shorter privacy screens. Cold hardy down to around 0º F.

Phyllostachys viridis ‘Robert Young’: An exquisitely attractive variety with green and yellow stripes on its poles, this species can also grow to an impressive but manageable size, up to 40 feet tall with culms up to 3″ in diameter. Depending how much privacy you need, you may want to prune back the leaves on the lower portions (bottom 3 or 4 feet) to show off the beautifully variegated canes. Cold hardy down to 5º F.

Pseudosasa japonica: Known as “Arrow bamboo” for its straight and slender culms, it also makes an especially attractive screen, with large, dark green leaves. Ideal for shorter screens and hedges, with canes growing 15-20 feet tall, and less than an inch thick. Spreads rather aggressively and cold hardy to about 5º F.

Shibataea kumasaca: A less common variety, but perfect for low hedges. Foliage — made up of short, stubby leaves — is unusually dense, with pencil-thin culms that only get about 5-7 feet tall. Despite its diminutive size, this species is a runner and may become invasive if not properly contained. Tolerates shady areas and cold hardy down to 5º F.

Shibataea kumasaca makes an ideal, unusual, compact bamboo hedge.
