Description

Beautiful cold hardy giant bamboo. Canes emerge green and turn ghostly gray color with sunlight exposure.

Bamboo Panda

Why choose this bamboo?

  • Canes have a blue/gray ashy appearance when mature.
  • Tallest effective screening bamboo.
  • One of the most drought tolerant of all species.

Phyllostachys Nigra 'Henon' Giant Gray Bamboo is an impressive giant bamboo. This bamboo can form a great screen from about 6'-35'. Giant Gray is my favorite bamboo not only for the size and unique color but also the ability to grow great in shaded sites with poor soil and watering. Known best for its drought tolerance once established.

From Guangdong Sichuan, China this cold-hardy giant has very erect canes. The new olive green canes turn into a ghostly gray color with age. The culm sheath has wavy blades with prominent oral setae, auricles, and ligules.'Giant Gray Bamboo' grows well under a large variety of conditions, even in heavy clay soil. This is the third most grown bamboo in Japan for timber.

Climate Zone 7 expect mature size canes to be over 60 feet in height.

Climate Zone 6 expect mature size canes to be over 40 feet in height.

Climate Zone 5 it is being grown to around 18 feet with moderate top damage during winter months.

Giant gray bamboo is used in many commercial applications because of its striking appearance and low maintenance requirements. The wood is of high quality and used by many craftsmen.

This is a green form of 'Black' bamboo that assumes a gray-blue cast as the culms start to mature, giving it a ghostly gray appearance. It is a large timber bamboo and thought to be the "mother" form of the Phyllostachys Nigra 'Black' bamboo.

Plant introduction number (PI) into the U.S. 75158

Common Japanese name for Phyllostachys nigra 'Henon' is Hachiku

How Bamboo Grows

Bamboo grows a little different than most plants. The bamboo that you get initially never grows vertically again. It has babies that are taller, that has babies that are taller. Every generation should be taller that the previous year's shoots. The intriguing aspect is that each year’s growth emerges and grows to it complete height in 60-90 days. They spread as they produce larger growth, filling in and providing a screen.


This link will help you learn how bamboo grows. It will give you an idea of what kind of growth to expect from your planting. It is a lot of information, but well worth your time. How Bamboo Grows

Planting

Planting bamboo is also easy. You want to dig a hole about twice the size of the root ball. When you plant the bamboo amend your soil with composted manure and a good top soil. Bamboo can be planted at ground level or slightly deeper. It is not a picky about it conditions but this will help get it off to a good start.

Correct planting depth for bamboo plants

More details can be found on our Planting Instruction Page

Spacing

One division of bamboo will start a grove or screen over time. However, if you want a privacy screen fast, we recommend planting bamboo 3 to 5 feet apart. This will hopefully allow you to have a good screen in three years. There are a lot of factors such as water, sunlight, and climate zones that speeds up or slows down the process. Three years is about the average on this spacing, closer planting will allow you to screen or develop your grove faster. You cannot over plant bamboo.

Maintenance

Fertilizer

Bamboo can benefit from a fertilization program. You can safely fertilize your bamboo once it has been in the ground for one month. A time release fertilizer will work great. Time release fertilizers allow for proper absorption in case your soil is out of PH balance. We offer some fertilizer to help with growth. We fertilize twice a year. Once in the early spring to encourage new growth and then again during the middle of the grow season to replace any nutrients that are being depleted.

Control

Over the years a lot of myths have been told about bamboo, while it can spread under good conditions, it is not as invasive as many people would have you believe. In colder climates an aggressive runner here in the south will hardy spread at all in comparison. We have been growing bamboo since 1985 and had experience with it long before that. The bamboo's underground root system (rhizome) will spread beyond the initial planting over the years, so in the next two or three years you will need to decide on some method of containment on the sides you do not want the rhizomes to run over into.

We have constructed a page discussing multiple methods of controlling bamboo. It goes over root pruning, mowing new shoots, and in ground barriers: Controlling Bamboo

All this said and it may discourage you, but as with any plant there will be maintenance. Bamboo is very beautiful and is great in a Japanese style garden, but it will need maintenance down the road. At first it may seem to be doing nothing, but after 3 to 5 years you will have a lot of beautiful culms (canes) and love the foliage. All our 150 plus species simply contained by mowing and weed eating the new Spring and Summer shoots. Hopes this helps and don't be afraid of the bamboo.
