Running Bamboo is the most widely grown, fast growing type of bamboo plant in the world, and is comprised of over 700 species. The most widely used and possibly the 'King' of the running bamboo in the Phyllostachys genus, which is comprised of approximately 80 species. The most fast growing, popular bamboo species are Phyllostachys aurea (Golden Bamboo or Fishing Pole Bamboo); Phyllostachys bambusoides (Giant Timber Bamboo); Phyllostachys nigra (Black Bamboo); Phyllostachys nigra 'henonis' (Blue Bamboo); Phyllostachys pubescens (Moso Bamboo); and Phyllostachys sulphurea (Robert Young Bamboo). Golden Bamboo or fishing pole bamboo plants, as they are called in the south, have a light-green to golden colored stalk, that grow fast to ½ – 2 inches in diameter, and up to a 30 feet tall with similar colored leaves and poles. Golden Bamboo was the first of the Phyllostachys bamboo cultivars to be introduced into the United States, in 1882. In Alabama, where bamboo was to be primarily used as a fast growing windbreak, it was planted by southern tobacco farmers. The poles from the golden bamboo have probably landed more fish in the southeastern U.S. than any other means of fishing, hence the name, fishing pole bamboo, Phyllostachys aurea. Giant Timber bamboo has dark green to golden stalks that grow large to 100 feet tall, and up to 6 inch poles in diameter with green foliage.
A popular known grown bamboo is Japanese timber bamboo, Phyllostachys bambusoides, because of its introduction from Japan in the 1910's. This giant timber bamboo was expected to be a huge commercial success by the U.S.D.A. for its use in erosion and construction, and for its nutritious edible shoots. The possible uses as a renewable U.S. Forest bamboo tree product has never been exploited, due to the resistance and opposition of the powerful U.S. Lumber Industry, and lobby, which had its investments planted into the vast non-renewable pine and oak forests that once existed in the lower half of North America.
Black bamboo, Phyllostachys nigra, is fast growing with a shiny, green stalk, that changes into a dark-purple or black color over the period of approximately 18 months. The black bamboo culms (stalks) are 1 - 2 inches in diameter and grow to reach a pole height of 30 feet with the beautiful contrast of green leaves. Black bamboo has for centuries, and still today, been considered in China and Japan to be the "Crown Jewel" of the bamboo world. Emperors and aristocrats alike adorn their private gardens with this choice black bamboo species. Black bamboo is highly regarded for cabinet work and a must for the coffins of wealthy oriental families, a symbol of beauty and success. Black bamboo typically brings the highest dollar to buy at garden centers for its unparalleled ornamental beauty.
Blue Bamboo, Phyllostachys nigra 'Henon', also known as the Henon Bamboo, or Phyllostachys nigra 'Henon'. Henon Bamboo, however, is larger than black bamboo, with pole stalks reaching 3 ½ inches in diameter and a height of over 50 feet. The Blue Henon bamboo stalk is light-green in color, but after time builds up a hazy layer of silicon on the surface, that gives a grayish-blue appearance. The Blue Henon bamboo color is contrasted by its green leaves. Known as Blue bamboo, due to this silicon build-up, blue Henon bamboo is like its relative, black bamboo, rare and highly prized. Blue Henon bamboo is typically grown for its ornamental value only.
Moso Bamboo (Phyllostachys pubescens) is the most valued commercially used bamboo species in the world with millions of acres in use. Moso bamboo pole stalks are considered among the biggest and most beautiful, growing to a diameter from 3 – 7 inches and towering to 80 feet with clusters of relatively small green leaves. The possible uses of Moso bamboo seems endless, ranging from food, construction material, paper, irrigation, medicine, musical instruments, beer, even diesel fuel. Yes, if the "powers that be" would allow, this bamboo might be used to change the economy of the world and the lives of billions. Moso bamboo is considered to be of infinite beauty, growing huge, arching culms swaying in the wind, growing with masses of tiny leaves to gives the image of giant pale-green ostrich plumes. This beautiful visual effect has recently caught the admiring attention of millions of viewers in Hollywood productions, such as Crouching Tiger, Hidden Dragon, The Last Samurai, and other films from bamboo plants growing in the forests of China. The rare, highly sought after abnormal forms of Moso bamboo with pot-bellies on internodes in tight clusters; Sometimes slanting nodes, or even in zig-zag deformities are interesting. These Moso bamboo poles are called 'Tortoise-shell' bamboo, and are highly prized to buy and grow for their use in expensive handcrafts or furniture. Moso bamboo, as all species, is a renewable resource, and the new moso bamboo plants regenerate from the roots after cutting. Therefore, if grown as a source for paper products, Moso bamboo could rival the lumber industry in power today, and would be more compatible to our environment.
Robert Young Bamboo, Phyllostachys sulphurea, is also a very large bamboo, with golden stalks of green pin-stripes topped with dense green leaves. The pole stalks grow from 2 – 6 inches in diameter and grow up to 50 feet tall. Robert Young Bamboo is named after its discover and is predominantly used as an ornamental variety only.
The running bamboo species spread by underground rhizomes that extend into a 360 degree growth pattern, and can grow indefinitely. The roots are, however, shallow (only 1 ½ – 2 feet deep) and may be largely controlled by root barriers made of thick gauge plastic or concrete units. Hotels and private patios around the world, plant and grow these prized ornamental bamboo in terracotta or cement planters. This bamboo growing method does restrict the bamboo plant's ability to reach its potential maximum large size. Running bamboo species are widely planted for fast growing erosion control, privacy screens, and wind breaks, and the bamboo can be trimmed to the desired height. Bamboo in general is not particular concerning soil type, although a neutral soil (pH = 7) is preferred. Bamboo can also tolerate full sun or partial shade conditions. Despite misconceptions, bamboo culms (stalks) emerge largely in the spring with a consistent diameter that each individual pole stalk will always have. Each year, as the bamboo root mass grows larger and stronger, larger and larger culms will emerge until it grows to that particular species' maximum diameter.
Flooring professionals are always looking to source flooring to their commercial and residential clients that will stand as being both visually attractive as well as long-lasting. Homeowners are looking for these benefits too, but many people are becoming more and more aware of the issues of renewability and the protection of the environment. This awareness has caused many people to seek alternate sources of flooring materials that will still serve the needs of look and practicality, but with the added benefit of sustainability of natural resources. One of the most popular choices for these reasons remains to be bamboo flooring. Bamboo is noted for hardness, beauty, variety, and its “green” friendly nature. But, how exactly is it made, how many types are there, and just what makes it so renewable anyway?
Bamboo Is A Type of Grass
A common error some make about bamboo is that it is a type of hardwood. Not to be confused with common associations of many species of grass, bamboo is actually a type of grass which matures into a material that can rival the hardness of maple! Being well adapted to the environment in which bamboo commonly grows, each bamboo plant thrives in areas of fair to poor soil quality, and still remains to be one of the fastest growing plants in the world. Controlled harvesting of the bamboo plant has very little impact on each individual stalk, which will continue to grow long after harvesting. This is what makes bamboo such a renewable source of flooring material, and why it is often associated with environmentally minded choices for flooring. The fact that it is such a uniquely attractive flooring option makes bamboo flooring an extremely beneficial choice for your own interior environment!
How Bamboo Flooring is Made
Once the bamboo has been harvested, the outer layer of green “skin” is removed and each stalk is cut into lengthwise strips or “fillets”. These curved fillets of bamboo are milled along their outer edges in order to flatten them. The excess elements of this process will go into another type of bamboo flooring that is called “strand-woven bamboo flooring” – more on that later. The flattened strips of bamboo are then kiln dried in order to remove the natural moisture in the bamboo, and are then boiled. The bamboo fillets are now ready to be glued together to make a solid, dependable surface that is more than suitable for flooring. The bamboo undergoes one final compression stage, which makes it that much more durable and ready to ship. Tongue and groove elements are added in order to make an installation as easy as possible. It should be mentioned that the outcome of this manufacturing process is dependent on which kind of bamboo flooring is being made. There are several types of bamboo flooring, both in terms of cut and of color, and some differences in how they are processed.
Horizontal or Vertical Bamboo Flooring
During the gluing process, the bamboo can either be bound with the narrow edges facing up, which results in a thin, channel pattern in the bamboo flooring, or so that the broader surface of the bamboo is bound facing upward, making for a surface that is more akin to traditional hardwood patterns. These styles of bamboo flooring are known as vertical and horizontal bamboo flooring respectively. There are visual benefits for each one, depending on your personal taste, but both remain to be decorative choices. The horizontal style is striking for its “knuckle” or “node” patterns, that is, the pattern naturally occurring in the bamboo that are the equivalent of “growth rings” in many hardwood species. The vertical style is a unique surface that remains unmatched by any other natural flooring material, characterized by decorative, narrow channels caused by the binding of the bamboo strips. Both of these styles are available in natural or carbonized colors.
Natural and Carbonized Bamboo Flooring
Along with choices in style you may wish to consider in bamboo flooring, there is also the question of color. Bamboo flooring is available in two colors – natural and carbonized. The color is determined at the boiling process. Natural bamboo appears in a creamy blonde color that is known to add a touch of brightness to an interior. Carbonized bamboo is characterized by its smoky, caramel hue which is the result of a longer boiling process which causes the remaining starches in the bamboo to caramelize. It should be noted that by the end of the respective boiling processes, the natural remains to be the slightly harder bamboo flooring. The carbonization process which defines carbonized bamboo reduces the bamboo’s hardness by about 30%. It must also be noted that even though this is true, both colors of bamboo flooring can still be classified as being as hard as some hardwood species.
Strand-Woven Bamboo Flooring
In the continuing spirit of a “green” flooring option, strand-woven bamboo flooring is the product of a process that leaves very little wasted. The excess material left over from the filleting process which goes into making natural and carbonized bamboo flooring are intertwined, compressed, and bound. The binding agent is a safe, UV resistant and scratch-resistant resin which also makes the bamboo even more resistant to moisture. The process of compression results in a very hard, very durable type of bamboo flooring typified by grain patterns that are more like those of a hardwood floor. The strand-woven bamboo is then cut into planks and is ready to be shipped – no further compression is needed in this case, unlike regularly manufactured bamboo flooring.
Bamboo: A Renewable Resource Renews Your Interior!
One of the key elements that makes bamboo flooring so attractive is that it is an environmentally responsible choice. As you have read, the harvesting of the individual bamboo plant does no harm to it, and it remains to be one of the fast-growing plants in the world. Also, there is very little wastage of materials during the manufacturing process, making bamboo a truly renewable and sustainable source of flooring materials.
Bamboo flooring can in turn renew any interior for attractiveness as well as practicality. Bamboo flooring is unique in appearance, and is easy to clean. As such, you will gain both the time it would take to maintain many other types of flooring, as well as the many compliments you’ll receive from visitors!
