SPECIES SELECTION - Bamboos are a primitive sub family of grasses that include over 70 genera and 1,200 species worldwide. They are native to all continents except Europe, Antarctica & the Arctic. The various species are adapted to a wide climatic range from cold temperate to tropical. For any climatic region, except for the extremely dry or cold, there are potentially 100's of species to chose from. In Australia there are 5 native species and the number of species & varieties available from nurseries has gone from 20 -30 in the early 80's to well over 200 today and more are being introduced all the time. Of the 1,200 species worldwide only about 100 rank in the 'Elite Bamboos' being significantly useful.
Care should be taken when selecting species for the garden or farm. All bamboos, both clumping and running forms, use an increasing amount of space as time goes by. Unless they are utilised or very much appreciated, they can become a liability requiring unrewarded effort to control their spread, especially if space is limited. We have realised this over the years and have culled most of the purely ornamental species from our collection without really compromising aesthetics; they are all beautiful and many of the important commercial species are outstandingly so. In a small yard it can often be more advantageous to grow a large clumping variety that produces edible shoots and useful culms than a small ornamental type. Placed in a central position like the middle of a lawn it can provide all the benefits of a feature tree while being kept in check and looking good by the harvest of shoots and culms. The leaves make an excellent 'seed free' mulch for annual gardens.
VILLAGE BAMBOOS - We specialise in 'village bamboos' i.e. those species that the rural folk from countries with a long history of bamboo utilisation have selected and cultivated for food, craft and construction purposes. We are in the process of collecting superior clones of these species from the various regions around the world that may best suit our warm-temperate to sub-tropical climate. These useful species have the potential to make a real contribution towards protecting native forests by providing an alternative material to timber. Bamboo can produce 10 times more cellulose material per hectare per year than even fast growing trees like Pinus radiata, it doesn't require heavy machinery to harvest and is user friendly. With simple tools it can be fashioned into a thousand useful items from toothpicks to houses. In recent years there has been a lot of industrial development - paper, plywood and particle board products made of bamboo; even sheets of corrugated roofing! Other uses of bamboo as living plants include nutrient uptake in waste water, erosion control, windbreaks, hedges & fodder.
With 20yrs of experience with bamboo I have trialed over 150 species to get to our present list. Each year we decide to discontinue certain species for various reasons – pest or disease prone, inferior timber, bad growth form.. etc. So if its not on this list it is very likely not worth growing. As time goes by the bamboo list will be more & more refined.
CLUMPING & RUNNING MODES OF GROWTH - As with other grasses generally, there are basically two modes of growth in bamboos, clumping & running with some variations. Clumping or 'sympodial' bamboos have short fat rhizomes that form clumps. How tight or open a clump is depends on the length of the rhizome neck of the particular species. They are most commonly tropical to sub-tropical with some of them able to tolerate some frost. They produce shoots in late summer and autumn.
Running or monopodial bamboos have long adventitious rhizomes that are cylindrical and segmented like the culms. These bamboos give rise to evenly spaced culms some distance apart. The larger species form groves that resemble timber pole forests, the culms are very straight and because of the light conditions only have branches on the upper portions. They are temperate climate plants that tolerate many degrees of frost and even annual snow cover. They produce shoots in spring and grow best in frost prone situations. In fact, they become stunted in warm situations with insufficient winter chill. Their spread can be controlled in various ways…..by natural boundaries such as:- hard roads; reasonably permanent water courses; grazing or timely mowing. Installing underground rhizome barriers of concrete, conveyor belt rubber, or the like can also control them. The barrier should be dug to 1m below the surface or a hard infertile subsoil layer and allowing at least 100 mm to protrude above ground. In dry areas with access to water they will only grow within the limits of the irrigation. The genus PHYLLOSTACHYS are the most useful of the running bamboos and the only ones that we grow and sell.
