Bamboo is a versatile, ancient plant that shows up in creation myths as well as in pots on Manhattan terraces. It comes in clumping varieties that behave themselves and running "timber" types that spread by rhizomes -- great for a grove, but not so good when they are planted as a property screen that escapes into a neighbor's yard.
But it's that very vigor that has environmentalists hailing bamboo as the new "it" plant for saving the earth.
Bamboo is a workhorse at sequestering carbon dioxide and pumping out oxygen. It is a tough plant that manufactures its own antibacterial compounds and can thrive without pesticides. And its porous fibers make a cloth that breathes and is as soft as silk. In fact, there is such a stampede of fabric designers to China and Japan, where it is farmed and processed -- no such industry exists in the US -- that in its May issue, National Geographic predicted that "this upstart fabric may someday compete with King Cotton."

Yet as the world clamors for more, bamboo is in short supply. A plant that generally flowers only every 60 to 120 years and then dies is hard to propagate from seed. And growing it by dividing existing plants is notoriously difficult.
So when Jackie Heinricher and Randy Burr figured out how to make bamboo in test tubes -- selling their first 2,000 plants in 2004 to local garden centers in the Skagit Valley in Washington -- they made waves in the world of horticulture.
"It's funny, because bamboo has this reputation for taking over the universe, and yet it's the hardest plant to produce," Heinricher, a biologist, said one afternoon in early June at the production center for her company, Boo-Shoot Gardens, here in Mount Vernon, a town about two hours north of Seattle.
Heinricher, who grew up with bamboo -- her father tended golden bamboos all around their house in Olympia, Washington -- first tried to propagate the plant in the late 1990s in a little greenhouse at her home in nearby Anacortes, where she lives with her husband, Guy Thornburgh, a marine biologist, and where she founded Boo-Shoot Gardens in 1998.
"I got interested in noninvasive bamboos early on, knowing that they were very beautiful, but impossible to make," Heinricher said. She quickly realized just how impossible, as she tried to divide some of her own rare specimens and watched many die.
So she persuaded Burr, an owner of nearby B&B Laboratories, to help her. Burr and his company had been in business for almost 30 years, with a 1,300m2 tissue culture lab and 3,700m2 of greenhouses. B&B had pumped out plants as varied as rhododendrons and cauliflower, and had figured out how to tissue-culture the Boston fern in 1973, for a nursery in Oxnard, California, and thousands of other plants.
"But bamboo was the hardest," Burr said, looking back over eight years of trying seemingly endless combinations of variables to trigger bamboo to regenerate in a test tube.
When I asked what finally worked, Burr stared back deadpan and said: "We'd have to shoot you."
Bamboo fibers are a renewable resource for fabric, food and paper. And experimental plantings in Alabama financed by the Agriculture Department between 1933 and 1965 showed bamboo's promise for paper and other wood products -- bamboo produced 13 tonnes of wood an acre, as against seven for loblolly pine, a major source of timber in the US.
Planted in large groves, bamboo can store "four times the carbon dioxide of a stand of trees of similar size," Heinricher said, citing a study by Jules Janssen of the Technical University Eindhoven in the Netherlands, in 2000.
"And it releases 35 percent more oxygen," she said.
Many of these plants can now be produced on a vast scale, which is revolutionary for the garden industry. Countries like Belgium have explored the tissue-culturing of bamboo, but Boo-Shoots appears to be taking the lead.
In the old days, bamboo had to be divided and grown to marketable size in a cycle lasting three to five years. Now Monrovia and other growers can buy trays full of young plants from Boo-Shoots, which are potted up and sold as a finished product to other wholesalers and retail nurseries across the country.
Developing tissue culture is a time-consuming process, Burr explained, in which a tiny cutting is sterilized in bleach, then put into a soup, or agar, of inorganic salts, plant sugars, hormones, vitamins and "all the building-block components that encourage tissue to generate and shoot new growth." Getting that formula right can take years.
And the rooting stage is tricky, too. "We'd put out 10,000 plants and lose 10,000," Heinricher said.
Super Typhoon Kong-rey is the largest cyclone to impact Taiwan in 27 years, the Central Weather Administration (CWA) said today. Kong-rey’s radius of maximum wind (RMW) — the distance between the center of a cyclone and its band of strongest winds — has expanded to 320km, CWA forecaster Chang Chun-yao (張竣堯) said. The last time a typhoon of comparable strength with an RMW larger than 300km made landfall in Taiwan was Typhoon Herb in 1996, he said. Herb made landfall between Keelung and Suao (蘇澳) in Yilan County with an RMW of 350km, Chang said. The weather station in Alishan (阿里山) recorded 1.09m of
NO WORK, CLASS: President William Lai urged people in the eastern, southern and northern parts of the country to be on alert, with Typhoon Kong-rey approaching Typhoon Kong-rey is expected to make landfall on Taiwan’s east coast today, with work and classes canceled nationwide. Packing gusts of nearly 300kph, the storm yesterday intensified into a typhoon and was expected to gain even more strength before hitting Taitung County, the US Navy’s Joint Typhoon Warning Center said. The storm is forecast to cross Taiwan’s south, enter the Taiwan Strait and head toward China, the Central Weather Administration (CWA) said. The CWA labeled the storm a “strong typhoon,” the most powerful on its scale. Up to 1.2m of rainfall was expected in mountainous areas of eastern Taiwan and destructive winds are likely
The Central Weather Administration (CWA) yesterday at 5:30pm issued a sea warning for Typhoon Kong-rey as the storm drew closer to the east coast. As of 8pm yesterday, the storm was 670km southeast of Oluanpi (鵝鑾鼻) and traveling northwest at 12kph to 16kph. It was packing maximum sustained winds of 162kph and gusts of up to 198kph, the CWA said. A land warning might be issued this morning for the storm, which is expected to have the strongest impact on Taiwan from tonight to early Friday morning, the agency said. Orchid Island (Lanyu, 蘭嶼) and Green Island (綠島) canceled classes and work
KONG-REY: A woman was killed in a vehicle hit by a tree, while 205 people were injured as the storm moved across the nation and entered the Taiwan Strait Typhoon Kong-rey slammed into Taiwan yesterday as one of the biggest storms to hit the nation in decades, whipping up 10m waves, triggering floods and claiming at least one life. Kong-rey made landfall in Taitung County’s Chenggong Township (成功) at 1:40pm, the Central Weather Administration (CWA) said. The typhoon — the first in Taiwan’s history to make landfall after mid-October — was moving north-northwest at 21kph when it hit land, CWA data showed. The fast-moving storm was packing maximum sustained winds of 184kph, with gusts of up to 227kph, CWA data showed. It was the same strength as Typhoon Gaemi, which was the most
