Landscapers in Beijing have developed new technologies to create a greener environment for the Olympic Games in 2008.
In summer, Beijing is short of flowers but the city leaders aim to turn the capital into a city "shrouded in green and wreathed with flowers,"  Beijing News reported yesterday.
Scientists and technicians with the Beijing Gardening and Forestation Bureau said they have developed ways to enable flowers to stay in bloom longer. The list includes chrysanthemums, roses and other homegrown flowers.
They are also studying ways of transplanting trees from forests in the suburbs to downtown venues for the Olympics. This includes spraying powder to protect roots and planting them in special containers.
A "green roof" project will plant plants on the rooftop of buildings near Olympic venues.
