Green Power first noticed the Bauhinia aperilobata, of the same family as the city’s official flower, the Bauhinia blakeana, during an ecological survey of Sha Lo Tung in Tai Po last June. The flowering plant is a vine, climbing around larger trees towards the canopy where there is more sunlight. “The discovery of the Bauhinia aperilobata confirms Sha Lo Tung’s ecological value,” said Tommy Yu Kin-kong, Green Power’s assistant education and project manager.
