A bougainvillea has unexpectedly grown prosperously along the outer wall of a residential building in Guangzhou, south China’s Guangdong Province, for the past twelve years. /VCG Photo

The blooming flowers, photographed on Friday, climb all the way up to the ninth story, creating a splendid “carmine waterfall.” /VCG Photo

These beautiful vines are rapid growers and climbers, and prolific bloomers. Guangzhou has a perfect environment for them to grow: Warm, sunny and with good drainage. /VCG Photo
