Flowering of bamboos is rare, it tends to be sporadic when some culms flower or gregarious, when all the individuals in the population flower at the same time and in different areas. Some species of woody bamboos die after flowering while others do not. Chusquea scandens Kunth is a woody bamboo very abundant in high mountain ecosystems and populations in the study area were flowering. To determine the characteristics of the flowering of C. scandens, we selected two populations located in a rural area of ​​Bogotá. On each population we evaluated the phenological stages and growth rate often vegetative culms and ten in the beginning of flowering. In the population that presented a wide area of flowers, it was investigated what happened to C. scandens after flowering. The association of C. scandens with other species of both native and exotic forests, could be one of the factors influencing its flowering. The flowered patch showed drying and subsequent colonization by pioneer species. During the study period C. scandens showed evidence of being a monocarpic species. The strategy of flowering C. scandens, was different from other species of Chusquea, in the shorter time a culm developed from a bud to a fruit with seeds well as in its   sporadic flowering.
