Flowers once in a life-time
On the basis of the frequency of flowering or fruiting in the lifetime, plants may be either monocarpic or polycarpic. Monocarpic plants are those, in which flowering and fruiting occur only once in their life, e.g., all annual and biennial plants and some perennial plants like bamboo and Agave. In contrast, polycarpic plants bear flowers and fruits repeatedly after attaining maturity, e.g., mango, Acacia, Eucalyptus, etc.
