REASON WHY KURINJI FLOWER GROWS ONLY ONCE IN 12 YEARS

Kurinji is a type of flower which grows once in twelve years with a large population at a particular site. Kurinji is also known as strabilanthes. The number of flowers at different places may have different growing dates, but the length of the cycle is almost the same. This is one of the processes by which plants survive. By this process, they escape destruction, which is caused mainly by seeds or flowers predators. This is termed as ‘predator satiation’. In trying to synchronize with a large number of population, the predators are simply getting extinguished.
As they are getting extinguished, the number of population which is destroyed by predators is becoming less. The main predators of kurinji seeds include jungle fowl and small mammals. In long-term intervals, plants that synchronized with flowers include bamboos, oaks and beeches.
Do we all know how plants ‘count’ there no of years? They count them by recording changes which are made during the day length. They also have an internal calendar, which helps to find differences in day length. This internal calendar usually changes with change in the environment. So, different species of plants wait for different periods in order to flower and grow.
