You can take China’s Bamboo seed and plant it on ground. Water, nurture the seed for an entire year and you will not see even an single sprout. In fact you will not see a single sprout for 5 years.
But suddenly and finally a tiny sprout will spring from the ground and over the next 6 weeks the plant can grow as tall as 90 feets. It can grow as fast as 39 inch in every 24 hours. You can literally watch the plant grow.
