Leaf heteroblasty in Costus pulverulentus helps the plant adapt to its environment by changing the size and shape of its leaves as it grows. The plant develops two different leaf forms: basal leaves at the bottom and top leaves at the top. Mid-crown leaves in between have different characteristics to maximize light capture. Plants with top leaves have better light capture efficiency due to less self-shading and lower crown density. This adaptation allows the plant to make the most of available light, giving it an advantage in its ecological niche.
