I know I repeatedly post on the same stuff but sometimes that's because I'm tracking the developmental changes and progress of the plants over a period of time.
So this Couroupita shed it's leaves not too long ago and now it has regained a full crown of leaves. Plants are so amazing and full of life. The amount of energy that goes into such processes must be immense. I can't imagine the amount of energy reserves it stores in it's trunk, roots etc.
