339/365 Flower or plant?

Flowers whose blooms appear to just be a leaf of a different color are rather interesting. Are they flowers? Leaves? Just plants?

This bromeliad, as well as the ones I saw at my eye surgery, is an example of that kind of flower/plant. The "bloom" seems to be just a colored collection of leaves.

Another good example is a poinsettia. Then there's the pineapple. Would you believe a pineapple is a bromeliad? Instead of producing this vibrant red "bloom," it sprouts prickly fruit instead.

It's kind of crazy, especially when you think that the point that differentiates them is a minuscule gene.
