The stems of many plants resist buckling using low-density foam cores.

BIOMIMICRY TAXONOMY
Summary
"Anyone who has squashed an empty metal can knows about the second form of buckling; it's called 'local buckling' or 'Brazier buckling...Local buckling does occur in biological columns--it's certainly involved in the lodging of slender crop plants in wind storms, and it can be deliberately induced in any dandelion stem. A low-density foam core reduces susceptibility, and many plants (but not dandelions!) have such cores." (Vogel 2003:378)
