Have two HUGE Brazilian Elephant ears in brick planters in front of my house; live in central AR; temps in the winter can go from zero to 80! Really don't want to lose these beauties. Dig up or mulch? Suggestions??

I would mulch; the foliage may die back but the tubers should be ok unless you have a deep freeze.

Teresa: to All Things Plants and great growing with those lovely Elephant Ears!

I agree with Hetty and Ken; the leaves of your plants will die back but a thick layer of mulch should protect the tubers and they should re-sprout next spring. Elephant Ear (Colocasia esculenta) are very tough plants.

Hi Teresa, welcome to ATP.
Your plant appears to be Colocasia gigantea, most likely a native of tropical SE Asia and readily available here in the states. Has it bloomed for you?

Even with mulch on top I'd be concerned about your soil temps in an unprotected brick planter. As Dutchlady noted, a deep freeze will be a problem. Does the soil ever freeze solid in this planter?
