This is a video of Colcoasia 'Big Dipper that I just took today during a nice rain storm(Fianlly! It rained!). The video may not be the best quality because I took it with my cell phone.

The video shows how the leaves fill with water and then dump out the rain water. They are really fun to watch when it does rain. This Elephant Ear is suppose to be hardy to zone 6.
