Thigmotropism. If you took biology in high school, you learned this word. Here's a little reminder...

Thigmotropism is what Botanists call it when plants can respond to touch by moving. The most commonly known example is the Venus Fly Trap. A bug crawls in, the plant senses the touch, and snaps shut to trap the insect. These ferns, which we found along the Hana Highway, are thigmotropic. Very cool!

  1. I love these ferns! I would play with them all day if I had them here. What's their rebound time like?
