    I grew these plants when my kids were young, they loved them. We were thrilled to find them at Monticello. Apparently, Thomas Jefferson found them interesting and sowed them as early as 1811.

    “Plant neurobiology”? Wow, this makes me want to go back to college for another degree! So fascinating.

    Did these plants “learn” to not respond to the dropping or did they
    lose the ability to respond? If branches were stroked the same number
    of times, would they keep closing up or did they “learn” not to respond in that case also?

    Hi Tamara,
    Dr. Gagliano found that plants that had stopped responding to being dropped still closed when they were shaken, proving that they had learned, and were not just too tired to close.

    How do they respond to wind? Do they spend all the time with leaves dropped until the next calm day, or does the non-dropping action kick in and stay kicked in permanently?
    Too many studies on this plant are done in greenhouses, and not in the real world!

    I live in hawaii, and this stuff is everywhere. It’s really cool to see it close, and this new study is fascinating! But oh my, what a pest this species is! It is often growing prostrate in my lawn, and it’s little thorns always find the soft part of my foot
