Cheryl, the first time I saw the leaves move I jumped up and started running.
I thought something was under the leaves.
It was evening and I had it up on a table beside the seating area. I have seen prayer plant move but the leaves are more of a slower movement. Maybe because the leaves are bigger on this plant why it looked more aggressive.
That is why it is on the patio floor. I did not know for a few weeks that it is the leaves reacting to the light. It even does it through the day if the sun changes or cloud move over the sun.
