The moist makes sense. You all have heard me say in the winter I am a no water girl.
My Mom was a housewife of the 50s and I do remember her watering her plants a lot. She always had this prayer plant. Maybe I will put it in the Terrarium this winter with the begonias.
Christine, Something funny for these type of plants of making that noise and the leaves moving. I was use to seeing the plant pray living because of my mom having the plant all my life. They were never big so it was not a scary sound as my Stromanthe sanguinea tricolor. I had this plant on a table beside a bench the first summer I had the plant and when it did that sound and the leaves moved I jumped up and started running. It was evening and I like to sit outside after the sun goes down and it is pretty dark here.
Imagine a plant this big making that sound and these many leaves moving.
