The Stromanthe Sanguinea is a nyctinastic plant, which means that it moves its leaves up and down during the day using little hinges at the bottom of their stems. In particular she closes up when the light is very bright, and opens up again when it gets cooler, moving with the rhythm of the day! And if you are very quiet you can even hear a light rustling sometimes, as she shifts position like a baby having growing pains. With a little love and care she will grow into a beautiful houseplant that will brighten up your hallway or bathroom.
