I have a plant that is fine when watered, but as soon as the soil dries out the leaves roll up into little balls. Do you know the name of this plant by chance??
Your plant is called a Resurrection Plant. A resurrection plant is any poikilohydric plant that can survive extreme dehydration, even over months or years. When not watered, the leaves curl up, turn brown, and the plant looks dead. Once watered, the plants returns to its original green state. Amazing! Your particular Resurrection Plant is called Selaginella lepidophylla (Rose of Jericho).
