ZZ Plant (Zamioculcas Zamiifolia)The Zamioculcas Zamiifolia (commonly known as the ZZ Plant), is one of the hardiest houseplants around. They can tolerate very low light, but will grow faster and larger in bright, indirect light. Their bulbous roots store large amounts of water, so they only need watered about once every 2 4 weeks (depending on how much light they're getting). Allow the soil to dry out completely in between waterings. ZZ plants are extremely poisonous if eaten and
