She's large. She's in charge. The Peace Lily Sensation has gigantic leaves and - you guessed it - gigantic flowers as well. Peace lilies symbolize...well, peace of course! They also symbolize healing and hope, making them popular sympathy gifts.They're beautiful white flowers bloom fairly consistently, and their leaves droop when they're thirsty, so you always know what this houseplant needs. While they thrive in medium to bright, indirect light, they are perfectly happy in lower light as well. Water them once or twice per week, and remember to keep them out of reach of pets!
