Quick Scoop

If you’re planning space for one, a normal houseplant peace lily is often a medium-sized floor or tabletop plant , not a giant. Growth depends a lot on the variety, pot size, light, watering, and overall care.

Typical size

  • Indoor: about 16 to 28 inches for many common varieties, with some reaching 3 to 4 feet.
  • Outdoor in warm climates: often 3 to 4 feet , and some cultivars can grow up to 6 feet.
  • Dwarf types: about 12 to 15 inches tall, sometimes smaller.

What affects size

  • Variety/cultivar: some are naturally compact, others are much larger.
  • Pot size: larger pots usually allow more growth.
