Parlor palm vs Peace lily
Chamaedorea elegans · Spathiphyllum wallisii

The differences that matter
Pet safety

Mature size
Parlor palm reaches about 48 inches; Peace lily tops out near 24. Buying the wrong one for a shelf means rehoming it in a year.
Not even related
Parlor palm is Arecaceae, Peace lily is Araceae. They share a shop label and nothing else — different families, different continents, different care.
Which should you buy?
- With a cat or dog in the house, take Parlor palm. The other is toxic, and if the shop label is wrong you will not know which you have brought home.
- In a dim room, take either — both have a low light floor.
- If you forget to water, take Parlor palm, which goes 8 days between drinks.
- If it is your first plant, take either — both score 2 of 5.
- For a small shelf, take Peace lily, which stops around 24 inches.
