Question 1

True or false: Peace lilies are completely safe for cats and dogs to eat.

Accepted Answer

False. They contain calcium oxalate crystals, which cause oral irritation, drooling, and vomiting if ingested by pets.

Question 2

True or false: Peace lilies thrive best in direct, bright sunlight for at least six hours a day.

Accepted Answer

False. They are low-light plants—direct sun scorches their leaves. Bright, indirect light is ideal.

Question 3

True or false: The white 'petal' of a peace lily is actually a modified leaf called a spathe.

Accepted Answer

True. The showy white part is a bract—a specialized leaf—while the tiny flowers are on the spadix inside.

Question 4

True or false: The peace lily was first discovered in the rainforests of Madagascar.

Accepted Answer

False. Peace lilies are native to tropical regions of the Americas and Southeast Asia, not Madagascar.

Question 5

True or false: Peace lilies are not true lilies but belong to the Arum family.

Accepted Answer

True. Despite their name, peace lilies are in the Spathiphyllum genus, not the Liliaceae family—they're closer to calla lilies.

Question 6

True or false: Peace lilies bloom more profusely when kept in total darkness for two weeks each year.

Accepted Answer

False. Peace lilies need bright, indirect light to bloom; extended darkness stresses the plant and prevents flowering, not triggers profuse blooming.

Question 7

True or false: Peace lilies can remove formaldehyde from indoor air.

Accepted Answer

True. NASA's Clean Air Study in 1989 identified peace lilies as effective at filtering formaldehyde, benzene, and other volatile organic compounds from the air.

Question 8

True or false: A peace lily's leaves will turn yellow if it's watered with tap water containing fluoride.

Accepted Answer

False. Fluoride toxicity in peace lilies typically causes brown leaf tips, not overall yellowing. Yellow leaves are more often due to overwatering, low light, or nutrient issues.
