Harvest Tips

Fun Facts
- 🌱 Pink Peace Lily's white spathes are not true flowers—they are modified leaves called spathes that surround the actual tiny flowers on a rod-like structure called a spadix, similar to calla lilies.
- 🌱 The plant's common name 'Peace Lily' references its elegant white spathes, which resemble flags of peace. It became popular in the 1980s after NASA included it in studies of houseplants that purify indoor air.
- 🌱 Pink Peace Lily naturally 'tells you' when it needs water by dramatically drooping, then reviving quickly after watering—making it an excellent plant for forgetful gardeners who need a visible reminder.
