I've had my Spathiphyllum wallisii for about three years now, and I'm still puzzled by something. Mine sits in bright indirect light in my arid climate, but it droops dramatically even when the soil is moist—way more than the typical "I need water" signal people describe. I'm wondering if anyone else's peace lily does this, or if mine's just moody. The leaves still look healthy, but that daily drama is exhausting to watch.
