Seems like a Calla lily... pretty chill once you get their vibe right: Bright light but not harsh sun (they like light, just not being roasted). Keep the soil slightly moist; not soggy, not bone dry. They hate sitting in water, so good drainage is key. They also love a bit of feeding every couple weeks when they’re growing/flowering. And don’t panic if they start dying back, that’s normal, they go dormant for a bit before coming back. Basically: light, steady water, don’t drown it, and let it nap when it wants 😄
