Query: Don't grow in humid climates

I thought this would be a great educational Christmas gift for my sons since I thought the plant would be low-maintenance and hard to kill, even if they forgot to water them. The fern did unfold and turn green, which fascinated them. However, even though we rinsed them and changed the water daily, within 3 weeks both plants had developed white mold (FYI, we live in Georgia). We plan to plant them outside in the yard (after I check to make sure that's legal) so the mold doesn't grow in the house. Definitely NOT low-maintenance, and not for homes with high humidity/mold issues.
