What these share

Derived from the 4 entries above, not asserted about the family at large.

Watering range across the familyEvery 3 to 14 days for a 6-inch pot indoors
Native habitat recordedcanopy epiphyte, tropical understory

Least demanding hereBlue star fern, Easy. Scores 2 of 5: by a distance the easiest fern to keep indoors, because it tolerates drying slightly and does not demand 70% humidity. The furry surface rhizomes are supposed to sit on top of the mix.

Family membership is a rough guide to care, not a rule. It predicts toxic principle far better than it predicts watering: species in the same family routinely come from different habitats, and habitat is what sets the interval. Read the individual entry before acting on anything here.
