What these share

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

Watering range across the familyEvery 9 to 28 days for a 6-inch pot indoors
Native habitat recordedsemi-arid
Toxic to cats and dogs2 of 4 — bufadienolide cardiac glycosides
Least demanding hereBurro’s tail, Easy. Scores 2 of 5: drought-proof and long-lived. Loses points because the leaves detach at a touch, so it cannot be moved often.

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.
