What these share
Derived from the 3 entries above, not asserted about the family at large.
| Watering range across the family | Every 10 to 21 days for a 6-inch pot indoors |
|---|---|
| Native habitat recorded | semi-arid, canopy epiphyte |
| Toxic to cats and dogs | 0 of 3 |
| Least demanding here | String of hearts, Easy. Scores 2 of 5: drought-tolerant, fast, and it produces aerial tubers along the strand that root by themselves. Overwatering is the only real risk. |
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.
