What these share
Derived from the 2 entries above, not asserted about the family at large.
| Watering range across the family | Every 12 to 21 days for a 6-inch pot indoors |
|---|---|
| Native habitat recorded | arid |
| Toxic to cats and dogs | 2 of 2 — pyrrolizidine alkaloids |
| Least demanding here | String of bananas, Easy. Scores 2 of 5: the string-of plant to buy first. It has the same look as string of pearls with none of the fragility, because the thicker leaves and deeper roots forgive a watering mistake. |
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.
