Bright indirect
LowMediumBright indirectDirect

Water
Every 7–14 days
Baseline for a 6-inch pot indoors. Check first: water when the top inch is dry, not on a schedule.
Humidity
45% and up
Wants 60%. Struggles in dry winter air.
Difficulty
Easy

Habit
Trailing
Grows to 12–72 inches. No support needed.
Non-toxic to cats and dogs
Eating a large amount of any plant can still cause mild stomach upset.
