Light
- Low light 3+ mol
- Medium light 6+ mol
- Bright indirect 10+ mol Copes
- Direct sun 12+ mol Best
Indoors it wants a high-light spot such as a windowsill that gets at least some direct sun; outdoors it is sited in sun to part sun.
Direct sun: needs several hours a day.
On our scale it grows well from about 12 mol/m²/day and holds on down to roughly 2.2 (how these numbers are set).
Care
Care level: Easy. Water: Let the soil dry out between waterings, use room-temperature water, and water less in winter.
Overwatering is the main cause of problems; it rarely flowers indoors.
