Oxalis triangularis requires bright indirect sunlight supplemented with a cool indoor temperature of 15 °C (59 °F). It can tolerate higher indoor temperatures, but will go into dormancy prematurely and/or begin to take on a "tired" appearance if temperatures exceed 27 °C (81 °F) for prolonged periods of time.

At lowered light levels the leaves fold down; timelapse recorded at ~750x actual speed and covering a 1.5 hr period of time. In biology , nastic movements are non-directional responses to stimuli (e.g. temperature , humidity , light irradiance ) that occur more rapidly than tropisms and are usually associated with plants .

It is a physical barrier to germination, not a true form of dormancy (Quinliven, 1971; Quinliven and Nichol ...
