Native to flats and slopes in the southwestern region of the Western Cape, growing in low-lying, wet areas in fields
When grown as a summer grower in warmer climates, or under lights, the foliage will form nice, tight mounds. In weaker winter light or shade, specimens will be more lax in habit.
In researching this plant, I found that this is one of the Oxalis species that love moisture when in growth, and appreciate discontinuing of all water during the summer (which in nature would be their resting period). Start back with watering in September, as that is when the shorter days and cooler temperatures will trigger them to continue growing.
