Oxalis triangularis, or false shamrock, belongs to the genus of herbaceous annuals and perennials of the family Oxalis. There are over 800 species on the planet, with the majority of them found in South Africa, South America, and Mexico, as well as in Europe.
False shamrock leaves are trifoliate or finger-shaped, attached to the stem by a petiole. They have a complicated limb that shuts in the evening and opens in the morning. Too much light and mechanical stimulation cause the leaves to respond.
Depending on the species, Oxalis triangularis leaves can be green, purple, or burgundy in color. Its blooms are tiny and regular, with white, pink, purple, or yellow petal colors. Flowers close at night or before the rain, much like the plant's leaves.
