Oxalis triangularis grows from corms (also called "bulbils" [4]), propagated by division. Like other corms, it goes through regular dormancy periods; at the end of each period, the corms can be unearthed, offsets cut and replanted in appropriate soil, where they will grow into new plants. [10]
Photonastic movement of Oxalis triangularis in response to light. At lowered light levels the leaves fold down; timelapse recorded at ~750x actual speed and covering a 1.5 hr period of time.

Oxalis triangularis. Several species are grown as pot plants or as ornamental plants in gardens, for example, O. versicolor. Oxalis flowers range in colour from whites to yellow, peaches, pink, or multi-coloured flowers. [11] Some varieties have double flowers, for example the double form of O. compressus.
Dormancy should not be confused with seed coat dormancy, external dormancy, or hardheadedness, which is caused by the presence of a hard seed covering or seed coat that prevents water and oxygen from reaching and activating the embryo. It is a physical barrier to germination, not a true form of dormancy (Quinliven, 1971; Quinliven and Nichol ...
Original - Oxalis triangularis (also known as the love plant or purple shamrock) is a classic example of a plant which responds with movement to an external stimulus. The leaves open and close in response to varying light levels with the result that they are open during during the day and close at night.
The following species in the flowering plant genus Oxalis, many of which are called wood sorrels, wood‑sorrels or woodsorrels, false shamrocks, and sourgrasses, are recognised by Plants of the World Online: [1] [2]
In botany, a bulb is a short underground stem with fleshy leaves or leaf bases [1] that function as food storage organs during dormancy. In gardening, plants with other kinds of storage organ are also called ornamental bulbous plants or just bulbs.
Dormancy caused by an impermeable seed coat is known as physical dormancy. Physical dormancy is the result of impermeable layer(s) that develops during maturation and drying of the seed or fruit. [12] This impermeable layer prevents the seed from taking up water or gases. As a result, the seed is prevented from germinating until dormancy is broken.
