Oxalis triangularis, commonly called false shamrock, is a species of perennial plant in the family Oxalidaceae. It is native to several countries in southern South America . This woodsorrel is typically grown as a houseplant but can be grown outside in USDA climate zones 8a–11, preferably in light shade.
The flowers have five petals, which are usually fused at the base, and ten stamens. The petal color varies from white to pink, red or yellow; [ 6 ] anthocyanins and xanthophylls may be present or absent but are generally not both present together in significant quantities, meaning that few wood-sorrels have bright orange flowers.
The bulbs are produced to satisfy the demand for bulbs for parks, gardens and as house plants, in addition to providing the bulbs necessary for the production of cut flowers. The international trade in cut flowers has a worldwide value of approximately 11,000 million Euros, which gives an idea of the economic importance of this activity.
The shamrock carries religious ties, while the four-leaf clover is considered a sign of luck due to its exceeding rarity. In fact, around one out of 10,000 clovers have four leaves.

A diagram showing various parts of young O. stricta plants All parts of the plant are edible, [ 5 ] with a distinct tangy flavor (common to all plants in the genus Oxalis ). However, it should only be eaten in small quantities, since oxalic acid is an antinutrient and can inhibit the body's absorption supply of calcium.
Flowering plant bulbs are planted beneath the surface of the earth. The bulbs need some exposure to cold temperatures for 12 to 14 weeks in order to bloom. [1] Flower bulbs are generally planted in the fall in colder climates. The bulbs go dormant in the winter but they continue to absorb water and nutrients from the soil and they develop roots ...
