Oxalis is a genus of plants in the family Oxalidaceae, consisting of over 900 species of annual and perennial herbs, shrubs, and small trees. Many species are cultivated as ornamental plants for their attractive foliage and delicate flowers.
Oxalis plants have characteristic trifoliate leaves, which means each leaf is divided into three leaflets. The leaves are usually heart-shaped or clover-like and can range in color from green to purple or red. The flowers of Oxalis plants are also unique and come in a variety of colors, including white, yellow, pink, and purple. They typically have five petals and a distinctive tubular shape.
Oxalis plants can be grown both indoors and outdoors, depending on the species. They prefer bright, indirect light and well-draining soil. Some species are dormant during the winter months and should be allowed to dry out between watering, while others are evergreen and require more frequent watering. Oxalis plants can also be propagated by dividing the roots or by planting bulbils that form on the stem or leaves.
While Oxalis plants are generally easy to care for, they can sometimes be considered invasive in some areas and may require special attention to prevent them from spreading too aggressively. Overall, they are a popular choice for gardeners and indoor plant enthusiasts due to their attractive foliage and unique flowers.
