Oxalis is a genus of flowering plants commonly known as wood sorrels. They are characterized by their clover-like leaves and small, often brightly colored flowers. Many species are found in temperate regions, and they thrive in a variety of habitats, including gardens and forests. Some Oxalis species are edible and have a tangy flavor due to their oxalic acid content, which gives them a sour taste. However, excessive consumption can be harmful. These plants are also popular in ornamental gardening for their attractive foliage and flowers, making them a favorite among gardeners and landscapers.
