Sour Clover, also known as Oxalis or wood sorrel, is a small plant characterized by its clover-like leaves and yellow or white flowers. It typically grows in grassy areas and is often found in gardens and meadows. The leaves are heart-shaped and can be mistaken for those of true clover, but they have a distinct sour taste due to the presence of oxalic acid. This plant is often considered a weed, but it has edible parts that can be used in salads or as a flavoring. Sour Clover is also known for its ability to thrive in various soil types and can spread quickly, making it a resilient addition to many ecosystems.
