Oxalis pes-caprae, more commonly known as Bermuda Buttercup, Sourgrass, or African Wood Sorrel.
Key Identification Features
* Flowers: Bright yellow, bell-shaped flowers with five petals that grow in clusters at the top of long, slender stems.
* Leaves: Deeply heart-shaped (obcordate) leaflets that grow in groups of three. You might notice small purple or brown spots on them, which is a common trait for this species.
* Stem: The stems are often slightly translucent and succulent.
Interesting Facts
* The "Sour" Taste: It's often called "Sourgrass" because the stems and leaves contain oxalic acid, giving them a sharp, tart flavor. While technically edible in small amounts, it's best to avoid consuming large quantities as the acid can interfere with calcium absorption.
* Invasive Nature: Native to South Africa, it has become a very successful (and sometimes frustrating) "weed" in places like California, Australia, and the Mediterranean. It spreads via tiny underground bulbs that are notoriously difficult to remove from garden soil.
* Light Sensitivity: You may notice the flowers and leaves "sleep" or fold up tightly at night or during very overcast weather.
