Oxalis crassipes 'Rosea' is also known as Wood Sorrel. It produces half-inch, fuchsia pink, flowers on fine stems that stand just above the attractive clover-like foliage. Oxalis 'Rosea' blooms in May-June, and again in September-October. Also sometimes known as Sweet Grass, its foliage is edible and has a distinct sweet taste. Interestingly, the leaves open during the day to receive sunlight but at night they fold up to look like a bouquet of little umbrellas.
Oxalis crassipes 'Rosea' prefers light or partial to mostly shade and moist, well-drained soil. It is drought tolerant once established. This bulbous perennial multiplies fairly quickly in good conditions.
