Oxalis aka Wood Sorrel

Taxonomy

Oxalis is a large genus of flowering plants in the wood-sorrel family Oxalidaceae, consisting of over 550 species. Found throughout most of the world, excluding polar areas, the genus exhibits a high species diversity, particularly in tropical Brazil, Mexico, and South Africa. Commonly referred to as wood sorrels, these plants have an acidic taste resembling sorrel proper, although they are distantly related. Some species are known as yellow sorrels or pink sorrels, named after the color of their flowers. Other colloquial names include false shamrocks and sourgrasses. Additionally, the term oxalises is used to refer to the entire genus. One specific species is a clump-forming, bulbous perennial that grows up to 25cm tall when in flower. It features dark velvet clover-like leaves with triangular leaflets and slender stems bearing funnel-shaped, white flowers in umbels above the foliage during late spring and summer. Another striking variety, suitable for miniature gardens, displays colorful foliage with dark purple maroon leaves adorned with bright pink splashes. This compact plant produces small, yellow flowers throughout the year and can thrive in both sunny and shaded conditions. Its variegated leaves create a beautiful contrast and make it an excellent choice for mixing with succulents.
