Oxalis vulcanicola ‘Burgundy’: Purple Shamrock

Shamrock leaf shape in a deep burgundy hue. A semi trailing form is wonderful for containers or a shady window box. Yellow flowers contrast strikingly well with the burgundy foliage.

Oxalis

Oxalis is the largest genus [800] in the wood-sorrel family Oxalidaceae [approximately 900 known species]. The genus occurs throughout most of the world, except for the polar areas; species diversity is particularly rich in tropical Brazil, Mexico and South Africa.

Many of the species are known as wood sorrels as they have an acidic taste reminiscent of the unrelated sorrel proper [Rumex acetosa]. Some species are called yellow sorrels or pink sorrels after the color of their flowers instead. Other species are colloquially known as false shamrocks, and some called sourgrasses.
