Oxalis triangularis 'Fanny' is a spectacular ornamental variety of wood sorrel with unusual dark purple triangular leaves and delicate light pink flowers. Elegant flowers on slender peduncles rise above the dense foliage, creating a light, airy cloud during flowering. A special feature of the plant is its ability to fold its leaves in the evening and unfold them with the first rays of the sun, which makes it particularly interesting for home cultivation. Wood sorrel is native to the tropical and subtropical regions of South America, primarily Brazil, where it grows in natural conditions. Thanks to the unusual shape of its leaves, resembling butterfly wings, and prolonged flowering, the plant quickly gained popularity among florists worldwide. The Fanny variety is valued for its compact form, abundant flowering, and high decorative appeal throughout the season. The plant prefers bright diffused light or light partial shade, loose nutritious soil, and moderate watering without waterlogging. It blooms from May to October, is perfectly suited for growing indoors, in winter gardens, on balconies and terraces, and in warm weather can adorn flowerbeds and container compositions.
