Oxalis triangularis Amber

The Oxalis triangularis 'Amber' is a pretty variety with green leaves and pink flowers, derived from the Purple Shamrock, a small frost-tender bulbous plant often used for interior decoration. Its giant clover-like foliage, as decorative as it is amusing, follows the light and charmingly folds up in the evening. Its small fresh pink flowers bloom for a long period, from spring to summer. An elegant, architectural, and original indoor plant, this oxalis can be placed outside during the warmer months, in a semi-shaded spot (only morning sun) that is cool. Indoors, position it in bright light, but not in direct sunlight.

The Oxalis triangularis ssp. papilionaceae 'Amber' belongs to the Oxalidaceae family. Its wild ancestor is widespread in several countries in South America such as Argentina, Brazil, Bolivia, and Paraguay. It is a herbaceous plant that grows from a tuberised rhizome. The vegetation emerges from the soil in spring and disappears in winter, which corresponds to its resting period. In winter, the plant should not be watered. The plant reaches approximately 15 cm in height. Without stems, it develops leaves carried by a long petiole emerging directly from the rhizome. The leaf is divided into 3 generally triangular leaflets, slightly notched, arranged in the same plane perpendicular to the petiole. The leaves orient themselves following the light: they close around the petiole in the evening and spread out at sunrise. The flowering period is long, from May-June to July-August, even extending to September. It takes the form of umbels carried by a long petiole. Each umbel bears 2 to 9 small funnel-shaped flowers expanding into 5 rounded lobes.

Oxalis, often perennial, with bulbous or rhizomatous roots, remain relatively unknown despite their generous flowering and numerous possibilities for use. Not all varieties are invasive, quite the opposite. They are an ideal choice for gardeners seeking originality. The Oxalis triangularis 'Amber' is showcased in hanging baskets or flower pots, always sheltered from intense sunlight. Very trendy, this small plant fits perfectly in a contemporary interior.
