The species is distributed in several countries of South America: Brazil, Bolivia, Argentina and Paraguay. It is a neophyte in the United States in the states of Florida and Louisiana. It is also widely found in East India abundantly in states like Nagaland and Manipur.
Cultivation and life cycle
O. triangularis requires bright indirect sunlight supplemented with a cool indoor temperature of 15 °C (59 °F). It can tolerate higher indoor temperatures but will go into dormancy prematurely and/or begin to take on a "tired" appearance if temperatures exceed 27 °C (81 °F) for prolonged periods of time. It thrives in an average potting soil with good drainage.
Mature plants are cut back to the soil every 3–5 years in early summer or during the dormancy period. Young plants are cut back to the soil every year in early summer or during the dormancy period, until they reach maturity. Fearing frost, they are usually grown indoors. They are planted in soil rich in humus and well drained. They should be watered only when the topsoil looks dry. In winter, they should not be watered.[3] The main difficulty in caring for frost-resistant oxalises is to prevent them from growing uncontrollably.[4] The ripe fruit of the plant will crack, throwing away seeds over a considerable distance, so do not plant the oxalis close to vegetable beds. Oxalis need no fertilizer before flowering. Afterwards it can be fertilised with an appropriate fertiliser. Plants usually only need nitrogen whereas phosphorus, potassium and easily absorbed trace elements help them to flower long and beautifully.[5] When growing in a flowerbed,[6] it is also worth feeding oxalis during the flowering period with a small dose of a multi-component fertiliser.[7]
The subspecies Oxalis triangularis subsp papilionacea has won the Royal Horticultural Society's Award of Garden Merit.[8]
