Characteristics of the plant
Oxalis Triangularis is a rustic rhizomatous plant , known for its trifoliate leaves of an intense purple color. Native to South America, this plant can be grown both indoors and outdoors, adapting to various climatic conditions.
Origins and original habitat
Oxalis Triangularis is native to South America , where it grows in subtropical environments. In nature, it can be found mainly in Brazil , in regions with a humid and moderately warm climate. This plant is accustomed to living under the cover of taller vegetation, receiving indirect light filtered through the leaves of the trees. The natural environment of Oxalis Triangularis is characterized by well-draining, moist soils rich in organic matter , which allow the rhizomes to thrive.
Purple Color: Natural or Man-Made Species?
Oxalis Triangularis is a naturally occurring species and its characteristic purple color is not the result of genetic manipulation in a laboratory. The deep purple leaves are one of the distinctive characteristics of the plant, and this coloration is due to the presence of anthocyanins, natural pigments that protect the plant from damage caused by intense sunlight. This attractive coloration is one of the reasons why Oxalis Triangularis is highly appreciated by both gardening enthusiasts and professionals in the sector.
The nyctinasty of Oxalis Triangularis
Oxalis Triangularis, known for its beautiful purple, triangular-shaped leaves, is a plant that displays a fascinating behavior called nyctinasty.
This phenomenon is manifested through the movements of leaves in response to changes in light between day and night. During the day, leaves spread out to maximize photosynthesis. At night, however, leaves close, a strategy that helps the plant reduce heat loss and conserve energy.
This movement is regulated by changes in the turgor pressure of the motor cells located at the base of the leaves, which absorb and release water in response to light. Nyctinasty not only protects the plant from low night temperatures, but also from potential predators and pathogens, making Oxalis Triangularis an extremely adaptable and resilient plant.
The result of this phenomenon is a beautiful, slow dance of the leaves throughout the day, opening and closing like the wings of a butterfly.
The plant "shoots seeds"
In addition to its fascinating nyctinasty, Oxalis Triangularis, like other Oxalis varieties, has another interesting mechanism: explosive dehiscence. This phenomenon allows the plant to shoot seeds away from the mother plant. As the fruits ripen and dry, they build up tension in the fruit walls until they explode, launching the seeds some distance away.
This dispersal strategy allows Oxalis Triangularis to colonize new areas, improving its chances of survival and reproduction in different environments. Explosive dehiscence is a further example of the extraordinary adaptability of this plant.
Difference between Oxalis Triangularis and the variety 'Mijke'
Oxalis Triangularis and its variety 'Mijke' are both highly decorative plants, but have some notable distinctions.
Oxalis Triangularis is characterized by light pink flowers and purple-brown and reddish leaves that close at sunset. This species is sufficiently rustic to survive during the winter in common Italian conditions.
The variety 'Mijke' , on the other hand, is an interesting selection of Oxalis Triangularis, with leaves of a uniform dark purple-reddish color, without the dark patterns on the petals. The flowers of 'Mijke' are a more intense pink, more in the lilac tone. This cultivar offers a significant aesthetic contribution and is well suited to growing in pots or bowls due to its uniform and attractive color.
Ideal temperature
The ideal temperature for Oxalis Triangularis varies between 15-25°C, which allows the plant to maintain continuous vegetation. However, it can withstand lower temperatures, even slightly below zero. During the cold months, the plant may lose its leaves, but the rhizomes remain alive in the soil and the vegetation reappears with the arrival of spring.
Light and positioning
Oxalis Triangularis thrives in bright indirect light . It is important to avoid direct sunlight to prevent leaf scorch. The ideal location is near east or west facing windows where it can receive filtered light.
Watering
This plant requires moderate watering . It is essential to let the soil dry slightly between waterings to avoid water stagnation, which could cause root rot. Oxalis is not particularly demanding in terms of humidity, tolerating the home environment well.
Soil and pot
Oxalis Triangularis prefers well-draining, light and airy soil, similar to that used for houseplants. It is advisable to use a pot with drainage holes, preferably plastic or terracotta, to ensure good water flow and prevent stagnation.
Fertilization
During the growing season , which runs from spring to summer, Oxalis Triangularis benefits from regular fertilization. It is recommended to use a balanced liquid fertilizer every four weeks to ensure a constant supply of nutrients.
Other characteristics and growing tips
Oxalis Triangularis can be grown both in pots and in the open ground. Outdoors, it is important to protect the pots from intense frost and, if planted in the open ground, mulch to protect the rhizomes and roots from the cold.
Conclusion
If you want to add a touch of color and liveliness to your home, Oxalis Triangularis is the ideal choice. Its purple leaves and ease of cultivation make it perfect for both beginners and experienced gardeners. Its leaves are colorful but at the same time elegant and its lilac flowers are a real love for the eyes!
