Oxalis spiralis, also known as African clover or butterfly plant, is one of the most prized species in gardening and interior design for its unique beauty and ease of cultivation. This article offers a comprehensive and practical guide to its characteristics and care, incorporating all relevant and up-to-date information so you can enjoy a healthy, attractive, and long-lasting plant both at home and in the garden.
Full description of Oxalis spiralis
Oxalis spiralis is a small perennial plant, generally does not exceed 15 or 20 centimeters in height, although it can reach up to 30 centimeters in extension if grown in optimal conditions and in suitable environments.
- Leaves: It has trifoliate, heart-shaped leaves in shades ranging from bright green to purple or even pink or variegated hues. These leaves are its main attraction and fold or unfold depending on the light, creating a dynamic, almost "living" effect.
- Tallos: The stems are usually thin and reddish in color, supporting both the foliage and the flowers.
- FloresThe five-petaled flowers are small but numerous. They are predominantly yellow, although they can vary and come in shades of white, pink, or purple depending on the variety. Flowering extends from spring and, in suitable environments, can continue into autumn.
Photonastic behaviorOne of the most notable characteristics of Oxalis spiralis is its response to light. During the day, the leaves open to better capture sunlight, and at night or in the absence of sunlight, they fold, simulating the plant's "sleep." Thus, the plant appears to change shape and appearance throughout the day.
In addition, it can bend its leaves towards areas where it receives more light, actively adapting to its environment. This property makes it especially attractive for those who enjoy observing the "reactions" of their plants.
Origin and distributionAlthough it has become popular worldwide, Oxalis spiralis is native to South Africa, especially the Cape Province. It is known for its adaptability and resilience to a wide variety of conditions, although it prefers temperate environments.
Location, temperature and light exposure
Oxalis spiralis is suitable for both indoor and outdoor spaces, although its ideal location will depend on the local climate. Outdoors, it can be used in rockeries, flowerbeds, flower beds, groundcovers, and along paths, adding a very interesting touch of color and texture. Indoors, it looks especially good in hanging pots, on well-lit terraces and balconies.
- Luz: Requires abundant ambient light. It thrives in direct sunlight in the morning or late afternoon, although it's best to avoid strong midday sun in hot climates to avoid damaging the foliage. For more information on how to care for flowering indoor plants, visit flowering indoor plants.
- TemperatureThe optimal temperature for Oxalis spiralis is between 15 and 25°C. It can tolerate heat peaks of up to 30°C if the substrate is kept moist and there is partial shade. Below 5°C, the plant goes dormant and the foliage may disappear, but the bulbs usually survive to sprout again in spring.
- Location according to climateIf you live in areas with cold winters, protect your Oxalis indoors or by mulching to prevent damage to the bulbs. If the summer is very hot, place it in partial shade.
This behavior, together with its easy acclimatization, allows it to be grown in a wide variety of environments, adapting without problem to urban or rural microclimates.
Substrate characteristics and soil type
The substrate is key to the success of growing Oxalis spiralis. It needs a loose, well-draining soil rich in organic matter., as roots and bulbs can easily rot if waterlogged. If you'd like to learn more about the types of soil suitable for growing them, we recommend visiting Oxalis deppei care.
- Ideal mix: Universal substrate mixed with perlite, river sand, or fine gravel (30%) to improve drainage. It's advisable to add mature compost, worm castings, or well-rotted manure to provide nutrients and keep the soil slightly moist.
- Optional step: In pots, check that they have drainage holes and add a bottom layer of gravel or expanded clay.
- pH: It tolerates substrates with acidic, neutral or slightly alkaline pH, which makes it easy to adapt to most gardens and pots.
To protect the bulbs in winter and maintain moisture, you can cover the surface of the substrate with pine bark or mulch.
Irrigation: how and when to do it
Watering is probably the most delicate aspect of caring for Oxalis spiralis.The soil should always be slightly moist, but never waterlogged. Excessive moisture encourages the growth of fungus and root rot, while prolonged drought quickly kills and withers the plant.
- In spring and summer, water 2 to 3 times a week, always checking that the top layer of soil begins to dry before watering again. For more information on watering frequency for flowering plants, visit plants with purple flowers.
- In fall and winter, reduce the amount of watering. If the plant goes dormant (due to cold weather), a light watering every 3 or 4 weeks will be sufficient.
- In summer or dry environments, Oxalis may need daily water as long as the substrate drains properly.
- Avoid over-wetting leaves and flowers during watering to prevent fungal diseases.
Observe the appearance of the leaves: if they look limp but the substrate is moist, reduce watering; if they are wilted and the substrate is dry, water more regularly.
Optimal fertilization and manure
Oxalis spiralis is a plant that actively demands nutrients during its growth and flowering period.Regular fertilization promotes the production of showy leaves and abundant blooms. For more details, please consult the most exotic flowers in the world.
- From early spring to late summer, apply organic liquid fertilizer or guano once every two weeks. If you prefer commercial fertilizers, choose a low-concentration fertilizer for flowering plants (diluted to half the recommended dosage for fragile plants).
- During transplanting, add compost or humus to the mix to promote rooting and recovery.
- In autumn and winter, suspend fertilization to allow the plant to rest.
Avoid excess nitrogen, which can promote leaf development but reduce flowering intensity. Fertilizers rich in potassium and phosphorus are preferable to promote flowers and the overall health of the bulbs.
Pruning and cleaning: essential maintenance
Oxalis spiralis does not require any specific pruning, but it is essential to clean the plant periodically.Removing dried leaves and flowers helps prevent pests, improves appearance, and encourages new blooms.
- Cut off any damaged or withered parts with clean, disinfected scissors.
- For plants grown outdoors or in hanging baskets, trim excessively long stems if you want to maintain a compact shape.
- Avoid pruning during active flowering or when the plant is dormant.
Most common pests and diseases
Although it is quite hardy, Oxalis spiralis can be affected by certain problems if basic care is neglected.
- PestsMites, whiteflies, and aphids can attack the plant, especially when it's too humid or in closed environments. Regular cleaning and the use of organic insecticides (neem oil, potassium soap) are usually sufficient for control. For specific pest control, consult biological control of the crystal mite.
- Fungi and rotOverwatering is the main enemy, promoting diseases such as botrytis or bulb and root rot. Always use well-draining substrates.
- Stress due to lack of lightOxalis loses vigor, leaves turn pale, and flowering is reduced if grown in excessive shade. Make sure to provide sufficient indirect light or a few hours of mild sun. For more information on diseases and pests, visit .
In case of severe infestations, remove the affected parts and isolate the plant to avoid contamination of other species.
Multiplication and propagation of Oxalis spiralis
Propagation of Oxalis spiralis is very simple and within the reach of any hobbyist.There are two main methods and one additional one for collectors:
- Division of bulbs or suckersRemove the plant from the pot or soil carefully, taking care not to damage the bulbs. Gently separate the lateral bulbs and plant them in fresh soil after letting the wounds dry for a few days to prevent infection. This is the safest and fastest method.
- Stem cuttings: Cut a healthy stem with at least one leaf and plant it in a moist substrate, maintaining high humidity and warm temperatures until it roots.
- By seedIf you want to experiment, you can collect the seeds after flowering and sow them in germination trays in spring.
Division should be done once a year, preferably just after flowering or after the dormant period, thus ensuring vigorous plants and controlling their spread, since in some places Oxalis can behave as an invasive species.
Suitable for indoor and outdoor use: usage ideas and special recommendations
The appeal of Oxalis spiralis lies in its adaptability and the visual impact it creates both in pots and in the open garden.Here are some ideas and tips to help you take advantage of its ornamental potential:
