Overview
Oxalis spiralis G. Don is a perennial plant species that belongs to the family Oxalidaceae. It is native to South America and is commonly found in countries such as Brazil, Argentina, and Uruguay. It is also known by various common names, including "Creeping Oxalis", "Cape Sorrel", and "False Shamrock".
Appearance
The plant has a creeping habit and produces stems that are thin and wiry. They are covered in small, heart-shaped leaves that are green in color and have a glossy texture. The leaves are trifoliate, which means that they are composed of three leaflets, each measuring around 1 cm in length. The flowers of Oxalis spiralis G. Don are small and pink in color. They are borne on stalks that arise from the leaf axils.
Uses
Oxalis spiralis G. Don is generally used in South American traditional medicine to treat various ailments such as diarrhea, fever, and cough. It is also employed to treat urinary tract infections and to relieve pain. Additionally, the plant has horticultural significance and is grown as an ornamental plant in gardens. Its bright green foliage and delicate pink flowers make it an attractive addition to rock gardens, borders, and hanging baskets.
Light Conditions
Oxalis spiralis G. Don prefers bright indirect light or partial shade. Too much direct sunlight can cause the leaves to scorch. A south-facing window with sheer curtains or a shaded eastern or western exposure would be ideal for the plant. During the growth period, the plant requires 6 to 8 hours of bright light per day for optimal growth. However, during the flowering phase, it is better to keep the plant in a location with bright, indirect light, as too much direct light can cause the flowers to fade more quickly.
Temperature Requirements
The ideal temperature for Oxalis spiralis G. Don is between 60°F (15.5°C) and 75°F (24°C). The plant can tolerate temperatures between 50°F (10°C) and 85°F (29°C). However, sudden temperature fluctuations or extreme temperatures can cause the leaves to drop. During the winter months, it is essential to keep the plant away from cold drafts or excessively low temperatures.
Soil Requirements
Oxalis spiralis G. Don prefers well-draining soil with a pH between 5.5 and 6.5. A potting mix made of equal parts perlite, peat moss, and compost is ideal for the plant. The soil should be kept moist, but not waterlogged. Overwatering can lead to root rot, which can kill the plant. It's best to allow the top inch of soil to dry out between waterings.
Cultivation Methods
Oxalis spiralis G. Don, commonly known as the spiral sorrel, is a beautiful and unique plant that can be grown indoors or outdoors. To cultivate this plant, start by selecting a location that receives partial to full shade. Prepare the soil by adding compost or well-rotted manure and mix well. You can either propagate the plant by seeds or underground bulbs. Plant the bulbs or sow the seeds into the soil about 2 inches deep and 4 inches apart. Water the plant regularly and keep the soil moist but not waterlogged.
Watering Needs
Proper watering is crucial to the growth and development of Oxalis spiralis G. Don. This plant requires regular watering as it cannot tolerate drought conditions. However, be careful not to overwater as this can lead to waterlogging and root rot. Water the plant when the soil becomes dry to the touch. You can also mist the leaves occasionally to increase humidity around the plant.
Fertilization
Oxalis spiralis G. Don benefits from regular fertilization with a balanced fertilizer. You can either use a slow-release fertilizer or a liquid fertilizer. Feed the plant every two weeks during the growing season, which is spring and summer. Reduce fertilization during the dormant period, which is fall and winter.
Pruning
Pruning is not necessary for Oxalis spiralis G. Don. However, you can remove any dead or yellowing leaves to improve the appearance of the plant. You can also pinch back the tips of the plant to encourage bushier growth. Remove any flowers that have faded to prevent the plant from self-seeding.
Propagation of Oxalis Spiralis G. Don
Oxalis spiralis G. Don, also known as the curly sorrel or curly oxalis, can be propagated through different methods. The following methods are the most commonly used:
Seeds
The propagation of Oxalis spiralis through seeds is possible, but it is not the most common method used. To propagate using seeds, collect them from the plant and sow them in a well-draining soil mix, placing them at a depth of approximately 1/8 inch. Keep the soil moist, and germination can occur in 1 to 2 weeks in ideal conditions.
Cuttings
Propagation of Oxalis spiralis can be easily achieved using stem cuttings. Cut a healthy stem of approximately 3-4 inches from the parent plant and remove the leaves from the lower half of the cutting. Dip the cut end of the stem in a rooting hormone and plant it in a well-draining potting mix. Keep the soil moist and place the cutting in a location with bright but indirect sunlight. Roots should develop within a few weeks.
Division
Division is another method of propagating Oxalis spiralis. It involves separating the plant's root system into smaller sections and replanting them to create new plants. This method is best done in the spring when the plant is actively growing, divide the plant gently and remove any dead parts first. Once separated, plant each section in a well-draining soil mix and keep the soil moist, and place the plant in bright but indirect sunlight.
With these simple propagation methods, it's easy to propagate Oxalis spiralis and enjoy the beauty of this plant in your home or garden.
