Overview of Oxalis lasiandra
Oxalis lasiandra is a flowering plant that comes from the Oxalidaceae family, also known as the wood sorrel family. Native to South Africa, this plant is known by various common names, including lavender oxalis, purple wood sorrel, and African wood sorrel. The plant is commonly grown as an ornamental plant and has distinctive bright purple-pink flowers.
Appearance of Oxalis lasiandra
Oxalis lasiandra is a small herbaceous plant that typically grows to a height of around 10 to 20cm. The plant has clover-like leaves that are typically green in color. The leaves can be quite variable, with some leaves having a delicate feathery appearance, while others are broader and more solid in appearance. The leaves are arranged in a rosette at the base of the plant and are typically around 2-5 cm long.
The flowers of Oxalis lasiandra are the most distinctive feature of the plant. The flowers are trumpet-shaped and have five petals. The flowers are bright purple-pink in color and are typically around 2-3 cm in diameter. The flowers are borne in clusters at the end of thin stems that rise above the leaves.
Uses of Oxalis lasiandra
Oxalis lasiandra is primarily grown as an ornamental plant for its attractive flowers and foliage. The plant is suitable for growing in pots, containers, and hanging baskets, and can also be used as a ground cover in sunny areas. The plants can be propagated by division and can grow in a wide range of soil types, from sandy to clay soils, as long as the soil is well-draining.
In traditional medicine, Oxalis lasiandra has been used to treat a variety of ailments. The plant is known to have high levels of antioxidants, which may help to protect against free radical damage. The plant has also been used to treat conditions such as stomach ulcers, skin rashes, and respiratory infections. However, more research is needed to verify these claims and to identify the active compounds responsible for these potential health benefits.
Light Requirements
The Oxalis lasiandra plant prefers to grow in partial shade to full sun exposure. It thrives when it receives 4 to 6 hours of direct sunlight per day, but too much exposure to direct sunlight may cause its leaves to wilt or burn. Therefore, it is advisable to place it in a location with filtered sunlight or partial shade for optimal growth.
Temperature Requirements
The optimal temperature range for the Oxalis lasiandra plant is between 60 to 75°F (15 to 24°C). The plant may not thrive in hot or cold climates, so it is advisable to protect the plant from extreme temperatures and keep it in a moderately cool environment. Temperatures above 85°F (29°C) may cause the plant to go dormant, whereas temperatures below 50°F (10°C) may result in the plant's leaves turning yellow or dropping off.
Soil Requirements
The Oxalis lasiandra plant requires well-draining soil that is rich in organic matter. The soil should be moist but not waterlogged as the plant is susceptible to root rot. A pH range between 6.0 to 7.5 is optimal for the plant's growth; thus, it is advisable to supplement the soil with organic fertilizers to ensure the plant receives sufficient nutrients. Adding sand or perlite to the soil can aid in improving drainage and aeration, enabling the plant to grow healthily.
Cultivation methods
Oxalis lasiandra is best grown in well-draining soil that is slightly acidic. The plant prefers to be grown in a partially shaded area that still gets a good amount of sunlight.
If being grown indoors, it is best to place the plant in a south-facing window that gets bright indirect sunlight. The plant does not do well in direct sunlight and can easily burn if left in the sun for too long.
When planting outside, make sure to space Oxalis lasiandra about 6 inches apart to allow enough room for proper growth. The plant grows to be about 8-10 inches tall and has a spread of around 12 inches.
Watering needs
The plant prefers to be kept moist but not overly wet. It is essential to water the plant regularly and keep the soil slightly damp. Make sure not to overwater, as too much moisture can lead to root rot and other fungal diseases.
When growing indoors, it is best to avoid getting water on the leaves to prevent spotting and other damage to the plant.
Fertilisation
It is beneficial to fertilize Oxalis lasiandra every 2-3 months. For the best results, use a well-balanced fertilizer that is water-soluble. When fertilizing, make sure to follow the instructions on the package to avoid over-fertilizing, which can harm the plant.
During the winter months, it is best to avoid fertilizing the plant as it enters a dormant phase.
Pruning
Oxalis lasiandra does not require regular pruning, but it is beneficial to cut back any dead or dying leaves to promote healthy growth. Trimming back the plant occasionally can also help keep it looking full and bushy.
If the plant becomes too large, it can be divided into smaller sections and replanted. This will not only allow for better growth and healthier plants but more plants to enjoy in other areas of the garden or for gifting to loved ones.
Propagation of Oxalis Lasiandra
Oxalis lasiandra is commonly known as the dusty pink wood sorrel. It is a perennial plant that belongs to the Oxalidaceae family. The plant is found mainly in South Africa. Oxalis lasiandra is a beautiful plant that produces pink or white flowers. It is possible to propagate Oxalis lasiandra through various methods.
Division
Division is an excellent method of propagation of Oxalis Lasiandra. It involves dividing the existing plant to produce new ones. To propagate by division, gently remove the plant from the soil. Gently separate the root ball into two or three portions. Each portion should have roots and shoots. Plant each portion in a pot or in the ground.
Seed Germination
Seed germination is another method of propagating Oxalis lasiandra. Collect the seeds when the plant is in its flowering stage. The seeds should be planted in a well-draining soil mixture. Keep the soil moist and warm. Germination should occur within two to three weeks. Once the seedlings grow to a reasonable size, they can be transplanted into individual pots or directly into the ground.
Leaf Cuttings
Leaf cuttings are another method of propagating Oxalis lasiandra. This technique is ideal, especially during the winter months when the plant is dormant. Select healthy leaves from the parent plant. Cut the stem at an angle of 45 degrees. Dip the cut end in rooting hormone, then plant in a well-draining soil mixture. Keep the soil moist, and new shoots should appear in 6 to 8 weeks.
Bulbils
Bulbils are small bulblets that grow on the stem of the plant. They can be removed and planted. Once removed, plant them in a well-draining soil mixture and keep the soil moist. The bulbils should develop into full plants with time.
In conclusion, Oxalis lasiandra can be propagated through division, seed germination, leaf cuttings, and bulbils. These methods are suitable and should produce healthy plants.
Disease and Pest Management for Oxalis Lasiandra
Oxalis Lasiandra is a beautiful plant with triangular leaves and pink flowers, which can make a perfect addition to any garden. However, like any plant, it is susceptible to diseases and pests that can weaken or kill it.
Common Diseases

To manage them, you can spray the plant with a strong jet of water, use insecticidal soap, or introduce natural predators like ladybugs.
Spider mites are another pest that can attack this plant, resulting in yellow leaves and webs between the stems. To manage them, you can increase humidity around the plant, remove affected leaves, and use miticides.
Prevention Measures
To prevent diseases and pests from attacking your Oxalis Lasiandra, it is important to keep the plant healthy by providing it with proper care. This includes watering it regularly but avoiding waterlogging, fertilizing it with a balanced fertilizer, and pruning it regularly to remove dead or diseased parts.
