Origin
Oxalis pulvinata Sond. is a plant species that belongs to the family of Oxalidaceae. The plant is native to Southern Africa and can be found growing in the Western Cape and Eastern Cape provinces of South Africa.
Common Names
Oxalis pulvinata Sond. is commonly known as cushion oxalis, cushion sorrel, or woolly oxalis. The name "cushion" refers to the plant's low-growing and compact habit, while "woolly" refers to the plant's hairy leaves and stems.
Uses
Oxalis pulvinata Sond. is commonly used as a groundcover in rock gardens, borders and edges of pathways, and containers. The plant's compact habit and attractive foliage make it an excellent choice for ornamental purposes. Additionally, the leaves of the plant are used as an herbal remedy for digestive disorders and as a natural source of vitamin C.
General Appearance
Oxalis pulvinata Sond. is a low-growing perennial plant that typically grows to a height of 10-15 cm. The plant produces a dense cushion of hairy, light-green leaves that are divided into three leaflets. The leaves are covered in fine hairs that give them a woolly texture. In the spring and summer, the plant produces pink or white flowers that are three to four centimeters in diameter. The flowers have five petals and are held above the foliage on slender stems.
Light Requirements
Oxalis pulvinata Sond. typically grows best in bright light to partial shade. It is adapted to growing in shaded or semi-shaded areas in the wild, but can also tolerate full sun if provided adequate water. As a general rule, it is best to provide bright, filtered light to avoid scorching the leaves or causing the plant to become leggy.
Temperature Requirements
This species is native to South Africa and prefers a mild to cool climate. It can tolerate some frost or freezing temperatures, but it is best to protect it from prolonged exposure to extreme cold. In warmer climates, it may require some extra care to prevent the soil from drying out or the plant from overheating. Ideally, temperatures should be kept between 50-75°F (10-24°C) for optimal growth.
Soil Requirements
Oxalis pulvinata Sond. is adapted to growing in well-draining soils that are rich in organic matter. It prefers a soil pH that is slightly acidic to neutral, between 6.0 and 7.0. The plant is not too fussy about soil type, but it does require good drainage to prevent the roots from becoming waterlogged. The addition of perlite or other amendments can be beneficial if soil drainage is poor. Watering should be done sparingly to avoid saturating the soil.
Cultivation Method
Oxalis pulvinata Sond. can be grown from seeds or by division. To grow from seeds, sow them in well-draining soil in a pot or directly in the garden bed. Cover the seeds with a thin layer of soil and keep them moist until they germinate. To grow from division, separate the plant clusters and plant them in a new location, making sure to keep the soil moist until they establish.
Watering Needs
Oxalis pulvinata Sond. requires a moderate amount of water, but make sure you don't overwater the plant. Overwatering can cause the roots to rot, which can eventually lead to the death of the plant. It's best to let the soil dry out a bit between watering to prevent this from happening. During hot, dry weather, you may need to water the plant more frequently to prevent the soil from drying out completely.
Fertilization
Oxalis pulvinata Sond. doesn't require a lot of fertilization, but it's beneficial to fertilize the plant once or twice a year with a balanced fertilizer. An organic fertilizer or compost is also a great option. Fertilize in the spring when the plant is beginning to grow, and again in late summer to promote bloom production.
Pruning
Oxalis pulvinata Sond. doesn't require much pruning, but you can trim back any dead or damaged foliage, or cut back the entire plant after it has finished blooming. If the plant is getting too leggy or has outgrown its space, you can also cut back the stems by up to one-third of their length to encourage new growth. Prune in the spring or summer, but avoid pruning in the fall or winter when new growth is minimal.
Propagation Methods of Oxalis pulvinata Sond.
Oxalis pulvinata Sond., commonly known as cushion oxalis, is a small, slow-growing succulent plant that belongs to the family Oxalidaceae. It is native to South Africa and is commonly used as a groundcover due to its tiny size and attractive foliage. If you wish to propagate Oxalis pulvinata Sond., there are several effective methods you can try.
Division
One of the easiest and most effective ways to propagate Oxalis pulvinata Sond. is through division. In early spring, carefully dig up the plant and separate it into several small pieces, making sure each section has some roots and stems. Plant each piece in a well-draining soil mix and keep it moist but not waterlogged. With proper care, each section should quickly establish roots and start to grow.
Cutting
Another method you can try is taking cuttings. Using a sharp, sterile knife, cut several healthy stems from the parent plant at an angle. Remove the lower leaves and dip the cut ends in rooting hormone to encourage rooting. Plant each cutting in a moist potting soil mix and cover it with a plastic bag to create a humid environment. Keep the soil consistently moist and in a warm, bright location, and roots should form within a few weeks.
Seed
Lastly, you can propagate Oxalis pulvinata Sond. from seed. Collect the seed pods when they turn brown and dry, then carefully open them to extract the seeds. Sow the seeds in a well-draining soil mix and lightly cover them with soil. Keep the soil consistently moist and in a warm, bright location. With proper care, the seeds should germinate within two to four weeks.
Propagation of Oxalis pulvinata Sond. is relatively easy and straightforward. By following these simple methods, you can propagate this lovely plant and enjoy its beauty in your home or garden.
