Overview
Oxalis fontana Bunge var. fontana, also known as common yellow oxalis, is a perennial plant species that is native to Eurasia, but has naturalized in several parts of the world, including North America, South America, Africa, and New Zealand. This plant is commonly found in disturbed areas, open fields, lawns, and gardens. It is a member of the family Oxalidaceae, which includes more than 800 species of herbs, shrubs, and trees.
General Appearance
The common yellow oxalis is a low-growing plant that typically reaches a height of around 15 cm. It has a fibrous root system and a basal rosette of leaves. The leaves are trifoliate, which means they have three leaflets, and they are heart-shaped with wavy margins. Each leaflet is typically around 1-2 cm wide and 2-3 cm long. The leaves and stems of the plant are hairless and have a bright green color.
The flowers of the common yellow oxalis are bright yellow or pale yellow with five petals. They bloom from late spring to early fall and are borne on long, slender stalks that emerge from the center of the rosette. The flowers are about 1-1.5 cm in diameter and have a distinctive funnel shape. After flowering, the plant produces small capsules that contain several small, black seeds.
Common Names
The common yellow oxalis is known by several common names, including yellow wood sorrel, lemon clover, buttercup oxalis, and sourgrass. These names reflect the plant's yellow flowers, clover-like leaves, and its ability to produce a sour juice when its leaves or stem are crushed.
Uses
The common yellow oxalis has several traditional medicinal uses. The leaves and stems of the plant have a high concentration of vitamin C, which makes them useful in preventing scurvy. The plant also contains oxalic acid, which has been used to treat kidney stones by dissolving them. However, oxalic acid can also cause health problems if consumed in large quantities, so caution is advised.
The common yellow oxalis is also used as a food source in certain parts of the world. The leaves and stems can be added to salads, soups, and stews, and they have a tangy, lemony flavor. However, the plant should be consumed in moderation, as it contains oxalic acid, which can interfere with the absorption of calcium and other nutrients in the body.
Light Requirements
Oxalis fontana Bunge var. fontana thrives in bright, indirect light but can also tolerate some shade. This plant, like most indoor plants, should not be exposed to direct sunlight as it can burn its leaves. However, too little light may cause the plant to become weak and leggy, so it is best to keep it near a bright window or under grow lights.
Temperature Requirements
The ideal temperature for Oxalis fontana Bunge var. fontana is between 60°F and 75°F (15°C to 24°C). This plant can tolerate slightly lower temperatures for short periods but cannot survive in extreme temperatures. Avoid sudden temperature changes and keep it away from cold drafts or heat sources such as radiators and air conditioning vents.
Soil Requirements
Oxalis fontana Bunge var. fontana prefers moist, well-draining soil that is rich in organic matter. A mix of peat moss, sand, and perlite is excellent for this plant. The soil's pH should ideally be neutral to slightly acidic, with a pH range of 6.0 to 7.0. To avoid root rot, do not allow the soil to become waterlogged and ensure proper drainage by using a pot with drainage holes.
Cultivation Methods
Oxalis fontana Bunge var. fontana is a perennial herbaceous plant that prefers moist soil with high organic content and good drainage. It requires moderate to full sunlight and grows well in both shady and sunny locations. It is propagated by seeds, bulbs, or division of the rootstock.
If you are growing oxalis from seed, sow them in a well-draining potting mix and keep the soil moist, but never waterlogged. As the plants grow, repot them into larger pots or containers. If you are propagating by division, split the plant into sections with at least one healthy bulb, replant each section in fresh potting soil, and water well.
Watering Needs
Oxalis fontana Bunge var. fontana prefers moist to slightly dry soil. It is essential to water regularly, especially during the growing season. However, avoid overwatering, as it may cause root rot. To ensure that the soil is moist, but not waterlogged, water the plants deeply once a week, or more frequently, depending on the temperature and humidity levels. Check the soil moisture level by poking your finger into the soil. If it feels dry an inch below the surface, it is time to water again.
Fertilization
Feed Oxalis fontana Bunge var. fontana with a balanced liquid fertilizer every two weeks during the growing season, from spring to early fall. Make sure to dilute the fertilizer according to the package instructions and apply it to the soil, not the leaves. Stop fertilizing during the winter dormancy period. Over-fertilization may lead to root burn and damage to the plant, so always follow the recommended dosage.
Pruning
Oxalis fontana Bunge var. fontana does not require regular pruning. However, you can remove any yellow or dead leaves, stems, or flowers as soon as you notice them, to maintain the plant's aesthetic appeal. It will also help to prevent the spread of any diseases or pests. Prune the plant after the flowering season to encourage healthy growth and a more compact shape. Use clean, sharp scissors, or pruning shears to avoid damaging the plant.
Propagation of Oxalis Fontana Bunge var. Fontana
Oxalis Fontana Bunge var. Fontana, commonly known as Wood Sorrel, is a low-growing, perennial plant that belongs to the family Oxalidaceae. It is native to Asia and Europe and is valued for its ornamental foliage and delicate flowers. Propagation of Oxalis Fontana Bunge var. Fontana can be done either vegetatively or by seeds.
Propagation by seeds
Propagation of Oxalis Fontana Bunge var. Fontana by seeds is relatively easy. Collect the seeds from the mature plant with a tweezer and plant them in a well-draining soil mix. Cover the seeds with a thin layer of soil and water them. Maintain the moisture level by adding water whenever necessary, and place the pot in a warm and bright location. The seeds typically germinate within two to three weeks.
Propagation by Vegetative Methods
Propagation of Oxalis Fontana Bunge var. Fontana by vegetative methods can be done through stem cuttings or division.
Propagation by Stem Cuttings
To propagate Oxalis Fontana Bunge var. Fontana by stem cuttings, start by selecting a healthy stem from an existing plant that has at least two nodes. Cut the stem at a 45-degree angle with a sharp and sterile knife. Dip the cut end in a rooting hormone powder and plant it in a well-draining soil mix. Keep the soil lightly moist and cover the pot with plastic to maintain humidity. Rooting should occur in two to three weeks, after which you can remove the plastic.
Propagation by Division
For propagation of Oxalis Fontana Bunge var. Fontana by division, start by carefully digging up the plant and gently separating it into smaller sections. Each section should have its own roots and foliage. Replant the sections in separate pots with well-draining soil mix, water them, and place them in a warm and bright location. With proper care, the sections will establish in their new pots within a few weeks.
