Overview
Xanthoxalis corniculata var. atropurpurea is a perennial plant that belongs to the Oxalidaceae family. It is a variety of Xanthoxalis corniculata and commonly referred to as Purple Oxalis.
Origin
The plant is native to the Americas, but it has now spread to other regions worldwide. It can be found in Asia, Europe, and Africa.
Common Names
Purple Oxalis is the most common name for Xanthoxalis corniculata var. atropurpurea. It is also known by other common names such as Creeping Wood Sorrel, Creeping Oxalis, and Sourgrass.
Appearance
Purple Oxalis has a unique appearance, characterized by its purple leaves and thready stems. The stems grow to a length of up to 30 cm and are covered with small hairs. The leaves are trifoliate; they have a heart-shaped base, and each leaflet is oval and measures around 1 cm. The plant produces small yellow flowers with five petals and a tubular, five-lobed calyx.
Uses
The leaves of Purple Oxalis have edible properties and are rich in Vitamin C. The plant is used in traditional medicine to treat fever, inflammation, and diarrhea. Additionally, it is a common ornamental plant, favored for its unique purple foliage.
Growth Conditions for Xanthoxalis corniculata
Xanthoxalis corniculata var. atropurpurea is a resilient and adaptable plant that can thrive in a wide variety of growing conditions.
Light
This plant prefers full sun to partial shade, and it will tolerate some shade. In hotter climates, it may benefit from some shade during the hottest part of the day. Inadequate light can cause the plant to grow tall and leggy, with fewer leaves and flowers.
Temperature
Xanthoxalis corniculata var. atropurpurea is a warm-season plant that prefers temperatures between 60°F and 80°F. It can tolerate temperatures down to 50°F but may begin to suffer if temperatures consistently drop below this range. Similarly, temperatures above 90°F can cause stress to the plant.
Soil
This plant is adaptable to a wide range of soil types, but prefers well-draining soil that is rich in organic matter. It can tolerate soils that are slightly acidic to slightly alkaline, with a pH range of 5.5 to 7.5. It also benefits from regular fertilization, although care should be taken not to over-fertilize.
Cultivation of Xanthoxalis corniculata (L.) Small var. atropurpurea (Planch.) Moldenke
Xanthoxalis corniculata (L.) Small var. atropurpurea (Planch.) Moldenke, commonly known as purple woodsorrel or creeping woodsorrel, is a hardy, perennial plant that is native to North America. It thrives in a variety of soil types and is suitable for cultivation in USDA hardiness zones 3 through 10. Here are some tips for cultivating purple woodsorrel:
Watering Needs
Purple woodsorrel prefers moist but well-draining soil. Water the plant thoroughly once a week, or more frequently if the soil is dry to the touch. Avoid overwatering, as this can lead to root rot.
Fertilization
Apply a balanced, all-purpose fertilizer to purple woodsorrel in the spring and again in mid-summer. Follow the package instructions for application rates, as over-fertilization can damage the plant.
Pruning
Purple woodsorrel benefits from occasional pruning to encourage bushier growth and prevent the plant from becoming too leggy. Prune back any dead or damaged foliage, and trim back any stems that have grown too long. Use sharp, sterile pruning shears to avoid damaging the plant.
Propagation of Xanthoxalis Corniculata (L.) Small Var. Atropurpurea (Planch.) Moldenke
Xanthoxalis Corniculata (L.) Small Var. Atropurpurea (Planch.) Moldenke, commonly known as Purple Oxalis or Creeping Woodsorrel is propagated by three main methods:
1. Seeds:
The plant produces small seeds that may be collected after the seed pods have ripened. Once collected, the seeds should be stored in a cool and dry place to maintain their viability. Sowing can be done in flats, pots or directly in the garden bed. The soil needs to be damp but not waterlogged. Sow the seeds thinly and cover with a thin layer of soil.
It is recommended to sow in the springtime when the temperature is above 60 degrees Fahrenheit. Seed germination usually takes 1-2 weeks.
2. Division:
Xanthoxalis Corniculata (L.) Small Var. Atropurpurea (Planch.) Moldenke can also be propagated through division. The clumps can be dug up, and the rhizomes separated. Sections that have been cut should be replanted immediately, ensuring that each new plant has an adequate amount of stem and root.
This form of propagation is best done in the spring or fall season.
3. Cuttings:
Xanthoxalis Corniculata (L.) Small Var. Atropurpurea (Planch.) Moldenke can be propagated through stem cuttings. Ideally, cuttings should be taken in spring, using sharp and sterile scissors. Cuttings of about 2-3 inches in length can be cut below a leaf node, then dried for a few hours before planting.
Dip the cuttings in rooting hormone before planting in a shallow container filled with potting mix. Water the cuttings moderately to encourage root growth.
Propagation through cuttings is usually a faster method of propagation and can provide results in just a few weeks.
Disease and Pest Management for Xanthoxalis corniculata (L.) Small var. atropurpurea (Planch.) Moldenke
Managing diseases and pests is crucial for the growth and survival of Xanthoxalis corniculata. Prevention is the key to avoid damage to the plant, but if detected, it is important to take action as soon as possible.
Common diseases
Xanthoxalis corniculata is typically not highly susceptible to diseases. However, potential problems include:
- Bacterial leaf spot: A common bacterial disease that causes small, angular, water-soaked lesions on the leaves. Over time, the lesions will turn yellow and the affected leaves may drop. To control the disease, remove any infected plants and reduce overhead watering.
- Powdery mildew: A fungal disease that produces white, powdery spots on the leaves, stems, and flowers. Preventative actions such as planting in well-draining soil, avoiding overhead watering, and providing adequate air circulation can help to avoid powdery mildew.
Common pests
Xanthoxalis corniculata is also commonly attacked by pests. Some of the pests that can cause damage to the plant include:
- Aphids: Aphids are small, pear-shaped insects that feed on the sap of the plant and cause wilting, yellowing, and leaf curling. To control aphids, consider releasing predatory insects such as ladybugs and lacewings or applying insecticidal soap.
- Spider mites: Spider mites are tiny, eight-legged pests that suck the sap from leaves and stems. They can cause yellowing, leaf curling, and defoliation. To control spider mites, keep the plant well-hydrated and out of direct sunlight.
It is important to monitor the plant regularly for any signs of disease or pest infestations. Catching the problem early and taking action to manage it can help protect the plant and promote healthy growth.
