Common purslane (Portulaca oleracea) is a low-growing, succulent plant that thrives in warm climates. Often considered a weed, it is actually a versatile and nutritious plant with many culinary and medicinal uses.
In this article, we will delve into the world of common purslane, covering its uses, nutritional benefits, and how to grow it in your garden.
Scientific Classification and Naming
Common purslane belongs to the Portulacaceae family and is scientifically known as Portulaca oleracea. It is also known by various other names, such as verdolaga, pigweed, or little hogweed.
This is not the same plant as the one commonly known as “portulaca.” That plant has cylindrical, needle-shaped leaves, whereas purslane has rounded leaves.
Uses of Common Purslane
Common purslane has a long history of culinary use in various cultures. Its leaves and stems can be eaten raw in salads or cooked in soups, stews, and stir-fries. Its mild, slightly tangy flavor pairs well with various ingredients, and its succulent texture adds a unique crunch to dishes.

Historically, traditional medicine has used common purslane for its anti-inflammatory, analgesic, and antioxidant properties. Some studies suggest that it may help improve heart health, reduce inflammation, and boost the immune system. However, more research is needed to understand its potential medicinal benefits.
Common purslane is a nutritional powerhouse, containing high levels of vitamins A, C, and E and essential minerals like magnesium, calcium, and potassium. It also contains omega-3 fatty acids, which benefit heart health and brain function.
How to Grow Common Purslane
To grow common purslane in your garden, you can either plant seeds or propagate from cuttings. Sow seeds in the spring, after the risk of frost has passed, or plant cuttings directly in the soil.
Soil and Sunlight Requirements
Common purslane prefers well-draining soil and full sun exposure. However, it can also tolerate partial shade and less-than-ideal soil conditions, making it a low-maintenance plant suitable for beginner gardeners.
Watering and Fertilization
Purslane is drought-tolerant and does not require much water. Water the plant sparingly, allowing the soil to dry out between waterings. Too much water can lead to root rot. Fertilization is generally unnecessary, as purslane can grow well in nutrient-poor soils.
Pruning and Harvesting
Prune common purslane regularly to encourage bushy growth and prevent it from becoming too leggy. Pinch off the tips of the stems or remove any flowers to promote more leaf production. You can start harvesting leaves and stems once the plant reaches a height of about 4 inches. Harvest in the morning for the best flavor and to retain the most nutrients.
Common Purslane in the Garden
Common purslane can be a beneficial companion plant in the garden. Its low-growing habit and dense foliage help to suppress weeds, conserve soil moisture, and prevent soil erosion. Purslane can be grown alongside plants such as tomatoes, peppers, and cucumbers.
Pest and Disease Control
Common purslane is relatively pest- and disease-resistant. However, it can occasionally attract pests like aphids or whiteflies. Treat the affected plants with insecticidal soap or neem oil if you notice an infestation. Purslane is also resistant to most diseases, but proper plant spacing and good air circulation can help prevent potential issues.
Wild vs. Cultivated Purslane
Wild purslane grows in many parts of the world, often in disturbed soils, such as along roadsides or in abandoned lots. While wild purslane is edible and nutritious, cultivated varieties, like golden purslane, often have a milder flavor and larger leaves, making them more suitable for culinary use.
Common purslane contains oxalates, which can be problematic for individuals with kidney disorders or a history of kidney stones. Consuming high amounts of oxalates can lead to the formation of kidney stones or exacerbate existing conditions.
If you have a history of kidney issues, consult your healthcare provider before incorporating purslane into your diet.
Is common purslane safe to eat?
Yes, common purslane is safe to eat and is a nutritious addition to your diet. However, individuals with kidney issues or a history of kidney stones should consult their healthcare provider before consuming purslane due to its oxalate content.
Can I grow common purslane indoors?
Yes, you can grow common purslane indoors in containers with well-draining soil and adequate sunlight. Place the container near a sunny window or under grow lights to provide the necessary light.
How do I store harvested purslane?
To store fresh purslane, wrap it in a damp paper towel and place it in a sealed plastic bag or container. Store it in the refrigerator, where it should last for up to a week.
Can I use common purslane as a ground cover in my garden?
Common purslane makes an excellent ground cover due to its low-growing habit and dense foliage. It helps suppress weeds, conserve soil moisture, and prevent soil erosion.
How can I tell the difference between wild and cultivated purslane?
Wild purslane tends to have a more robust, tangy flavor and smaller leaves than cultivated varieties. Cultivated purslane, such as golden purslane, often has a milder flavor and larger leaves, making it more suitable for culinary use.
Wrapping Up Purslane
Common purslane is a versatile, nutritious, and easy-to-grow plant with many culinary and medicinal uses. Whether you grow it in your garden or forage for wild varieties, this often-overlooked “weed” can be a valuable addition to a healthy diet and a sustainable garden.
