Purslane (Portulaca oleracea) is a versatile plant recognized for its succulent leaves. It is an edible plant, suitable for container gardens. Growing purslane in pots allows gardeners to enjoy this unique plant in a controlled and accessible manner.
Why Grow Purslane in Pots
Cultivating purslane in containers offers several advantages for gardeners with limited space or those seeking more control. Containers manage the plant’s spreading nature, preventing it from taking over garden beds. Purslane naturally trails, making it an attractive “spiller” plant for hanging baskets or pot edges, adding visual interest to balconies or patios.
Potted purslane is portable, allowing it to be moved for optimal sun exposure or brought indoors during colder months. This flexibility ensures the plant receives its preferred warm, sunny conditions. Growing in containers also makes harvesting more convenient, as the plant is elevated and easily accessible.
Preparing for Potted Purslane
Containers must have drainage holes to prevent waterlogging. Terracotta pots are a good choice as they allow soil to dry more efficiently, which purslane prefers. A 12-inch container can accommodate multiple purslane plants.
Purslane thrives in well-draining conditions. A regular potting mix is suitable, and amending it with organic compost supports vigorous growth. A sandy or loamy mix is preferred to ensure proper drainage and avoid root rot. The soil pH should ideally be between 5.5 and 7.5.
Caring for Potted Purslane
Purslane requires ample sunlight, ideally at least six to eight hours of direct sun daily, to encourage flowering and succulent leaf development. If grown indoors, a south-facing window provides the necessary bright light. The plant thrives in warm temperatures, typically between 70–100°F (21–37°C), making it suitable for hot, sunny spots.
As a succulent, purslane stores water in its fleshy leaves and stems, making it drought-tolerant. Water only when the top inch of soil feels dry, avoiding overwatering to prevent root rot. A balanced, water-soluble fertilizer can be applied monthly during spring and summer, though little to no fertilization is needed if compost is initially incorporated.
Harvesting and Enjoying Potted Purslane
Harvesting purslane from pots encourages more foliage. Pinch off stems or cut them with scissors, leaving at least two inches of growth at the base for regeneration. Frequent harvesting manages the plant’s size and promotes bushier growth. Harvesting early in the day can result in a more tart, lemony flavor due to higher malic acid concentrations.
The leaves, stems, flower buds, and seeds of purslane are edible. It has a slightly tart, lemony, or peppery taste, sometimes described as reminiscent of spinach or watercress. Purslane is highly nutritious, containing omega-3 fatty acids, vitamins A and C, calcium, iron, magnesium, and potassium. This versatile plant can be enjoyed raw in salads, blended into smoothies, or cooked in stir-fries, soups, and omelets.
