Purslane
Portulaca oleracea
Also known as: Purslane, Common Purslane, Pigweed, Verdolaga
'Portulaca' derives from the Latin 'portula' (little gate or door), thought to refer to the way the seed capsule opens like a small lid. 'Oleracea' means 'of the vegetable garden' – the same species designation shared with cabbage and basil. Purslane has been eaten for over 2,000 years across the Mediterranean, Middle East, India, and China. It is a low-growing, succulent annual weed found throughout Australia in gardens, footpaths, disturbed coastal ground, and sandy soils. It thrives in full sun and hot, dry conditions, sprawling outward in a mat of fleshy, paddle-shaped leaves and reddish-pink stems. It is one of the most nutritionally remarkable weeds on the planet – and one of the most underrated. In many cultures, particularly in Turkey, Greece, and Mexico, it is actively cultivated and sold in markets.
When to Forage
Spring through autumn (October–April in southern Australia); most vigorous in summer heat.
Cautions
Very safe. Contains oxalic acid in moderate amounts – not a concern in culinary quantities, but those with kidney stones should be mindful. Avoid sites treated with herbicide. The high omega-3 content makes it particularly beneficial.
Nutrition
Exceptional source of omega-3 fatty acids (ALA) – one of the richest plant sources known. Also very high in vitamins A, C, and E; magnesium, potassium, calcium, and iron; and glutathione (antioxidant). Contains melatonin. Slightly mucilaginous texture when cooked, which is gut-soothing. A true superfood hiding in plain sight.
How to Identify
- Low-growing, mat-forming annual with thick, succulent, paddle- to teardrop-shaped leaves, smooth and glossy on both sides; bright green above, sometimes reddish beneath.
- Stems are smooth, round, fleshy, and characteristically reddish to pink or purple.
- Tiny yellow flowers with five petals, opening only in full sun in the morning. Easily missed.
- Seed capsule opens like a small lid (as the name implies), releasing many tiny black seeds.
- Entirely hairless. Succulent and juicy when broken – the stem snaps cleanly and exudes moisture.
Lookalikes
Some spurges grow in similar disturbed ground habitats. Distinguished immediately by the milky-white sap that oozes when any part is broken. Purslane has no latex. Always check the stem – spurge is toxic.
A related species with hairy leaf axils and pink-magenta flowers. Also edible, though less commonly used. The presence of hair at the leaf axils distinguishes it from P. oleracea.
How to Forage
Pick stems and leaves by hand from the ground – the plant is very easy to gather in quantity. Choose fresh, bright green growth; avoid yellowed or wilted specimens. Rinse well (purslane hugs the ground and can carry soil and grit). Best eaten within a day or two of picking. Stems and leaves are both eaten. Eat raw in salads for maximum omega-3 content, or cook briefly – it becomes pleasantly mucilaginous.
Recipe — Purslane, Tomato & Za'atar Fattoush
Ingredients: 3 large handfuls purslane leaves and tender stems; 2 ripe tomatoes, roughly chopped; 1 Lebanese cucumber, diced; 1/2 red onion, thinly sliced; 1 piece stale flatbread or pita, torn and toasted; 2 tbsp extra-virgin olive oil; 1 tbsp lemon juice; 1 tsp za'atar; salt and pepper. Method: Wash purslane thoroughly and spin dry. Tear larger stems into bite-sized pieces. Combine purslane, tomato, cucumber, and red onion in a large bowl. Whisk olive oil, lemon juice, za'atar, salt, and pepper. Add toasted bread pieces and pour dressing over. Toss gently. Serve immediately – the bread softens quickly in the dressing. Inspo: purslane in green smoothies – blend with cucumber, lemon, and mint; or purslane pickle – quick-brine in white wine vinegar with garlic and peppercorns.
