Purslane: The Edible ‘Weed’ Worth Keeping
If you've ever weeded a garden bed or a crack in the pavement in summer, you've probably met purslane — a low, sprawling plant with smooth reddish…
I spent a whole summer yanking purslane out of the cracks in my patio before I found out I’d been composting a vegetable. It’s the low, sprawling stuff with smooth reddish stems and small, plump leaves that shows up uninvited in garden beds everywhere. Across the Mediterranean, the Middle East, Mexico, and much of Asia, though, purslane (Portulaca oleracea) has been eaten on purpose for centuries, and it’s genuinely worth eating.

A ‘weed’ with a place at the table
Purslane grows almost anywhere and spreads fast, which is exactly why gardeners fight it. The leaves and tender stems are good eating, though: mildly tangy, a little lemony, with a juicy, slightly salty crunch. It goes into salads, gets folded into soups and stews, stirred into yogurt, or sautéed quickly as a simple green.
What makes it worth eating
Purslane’s real claim to fame is that it’s one of the richest plant sources of omega-3 fatty acids, specifically ALA (alpha-linolenic acid), which is unusual for a leafy green. Most greens don’t come close. It also brings vitamins A and C, minerals like magnesium and potassium, plus antioxidants, all for almost no calories. Think of it as a good vegetable to fold into a varied diet, not a supplement, and not a substitute for one.
How to tell it apart from the dangerous look-alike
Purslane has thick, smooth, fleshy leaves, hairless reddish stems, and small yellow flowers. The one to actually worry about is spurge, which isn’t edible and can irritate your skin and mouth. Snap a stem to check: spurge leaks a milky white sap and has thin, wiry stems with slimmer leaves, while purslane has no sap at all and noticeably thicker, succulent stems. If you’re not sure, don’t eat it, and only forage from ground you know hasn’t been sprayed.
Who should ease up on it
Purslane runs fairly high in oxalates. That’s a non-issue for most people eating it as part of a balanced diet, but if you’re prone to calcium-oxalate kidney stones, eat it in moderation. A quick cook reduces the oxalate content somewhat, which is probably why so many traditional recipes cook it rather than serve it raw.
‘Weed’ turns out to be a label, not a fact. Learn to tell purslane apart from its look-alikes, pick it from clean ground, and it earns a spot in your salad bowl instead of your compost bin.
