Most gardeners and farmers attack purslane when it infiltrates their domain. This is a shame.

The sprawling semi-succulent annual boasts the highest-yet-measured levels of omega-3 fatty acids in a plant. In my vegetable garden I transplant opportunistic purslane volunteers into tidy rows. I also grow ‘Golden’ purslane from seed. I know. Nuts.

Native Americans knew about purslane and used it fresh and cooked. On the other side of the Atlantic, Romans devoured it, BCE. It remains a well-known vegetable around the Mediterranean. And other North Americans are well informed: verdolagas (Spanish for “purslane”) are appreciated in Mexico, and routinely eaten.

The common purslane we know as a weed has uncertain origins. Asia? North Africa? And while it is thought to be a post-Columbian immigrant to North America, archaeological records have shown evidence of purslane seeds and pollen here as far back as 750 CE.

In the 1840s Henry David Thoreau was feasting on it in his Walden Pond cabin in Concord, Massachusetts. “I have made a satisfactory dinner, satisfactory on several accounts, simply off a dish of purslane (Portulaca oleracea) which I gathered in my cornfield, boiled and salted. I give the Latin on account of the savoriness of the trivial name,” he wrote in Walden, published in 1854. What does “satisfactory on several accounts” mean? For a man who wrote a lot, he does not elaborate.

There are many ways purslane can be enjoyed, cooked, but boiling it is not on my list. Generally speaking, it is at its most appealing raw, with a crisp texture and faint sourness. These attributes work well with softer ingredients like ripe peaches, creamy mozzarella, and even roasted bone marrow (as a relish purslane assuages guilt and cuts the fat). Processed until smooth it lends a fullness to raw soups and green sauces. It is an edible tonic.

As with some other vegetables (Japanese knotweed, sheep sorrel), purslane’s vivid color fades with heat, and it also turns slightly mucilaginous. In Cape Town, porseleinbredie was a traditional Cape Malay dish, a slow stew made with lamb and succulent purslane leaves. And C. Louis Leipoldt, a lauded South African poet and food writer (before there was such a thing), as well as a medical doctor and amateur botanist, liked his porseleinblaar stewed with butter and mace and pounded to a paste.

I think the Romans would relate.

How to Collect and Prepare Purslane

You can pick purslane leaves the minute they are recognizable, as seedlings. On more mature plants the stems can also be eaten as long as they are tender (older stems are fibrous). If you can pinch the stem off between forefinger and thumbnail, it is tender enough to eat. The fat, unripe seed capsules are pleasantly succulent morsels. If you do not want purslane to spread, pick those before they release their seeds.

Purslane’s flavor can be variable, as I learned from wild foods author John Slattery, author of Southwest Foraging: “If you gather it in the morning it will have more malic acid, and therefore be tangy in taste,” he writes. “Gathered in the afternoon it will be sweeter . . . as the malic acid is transformed into glucose.” I like it tangy.

Increasingly, purslane is showing up at farmers markets in late summer. When my own crop becomes too leggy, that is where I find a fresh supply. It has often wilted by the time it is sold and I plunge it into a large bowl of cool water until it has revived, snacking on the leaf tips while I wait.
