Often considered a weed, discussions in gardening circles about the herb purslane usually revolve around methods for its eradication. We think this is a crying shame! Purslane’s succulent-like leaves are not only nutritious, they’re also tasty, with a flavor similar to spinach with a slight lemony tang. Because of its flavor profile, this herb is commonly used in Mediterranean, Asian, and Middle Eastern cuisines. Its weed-like attributes, such as requiring little attention and thriving in harsh climates with only two-month growing seasons, actually makes this plant a great one for beginner gardeners. If you do decide to invite this herb into your garden, keep a diligent eye on its flower development: if it’s allowed to seed, it’ll very likely bully its way into other sections of your herbaceous ‘hood.
Golden purslane is similar to the Garden varietal of this plant as it’s also been domesticated and grows in a more upright fashion rather than close to the ground like wild varieties. It has leaves even more tender than those of the Garden purslane and possess a lovely golden hue that makes them as pretty as they are tasty. Try tossing some on a salad or in a sandwich for a refreshing and nutritious change of pace from conventional lettuce.
