You know all about the health benefits from Omega-3 fatty acids, right? Well, you may be surprised to learn that a weed common in lawns and gardens is high in Omega-3 fatty acid: purslane. 
Purslane is not only nutritious -- it's actually quite palatable, too!
Yet people spend money on herbicides to get rid of this purslane, then go out and spend more money on Omega-3 capsules. Is it just me, or is there something wrong with this picture?
By the way, while purslane has no ornamental value, it is related to an ornamental plant: the succulent little annual known as "portulaca." The latter offers and array of flower colors, but also another feature that may be of even greater significance for those interested in low-maintenance landscaping: it is extremely drought-tolerant and even thrives in poor soils.
