I have a lot of purslane (wild) growing in my garden. I know some can be poision. How would I tell the difference? Is there a site that could help with this? Thanks
If it's Portulaca oleracea that you refer to as your "wild" purslane it is completely edible. Google "purslane" and read away about the benefits of including this plant in your diet..
References to its poisonous properties appear for livestock, especially those that are starved and are fed large amounts of this herb. It does contain oxalates and nitrates and appears that the No. American plants are lower in these substances as compared to it in other parts of the world (Australia for example). Remember too that potatoes and tomatoes as well as spinich (which also contain oxalates) also contain toxic substances and we eat those on regular basis.
