Trying to figure out what to do with that daylily in your front yard? Wonder what it’s good for? (It might be edible!) Check out http://www.pfaf.org/, where you’ll find an impressive database of over 7000 plants and their alternative uses for humankind. Their Top 20 Plants lists for edibility and medicinal value are a great resource when planning what you can plant in your garden that might help you out after grid crash.
According to the introduction to their companion book, 20 is also the magic number when it comes to our current diets: only 20 plants supply 90% of human food. Wow! I wish that they’d gone on to list those twenty foods, but perhaps it’s buried a little deeper in the text. This site is a great resource for someone who either wants to find out about a particular plant via their search function or someone looking to plan a landscape that does more than simply look nice.
