www.mistersmartyplants.com is the world’s first dedicated to crowd sourced plant identification. It was envisioned in an MIT Media Labs course and has been helping curious people ID plants and flowers since 2010.
Mister Smarty Plants collects unknown flower and plant photos from twitter or by direct upload of “mystery plants”, site members then work to identify the photos. After enough votes for a name are entered, the image poster is emailed or tweeted with the identification.
