A massive archive of 150,000+ public-domain images—covering hundreds of years!—just went online. So, naturally, we scoured it to find the loveliest plant pictures we could.

It’s not every day that 150,000+ vintage illustrations of the natural world go online, free for all to download and use. But that’s just what happened last week when the Biodiversity Heritage Library uploaded an enormous collection to Flickr, with some images dating back hundreds of years. Naturally, we plunged right in to find the greatest, loveliest botanical illustrations and present them to you, ready to be printed and framed (or turned into tattoos).
