Anyone who lives in a major city, where pollen-thick summer air seems incompatible with the dearth of trees, it can be easy to forget the fact that plants make the world go round. Here to remind you is a playlist of 10 TED Talks on the majesty and awesomeness of plants. Hear from not one but two rebel gardeners, as well as vegetarians, designers and conservationists.

TED playlists are collections of talks around a topic, built to illuminate ideas in context. A new playlist is added every week. We hope you enjoy this installment.

What is DNA barcoding, you ask? It’s a far more precise way of identifying plant species. In this video, Ellen Jorgensen — who gave today’s TED Talk “Biohacking, you can do it too”  – heads to a remote region of Alaska to collect the fragile plants found there and bring them back to her DIY biotech lab for a crowd-sourced science project.

This video was created by TED’s own Kari Mulholland. Stay tuned to the TED Blog for more videos of cool projects happening at Genspace.
