The Wonderful World of Weeds

Weeds are generally described as pesky, unwanted plants that seem to appear out of nowhere, spread like celebrity news, and destroy more popular plants in their wake. Weeds are fast growing nuisances that are very hard to get rid of. But seen in another light, perhaps weeds have some value. In that sense, one man’s weed is another man’s garden. This project explores some of the practical uses of weeds.

Problem:

How can we learn more about weeds and how they function in the natural world?
