'Lost crops' could have fed as many as maize

By Talia Ogliore
 
Make some room in the garden, you storied three sisters: the winter squash, climbing beans and the vegetable we know as corn. Grown together, newly examined "lost crops" could have produced enough seed to feed as many indigenous people as traditionally grown maize, according to new research from Washington University in St. Louis.
 
 
But there are no written or oral histories to describe them. The domesticated forms of the lost crops are thought to be extinct.
 
Writing in the Journal of Ethnobiology, Natalie Muellert, assistant professor of archaeology in Arts & Sciences, describes how she painstakingly grew and calculated yield estimates for two annual plants that were cultivated in eastern North America for thousands of years—and then abandoned.
 
Growing goosefoot (Chenopodium, sp.) and erect knotweed (Polygonum erectum) together is more productive than growing either one alone, Mueller discovered. Planted in tandem, along with the other known lost crops, they could have fed thousands.
 
Archaeologists found the first evidence of the lost crops in rock shelters in Kentucky and Arkansas in the 1930s. Seed caches and dried leaves were their only clues. Over the past 25 years, pioneering research by Gayle Fritz, professor emerita of archaeology at Washington University, helped to establish the fact that a previously unknown crop complex had supported local societies for millennia before maize—a.k.a. corn—was adopted as a staple crop.

Sunflowers at Gordon Skagit Farms

Video: Sunflowers at Gordon Skagit Farms

Last year we had the chance to tour the 8-acre sunflower field at Gordon Skagit Farms and today I thought it would be fun to share some of the footage we filmed with you. If you’re within driving distance of the Skagit Valley and are looking for something to do this weekend, Gordon Skagit is open through the end of the month. In addition to having more specialty squash, pumpkins, and gourds than you can imagine, you will also be able to see this amazing sunflower field in its full glory.
