As the weather gets colder, Carmen Fernholz of Minnesota enjoys looking out at his fields of Kernza. This wheatgrass is a perennial, which means it overwinters and comes back in spring.
“It’s so nice to see some green fields late into November and December and early again in March and April,” he says.
Kernza grows chest-high, with roots that can extend nearly 10 feet below ground. So over time, it helps build soil carbon, improve soil health, and reduce runoff.
