Winters in eastern Russia are intensely cold, with air temperatures regularly reaching -30 degrees Fahrenheit in some locations. It is a seemingly inhospitable climate, but native plants have found ways to thrive there.

To find out, the modern-day botanical explorer set off across eastern Russia to collect specimens of the perennial grass Miscanthus sacchariflorus.
