Notes
from the site:
Healthy seeds brought to the Seed Quarantine Room are separated from other plant material, then cleaned and analyzed for moisture content, weighed, and counted. A fume hood ensures that any contaminants are sequestered and filtered out. All but about 25 seeds (which are sent to the Reproductive Biology Laboratory) are slowly dried to 15 percent humidity, carefully labeled and packaged in heat-sealed foil containers, and—finally—stored in the Dixon National Tallgrass Prairie Seed Bank at -20 degrees Celsius. The Chicago Botanic Garden has committed to collecting 30 million seeds from 1,500 native species across the Midwest.
