Botanists have discovered that Corydalis conorhiza grows a never-before described network of roots that reach upwards into the overlying snowpack to grab nutrients. This makes the plant the first species known to forage for nutrients in the snow.
[...]
The team reasoned that the unusual roots must be used to gather nitrogen that is trapped in snow flakes as they form. To test the hypothesis they added a traceable isotope of nitrogen in water to snow above C. conorhiza plants. After a few days, the team found that parts of the plant were rich in the isotope.
