FROST BEADS

I saw this frosted grass and noticed a little bead of ice at the tip of many of the grass blades

At first I thought it was just frozen dew, but why the big bead at the tip of the blade?

Perhaps it was a drop of water exuded by the plant in the night, before the temperature dropped.  When ground conditions are very wet, sometimes the roots suck in more than the plant can hold and root pressure causes a droplet to form at the tip of the leaf blade.  This is called guttation.

 Intriguing and beautiful.
