Last night it rained 2 inches.   In these pictures, you can see rain drops on the leaves of some hostas living in my Hosta Dell.

The next one is also featuring water droplets on hosta leaves, but the difference is this rain has been taken into the plant through its roots, and is now being exuded by the hosta from tiny pores at the edge of the leaves called stoma.   Usually the atmosphere is warm and dry enough that the water vapor being transpired just evaporates as fast as it forms.  But sometimes, when things are very wet so the plant has an excess of water, and it is cool and humid out, the vapor being emitted by the plant forms tiny droplets around the pores.

It’s very cool and grey out there right now, and quite wet as well.   The ground here is fairly saturated and slopes almost imperceptibly, and so the water that fell from the sky doesn’t really have anyplace to go.   Even so, I need to take Ruby for her walk.   So off I go.
