We have a "second spring" in our area. The summers are very dry with hardly any rain. In the fall, when it begins to rain again, the mosses and ferns and lichens all green up and it seems like a second spring.
Some might call it the start of the rainy season but it feels like second spring to me. It started raining yesterday and everyone seems ready for the rain. It won't be long till everything greens up. I can't wait!
Update... It is early November and we are in our second spring now. We've had more than a bit of rain and the mosses and ferns are very green. At the same time, the deciduous trees and bushes are turning fall colors and losing their leaves.
