i'm a shoreline botanist and travel around a lot of coastlines. Therefore a lot of waves and sea come into my view. There's nothing more pleasing to me to see a storm roll in over the ocean. I observe the way the plants along the beach seem to brace themselves for the onslaught of the weather change. Mind you it is fractional but i'm convinced that the drop in temperature signals the inner signam stell into going into a transition. This brings along the change of color seen in some plants. 
At Cornwell there is a plant that has adapted to this change more dramatically than any other species i have encountered. I  saw  it in  surfing posters on the web a couple of weeks ago. It was in the background of a poster they had in island posters about Tahiti. Being a botanist i thought how can this be right. There is such a big climatic differences between the two countries. I did some research and found that William Bligh took a sample of it with him. The plant is called fiuesh. It was first used as a medicinal plant by early Europeans as a cure for consumption.
