This is the same picture as yesterday, but after a rain. During a dry period the little fern plants shrivel up and aren't noticeable. After a rain the resurrection fern opens and like magic our oaks are covered in fern. These are small plants, the mature fern can cover the entire trunk. This fern is seldom seen growing on anything other then oak. But in my yard it is on many things, including a rose and an orchid pot.
