Those isolated green patches under the trees would appear to be strong hints that Tufted Poppies are creatures of the sun. In fact, the flowers are so sun-oriented that they close up altogether when it's overcast. I'm not certain why - is there a favored pollinator that only turns up when the sun's out? Or do the poppies just prefer daytime pollinators but their daylight detectors are a bit tightly wound? If you're a phenologist, or possibly a poppy yourself, feel free to write in and explain.
The patches of white are likely a variety of popcorn flower.
