I saw several new-to-me flowering plants on the edge of the meadow on the west side below the Native Plant Area yesterday. Among them is this rock rose. I saw another rock rose earlier, on April 3 to be exact, behind a bench on the north side of the perimeter path, but that one has now finished blooming. This one is coming in a bit later. It has different flowers and leaves than the one on the north side. This one is very probably a Pink Rock Rose, Cistus incanus. Chances are that this one, like the one on the north side of the park, was planted by a human. Thank you, human, whoever you are.
