A lovely plant - try gently stroking the stamens of an open flower and see what happens

The stames slowly move downwards towards the petals - it might be a mechanism to encourage cross pollination - this works for some cultivated varieties - head to you local garden centre!!

Managed to find reference

Common rockrose’s inflorescence has only one flower open at a time and is quite short-lived. The plant only opens its flowers in fine weather and always directs them away from the sun. The flower doesn’t secrete nectar but is rather visited by pollen-gathering insects. Its stamens are sensitive to movement and react to dampness. As the pollinating insect brushes the anther the stamens drop pollen onto its fur and start to turn to the side, and this inflection makes it easier for the pistil in the middle of the flower to touch the next insect guest, and thus enhance its chances of receiving pollen from a neighbouring flower on its stigma.
