It was not until finding this photo that I realized the petals were in the shape of true love, reminding me to admire the details if not stopping for the sweet smell roses...or in this case rockrose, and in my experience not scented. Generally, rockroses are unique natives from the Mediterranean, bearing showy flowers while seemingly disinterested in receiving any love. Have you heard of killing plants with kindness, well in this case, rockroses do not like to be fussed over, and especially not overwatered...much like our native Ceanothus that detests too much summer water.
Do not let the photo fool you. C. x skanbergii's flowers are only an inch across, which might be why I did not notice its delicate details. They are, however, prolific, covered in a pink drift starting in late spring into summer. They may rebloom but not as abundantly.
To be candid, I planted ours in the wrong place. At the time, the garden was rather open, but as I slowly filled in areas it started to compete with others, in part to avoid shade by contorting its reach elsewhere. A plant that reaches eight feet across needs room under normal circumstances; depriving rockroses of sun is not an option. Which reminds me, some references mention a common name, "dwarf pink rockrose," which I cannot imagine refers to plant size but probably the smaller flowers than others in the genus. I would still consider this plant for ground cover uses if its height is desirable, but there are truer dwarf species that also spread, such as Cistus x pulverulentus 'Sunset' or Cistus salviifolius 'Prostratus.'
