ID = Cistus Albidus 'Snowfire' ↔ Cistus Albidus 'Snow Fire' ⇢ Rock Rose.

Nice find -- though it'd be hard not to notice the showy blossoms =)

I don't agree, but it's not my call in the end.... The leaf structure doesn't support your final choice of species, IMO. Gum cistus has much larger, narrower leaves and the "eye spots" are much less pronounced on the flowers.

The things with fragrance gardens is that they tend to stock whatever is fragrant and showy... Fragrance is subjective, too. Some things they grow may be barely fragrant, others more fragrant at night vs day (or vice versa) and others may be fragrant only when something comes in contact with it.... Let's not forget the varied ability among people to pick up scents, too.... Very subjective.... Most Cistus species are noted as have fragrant blossoms, so that may be enough for to qualify for the garden maintainer. I can't tell you for sure, but I do know neither this specimen, nor the larger shrub you photographed, have the unmistakable foliage associate with Common Gum Cistus. It does match the foliage of C. album, though, which is smaller, more ovate, more rose-like. C. ladanifer's leaves often get confused with Peonies, hence the common misidentification with folks calling their flowers Peonies. Gum Cistus' red petal spots also tend to be smaller and lighter in color -- more toward the red end than burgundy.

But, in the end it's your call which ID you feel most confident in.
