This little bush has a nice form, and it's blossoms are lovely for the first couple days. After that, though the bloom holds its form, it fades to a dull off-white, with dark brown stamens. Maybe this will change as it ages; it's only a year old.
Also, this plant is susceptible to rust, though not badly enough for it to drop its leaves. I think it wants less scorching sun in the summer, so I've moved it to a slightly shadier spot.
