"Bermuda Spice" has stronger pink tones and larger, fuller blooms when the weather is cooler. By mid-Summer, blooms are smaller, a little less full, and more cream to white in color.
Here in central New Jersey, my 2-year-old own-root "Bermuda Spice" needs to be cut back a lot after Winter, but doesn't seem to mind. Last year, it reached about 4 feet tall and slightly wider, but this is its size at its first flush for 2015.
