Lovely video mate as I adore roses and it's similar to my "lighter shade of pale" on the back garden as that carries 24 petals and is still going strong now besides "Birthday Girl" on the front garden.
Yes but the main centre is always white but when they explode sometimes in a large display they look glorious.
Red roses are even beautiful when they are in full bloom. http://www.pinterest.com/pin/446419381809154167
