I love Rose flower 
Roses are very pretty. I know they can come in a variety of colors.
Yes ! R.F vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds.
Yeah, I have never had a rose bush before, but I bet they are hard to take care of.
Interestingly,have acquired cultural significance in many societies.
I'm sure they are used in plenty of occasions and the Rose Parade as well.
Rose Parade, also known as the Tournament of Roses Parade, is part of "America's New Year Celebration" held in Pasadena, California each year 
That must be a sight to see. I bet it is wonderful.
