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
The Rose Parade, hosted by the Pasadena Tournament of Roses, is an annual parade held mostly along Colorado Boulevard in Pasadena, California, on New Year's Day (or on Monday, January 2 if New Year's Day falls on a Sunday). Usually beginning in the morning at 8:00 a.m. Pacific Time (), it is produced by the non-profit Pasadena Tournament of Roses Association and includes flower-covered floats, marching bands, and equestrian units. The parade is followed in the afternoon

They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp prickles. Flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe
