How many petals does a rose have?
The wild type of plant all roses are bred from has 5 petals (rarely 4). There can be a doubling of this number and other factors that increase the number of petals in the domestic roses. In garden pants roses with only 5 petals are called single. A rose with 4-8 petals is classed as a single when showing roses. http://www.marinrose.org/singleroses.htm… http://www.botanical-online.com/familiar… http://www.rogersroses.com/gallery/defau… Double roses are grouped: 9-16 are semi-double and 17-25 are double. Full roses have 26 – 40 petals. After 40 the terminology gets vague. Cabbage roses can have ~100 petals. http://www.ars.org/Judges/petal-count.ht…
