There are more than 150 species of roses and thousands of named varieties within these species. Most rose varieties are deciduous shrubs, but other growth habits such climbers, which need a means of support, exist. Rose flowers originally possessed five petals, but breeders have developed varieties that produce flowers with more than 40 petals. Sharp extensions along stems are often mistakenly called thorns, they are actually prickles. In addition to their ornamental value, roses can also be used in medicine, food, and perfume.
It is often difficult to place a specific rose variety into a single category. ‘Harlekin’ is a climbing rose. Flowers have up to 40 petals. Petal color is cream with pink edges.
