The rose family is a medium-sized family of flowering plants. The rose family (Rosaceae) is one of the major angiosperm families. The leaves are generally arranged spirally. Flowers of plants in the rose family are generally described as "showy". They are actinomorphic and almost always hermaphroditic. Rosaceae generally have five sepals, and five petals.
