Does anyone know why roses have flowers when they have no use for reproduction?

Roses does not have seeds. It grows from its stem.

Yes, roses have seeds. They are called rose hips. They are the large globular objects that form from the flower after it dies. Many people collect rose hips as a source of Vitamin C. Since most of the roses we are used to seeing are hybrids, its easy to forget that roses come from seeds.





I have grown miniature roses from hips. It's a challenging process because the hips must be kept under freezing for a certain period of time before they germinate. I put them in my freezer. People in cold climates can just harvest their rose bushes after the first snow.





Roses grown from hips have new genetic material from the parent bush and may or may not look the way you are expecting. For that reason, most hybrid roses are reproduced from cuttings. The daughter plant is then a clone of the parent and the flower it produces is identical to the parent.





Rose breeders highly control how their roses are germinated and harvest the hips hoping to get a new kind of rose when the new bush blooms.
Reply:Flowers are the reproductive organs of plants. And sorry but you are mistaken. A rose needs its flowers for reproduction.





"Rose species are usually sexual and have a regular meiosis"
