How do roses reproduce in the wild?

Yaargh, ya need ta get em all thorny.

Roses produce seed. What we call “rose hips”, the round bulb left when the flower’s petals fall, will hold the rose seeds when they mature in the Fall.

In the case of domestic roses, the only folks who try to grow from seed are hybridizers who are developing new varieties. If you try to grow a rose from the seed of one of your garden roses, the offspring rarely look like the parent, and are often not very attractive. That’s why cuttings are typically used; they always produce a plant exactly like the parent.

Left to reproduce from seed, the offspring of a hybrid rose will revert to something resembling a wild rose within a few generations.

Rose hips are full of viatmin c. Birds love them as food (how they spread). They also make great tea.
