1. • Do not have thorns

     • Contrary to pop culture references, roses do not have thorns, which are the sharp woody points of certain shrubs and trees, including honey locusts and citrus trees. The flowers instead have prickles that form from the skin of the plant, similar to how hair grows.

   Do roses have prickles?

   • They have existed since the emergence of ferns and related species, some of which had prickles on their stems, at least 400 million years ago, according to The New York Times. They have now undergone 28 separate evolutionary cycles. Some roses have prickles on their stems, while other plants have them on their leaves or fruits.

   Are prickles on roses a common ancestor?

   • Prickles on roses and other plants evolved independently at least 28 times over 400 million years, according to the study. While this means the thorny mechanism cannot be traced to a common ancestor, understanding the genetic origin of the trait could help horticulturists cultivate thornless varieties of plants in the future.

   Is there a rose without thorns?

   • There is no rose without thorns, the old saying goes. But to botanists, there is no rose with thorns: The spiky outgrowths of a rose stem are called “prickles,” and are biologically distinct from the stiff, woody thorns of other plants. Prickles are a remarkable example of evolution repeating itself.

   Are there roses without spikes?

   • About 400 of them are commonly known as “spiny solanum.” There are rose species without spikes today because, prior to this discovery, one way to get rid of prickles from plants was to try to crossbreed the plant with a variant that had naturally lost its prickles.

   Aug 2, 2024 · Roses, nightshades, eggplants, and even certain rice crops have a mutual, rather prickly feature – they sport protrusions, technically known as prickles. These prickles have been intriguing researchers and even hopeless romantics for ages due to their ubiquity across vastly different plant species.

   Apr 25, 2024 · Roses have thorns or prickles to protect themselves from wildlife creatures that feed on them. They also protect them from humans who want to pick the flowers, interrupting their life cycle. Thorns keep intruders away, so the flower can get fertilized, produce seeds, and help the plant reproduce.
