What are the Rose Thorns?
Rose thorns are outgrowths of plant tissue on the top layer of the plant’s bark. So thorns are leaves or shoots transformed by evolution, while prickles are outgrowths of the epidermis (plant tissue of the upper bark layer). Some roses are famed in history for their thorns, as is reflected in their names (barbed wire, burdock, thorny rose). The thorns may be few, or, on the contrary, they cover the stem. The thorns are referred to as a rose variety and are distinguished by their shape and size. The specialists distinguish between the rose prickles:
- straight;
- arch-shaped;
- hook-shaped;
- triangular;
- bristle-shaped;
- spiky, etc.

Modern breeding has made it possible to grow rose varieties with soft and almost invisible thorns.

But many connoisseurs of these classic flowers cannot imagine a rose without prickles and find unique beauty and appeal in them.
Experienced plant breeders and florists use the maturity of the thorns to determine the state of the rose’s wood and to prune the plant correctly. Still, the rose is a most unusual and delicate flower, which romantic lovers will always admire. The symbol of love has kept feelings alive for many years.
How Does the Thorn of a Rose Protect the Flower?
The thorns usually act as protection but can also help to support the stem, protect a flower from the sun, and retain water. You can read about it in more detail below:
- The prickles can help roses to retain water. Whether it is raining or dew, every drop of water that falls on the spikes is directed to the plant’s body, where it will be absorbed through the pores. In this way, they can avoid dehydration even if they live in the desert with this system.
- In curly species, the thorns also serve as hooks to support the stem. The thorns are sharp formations that result from a change in the hairs of the surface. Older species, such as R. Spinosissima and R. Rugosa, are straight as daggers, while younger species are curved and hooked.
- The fact that the whole body of the plant is covered with thorns is a way of protecting the rose from the sun. Of course, this protection will be more excellent or less, depending on the characteristics of these spikes. If they are long and very numerous, surely the surface of the rose will not be as vulnerable to the sun as if there were only a few and if they were very short.
