Among the huge assortment of roses, the most popular are plants called thornless. Flowers with this name are ideal for creating landscape and park areas. The article provides a description of some varieties of thornless roses, and also discusses the nuances of their choice.
Roses without thorns are distinguished by the complete or partial absence of thorns on the stems. The thorns of such plants, in contrast to the thorns of classic roses and rose hips, are softer and amenable to deformation. They are located in the lower part of the stem, and as they move towards the bud, they fade away or form single short (up to 1 mm) soft thorns.
This feature allows you to painlessly cut flowers and take care of plants.

- reduced resistance to precipitation;
- single flowering;
- increased risk of fungal diseases;
