Roses are a very adaptable plant, and can be found in a variety of ecosystems, but they are most commonly associated with:

* Temperate Deciduous Forests: This is their natural habitat, where they thrive in the cool, humid climates and rich soils.

* Gardens: This is where most cultivated roses are found, thanks to their beauty and popularity.

* Parks: Many parks feature rose gardens, adding a touch of elegance and fragrance.

* Urban Environments: Roses can also be found in urban areas, where they are planted in landscaping and along roadsides.

It's important to note that while roses are found in these environments, they are not native to all of them. Many rose species have been cultivated and introduced to new areas.
