Plants don't need to be specifically by cold or warm places, but they need to be in a place with conditions that are suitable for their specific species.

Here's why:

* Temperature: Different plants have different temperature preferences. Some thrive in cold climates (like cacti and succulents), while others need warmer temperatures (like tropical plants).

* Sunlight: Plants need sunlight to photosynthesize, but the amount they need varies. Some plants tolerate shade, while others need full sun.

* Water: Some plants need lots of water, while others are drought-tolerant.

* Soil: Different plants require different types of soil with specific nutrients and drainage properties.

So, the location of a plant doesn't have to be specifically cold or warm, but the environment must meet its specific needs. This is why it's important to choose plants that are well-suited to your local climate and growing conditions.
