park, garden, yard, farm
園 centers on an enclosed cultivated space: a park, garden, yard, or farm. All meanings share the idea of a bounded area where plants are grown or nature is arranged.
園 combines 囗 (enclosure) with 袁, which likely contributes the sound. The character originally referred to an enclosed garden or orchard.
The enclosure 囗 surrounds 袁, like a fence around a garden. Picture a walled park where trees and flowers grow inside a protected space.
For エン, imagine the garden as the end of a long path: end -> エン, and you arrive at a peaceful enclosed park.
