Space-themed gardens are designed to reflect the beauty and mystery of outer space. They often feature plants and decorations that resemble celestial bodies, such as stars, planets, and galaxies. Common elements include dark-colored flowers, silver foliage, and structures that mimic spacecraft or rocket shapes. These gardens can also incorporate educational aspects, showcasing plants named after celestial objects or using layouts that represent constellations. Some may include features like solar panels or moon gardens that bloom at night, enhancing the connection to the cosmos while promoting sustainability and environmental awareness.
