A moon garden, also known as a twilight garden, evening garden, night garden, moonlight garden, or dream garden, is a type of garden designed to be enjoyed at dusk and nighttime. Fragrant flowers, light-colored vegetation or blooms that are visible by moonlight, blossoms that open at night instead of day, and plants which attract night pollinators you can hear, are all elements of a moon garden. The different effects produced by moonlight compared to sunlight in human color perception emphasize the colors of certain flowers more than others, bringing out different tones which are not available during daytime or with artificial lights. Night-blooming plants are typically moth, bat or wind pollinated. Planning an evening garden can perform double-duty as a setting for evening entertaining such as barbecues and parties.
