A "butterfly garden sprinkler" is a type of rotating sprinkler designed to mimic the gentle rain pattern of a butterfly's wings, providing even water distribution across a garden area by spraying water in a wide, circular pattern, often with a larger coverage radius compared to standard sprinklers, making it suitable for both small gardens and larger agricultural fields. It usually features a butterfly-shaped design and is known for its water-efficient operation, allowing for precise control over irrigation while minimizing water waste.
