The flower renowned for its ability to attract butterflies is the butterfly bush (Buddleja). This vibrant plant produces clusters of fragrant flowers in various colors, such as purple, pink, and white. Its nectar-rich blossoms are particularly appealing to butterflies, drawing them in during the warmer months. Other plants, like milkweed and coneflower, also attract butterflies; however, the butterfly bush is specifically celebrated for its high nectar content and capacity to attract a wide variety of butterfly species. By planting butterfly bushes in gardens, enthusiasts can create inviting habitats that support butterfly populations and contribute to biodiversity.
