Buddleja, commonly known as butterfly bush, is a genus of flowering plants in the family Scrophulariaceae. These shrubs are native to Asia, Africa, and the Americas, and are well-known for their long, fragrant flower spikes that attract butterflies and other pollinators. They typically bloom from summer to fall and come in various colors, including purple, pink, and white. Buddleja species are often used in gardens and landscapes for their ornamental value and ability to thrive in poor soil conditions. They prefer full sun and can grow rapidly, making them a popular choice for attracting wildlife. However, some species can become invasive in certain regions.
