Buddleja asiatica, commonly known as Asian Butterfly Bush, is a deciduous shrub native to a variety of habitats including forest margins, open woodlands, and scrub areas in South and Southeast Asia. This includes countries such as India, Nepal, Bangladesh, China, Taiwan, Myanmar (Burma), Thailand, Laos, Cambodia, Vietnam, Malaysia, New Guinea, and the Philippines. It typically grows to a height of 3-5 meters with a similar spread. The plant features lance-shaped leaves and clusters of small, fragrant, white to pale lilac flowers that bloom in late winter to early spring, providing an early source of nectar for butterflies and other pollinators.

Asian Butterfly Bush is valued for its fragrant flowers and ability to attract wildlife. It is often used in ornamental plantings, as a specimen shrub, or for naturalizing in informal garden settings. It thrives in full sun to partial shade and prefers well-drained soil, though it is tolerant of a range of soil conditions. Regular pruning is recommended to maintain a compact form and to encourage prolific flowering. Gardeners should be aware that Buddleja asiatica can become invasive outside its native range due to its prolific seed production and should check local regulations before planting.CC BY-SA 4.0
