These plants are native to a broad range of environments, including Asia, Africa, and the Americas. The most commonly cultivated species, Buddleja davidii, is native to central China and Japan. This species has been introduced to many other parts of the world and has naturalized in some areas, even becoming invasive in certain regions due to its prolific seed production and ability to colonize disturbed areas.

Hardiness: Buddleja is typically hardy in USDA zones 5-9, making it suitable for a range of climates. It is a robust and hardy plant, capable of surviving harsh conditions, including urban pollution and poor, dry soils.
Flowers: The flowers are a significant feature of Buddleja, borne in dense, conical panicles at the ends of branches. They bloom from summer to fall and come in a variety of colors, including shades of purple, pink, white, and yellow, depending on the species. The blossoms are intensely fragrant, adding another layer of sensory appeal.
Uses: Buddleja has a variety of uses in landscaping and gardening. Its large size and showy flowers make it a fantastic specimen plant or focal point in a garden. It can also be used in borders or as a part of wildlife gardens, given its attraction to pollinators. Furthermore, smaller cultivars can be grown in containers for patio or balcony gardens.
Pollinators: Buddleja is most known for attracting butterflies, earning it its common name. The flowers are rich in nectar, making them irresistible to these and other pollinators, like bees and hummingbirds. This can enhance local biodiversity and contribute to a healthier ecosystem.
