Calotropis gigantea, commonly known as the crown flower, is a large shrub or small tree that is deciduous in cooler climates and evergreen where temperatures remain high year-round. It is native to dry, tropical regions such as open woodlands and scrublands across South and Southeast Asia, including Cambodia, Vietnam, Bangladesh, Indonesia, Malaysia, Thailand, Sri Lanka, India, China, Pakistan, and Nepal. The plant typically grows up to 13 feet tall and wide, with a stout, upright form. It features clusters of waxy flowers, which are most commonly white or lavender, with a small, crown-like structure rising from the center, giving the plant its common name. The flowers are showy and often used in floral arrangements and religious offerings. The blooming season extends throughout the year in warmer climates.

The crown flower is valued for its ornamental flowers and is used in traditional medicine and for producing fibers. It is drought-tolerant and thrives in full sun with well-drained soil, making it suitable for xeriscaping and as an accent plant in dry gardens. However, it is potentially invasive in some regions outside its native range due to its ability to spread rapidly and outcompete native flora. Gardeners should check local regulations before planting. Calotropis gigantea contains compounds that are toxic if ingested and can cause skin irritation, so caution is advised when handling the plant.CC BY-SA 4.0
