Chorisia speciosa, commonly known as the Silk Floss Tree, is a deciduous tree native to South America, particularly Brazil and Argentina. It is renowned for its spectacular display of large, showy pink to purple flowers that bloom in late summer to fall, often when the branches are nearly leafless. The tree’s thick, bottle-shaped trunk is covered in sharp conical spines, serving both as a defense mechanism and as a water reservoir during dry periods. Its palmate, bright green leaves provide lush foliage in the growing season, and its woody seed pods release silky white fibers that resemble floss, giving the tree its common name. Chorisia speciosa thrives in warm, sunny climates with well-drained soil and is valued as a dramatic ornamental tree in parks, gardens, and streetscapes, admired for its exotic beauty and architectural form.
