Research and Conservation in Southern Sonora, Mexico

Cochlospermum vitifolium (palo barril, rosa amarilla)

Palo barril has a straight white trunk up to 60 feet tall, unbranched all the way to the crown. The large flowers usually
appear in March when the tree is leafless, but flowering is occasionally as late as May. Ranges from Sonora south to
Bolivia, Brazil, and the West Indies. Widespread in cultivation because of its beauty and ease of propagation from cuttings.
There is a double-flowered cultivar.
