Cratoxylum formosum is a tropical tree from Southeast Asia, grown mainly for timber and the ornamental pink or white flowers, and rarely cultivated as a garden plant. Its key to growing is consistently moist, warm, humid conditions in full sun to light shade, since it naturally grows in swampy margins and wet forest.
