Possibly: Cereus peruvianus - night blooming cereus - Peruvian Apple


The cactus at our old family house was planted about 50 years ago. It is maybe
10-12 feet tall. It blooms at night, most years, each bloom only lasting until about
noon the next day. If you catch the flowers early, just after dawn, they are about
tennis ball size, and exquisite. They have a strong scent at night, which fades away quickly.
