Saguaro in April: what the park service says
Late April is when saguaros start flowering. The park service says the tops of the trunks and arms sprout large, creamy white flowers from late April through early June; each opens at night and closes the next afternoon, and is pollinated by nectar-feeding bats, birds and insects. A saguaro has to be about 35 years old before it flowers at all.
