Cephalocereus senilis

Old Man Cactus from high altitude in the Andes. Slow growing.

4.Indoors OK, Outdoors OK only if protected from winter rain.

Removing the top metre when we had to demolish the big greenhouses.

You need quite a big plant to get flowers, or else a cutting from a big plant.

Flowers just starting to open as the sun goes down.

Fully open by the light of the silvery moon.
