Some help would be nice

any ideas as to if or when these guys could flower? i assume they are about 10-15 years old. (cephalocereus senelis)

Unless you can put that in the ground or a really big pot, I would not expect a flower. These are grown for their hairy spines, not the flowers. Not that the flowers aren't great, you just can't get flowers on small potted plants.

Apart from anything else, this is a high Andean plant and without a lot of high intensity sunlight it isn't likely to flower. When it is double that size and you can sit it outside at your cabin in the mountains ...

Desert Tropicals describes a cephalium as growing on plants from about 20' tall. Unfortunately they say this next to a picture of what is apparently a Cleistocactus strausii, so I don't know how accurate the information is

Cephalocereus senilis is from Mexico. It wants a hot, sunny place and few water and seems to be difficult to get flowers in cultivation...

Which one am I thinking of? Maybe Espostoa, that's from the Andes

[Buck Hemenway]

Right Ian. Probably Oreocereus as well.

Our friend Harvey Welton at Mexican Hat has told me that this plant will not flower until about 40 years old. There are very few plants of that age in the US and Mexico has severley restricted the transport of seed, so there are just a few growers actually growing it outside of Mexico.
