I have a Fairy Castle cactus 'Cereus tetragonus' and I was wondering how to get it to flower, or if anyone knew what the flowers look like. I"m just curious to see what it looks like in bloom.

Here is a photo of it... still quite small though.

In the wild this plant will get 6 1/2 to 27 feet tall and have large white flowers. Most cacti that get this tall don't flower until they are 3-5 feet high. If you want something smaller that might bloom more readilly, try this site. It's my favorite cactus/succulent store and has wonderful pictures!
