They're usually popular as landscaping plants, and are quite common, despite their containing appreciable amounts of mind-altering chemicals (but that's not important right now).[b said:Quote[/b] (LLeopardGGecko @ Jan. 18 2006,9:08)]So is Trichocereus spp easy to find in stores? Do you think I'd be able to find it at Home Depot?
I'd try Home Depot, and if that proves fruitless, there are countless mail-order suppliers that actually sell them as stock plants for dirt cheap. The one I'd recommend most is T. pachanoi as it's easy to work with, very vigorous and can be found for sale anywhere online (eBay, for example).
Good luck!
