I have a slight dichotomy issue, i hope the members of this forum can help me. Recently, I speared myself upon several small cacti lost in field of extremely tall grass. After the initial shock of such a deviously laid trap i took a closer look at them. I believe they are Echinopsis Peruviana, Peruvian torch cactus. The only thing that doesn't match up between the appearance of the two cacti is the spines. Pictures I've viewed of these cacti show the spines decreasing in length toward the top. The cacti i found on the other hand seem to have their largest spines at the top (although the are a very similar length to those on the bottom) with the largest reaching 3-1/4 inches. What i would like to know is if being kept in a place with very little light could possibly cause the cacti to stunt in this manner and allow the spines to reach this size at the top of the plant and if they're even still alive. Additionally I would be grateful for any information pertaining to potting or planting them and keeping them alive, I'm not very good with plants so I feel that maybe a cactus would be a good garden option. Thank you very much! -The Cactus Wrestler
What country were you in when you stumbled upon this cactus? Assuming you were in California, the simplest answer would be that you've misidentified it, given that the cactus you mention is native to Peru.
very true but the owner of the property i found them on believed them to be San Pedro cacti. They look nothing like San Pedros however and strongly resemble Peruvian Torch Cacti. Also the focus of my question was meant to be the effects of a low light habitat on spine formation, i'm sorry if that was confusing.
