I purchased this Hatiora cylindrica because I thought it looked cool as hell (like a lot of cacti, IMO), but after doing a little researching for care info I actually found out it's an endangered species. As a biologist for my professional career, this got me really excited. I thought I would see what other endangered/threatened plants anyone else had, to get some ideas for new additions. Obligatory picture of the lil' guy I grew from a 2-inch seedling.
