I think it must be something common to most of us. Out of the literally dozens of orchids I have had over the years, at least 2/3 never lived past a month after I bought them and only ONE every flowered after the initial one in it's tribute however, that one bloomed about once a month for several years (that species must not be very finicky about conditions) and had I not gotten negligent and let it dry out, I fully assume it would still be growing and flowering now.
actually that seems to be the story with a lot of the stuff. It's hard for me to get an Indoor plant up and running, but the ones that do often last a damn long time defined as "until I forget to water them for a few months) The downside of that of course, is that when that does happen, I can't just get another of the same species, it seems to be an individual to individual thing.
As it stands now, the oldest one is probably the "what is it" which is now going on two years and still flowering (for a weed it's seems unusually hardy) (you'd think by now I'd have gotten some clue as to what it is, I've really got to send a cutting to the ag station). Probably followed by the rose apple seedlings (which are mostly notable for being absolutely incredibly resistant to water stress, I've forgotten to water them for months at a time and they don't even notice (and no they aren't cacti or something else water storing)
