yeah nice flower, its rare to have them flower in cultivation. at least with the regular type. i have personally only seen flowers in books, on the forum and maybe once at a tropical fish store with a huge overgrown, old snake plant.
i've tried these plants had one for a few years my staff hiddei( she no longer works with us) gave me one, it grew and thrived while my other plants died. the cold fall rain killed it. i tried it again but the pot was ill equipped to handle it, it kept falling out,spilling dirt everywhere in my room and over and i threw it out in digust.
recently i have gotten back into houseplants and am doing better i think maturity and obsession with all things green have allot to do with it.
