Finally got my snake plant to flower after three years of neglect—turns out mine needed to be genuinely ignored, not just underwatered

Finally got my snake plant to flower after three years of neglect—turns out mine needed to be genuinely ignored, not just underwatered. The smell is weirdly pleasant, almost vanilla-like. I'm curious though: does anyone else's flower once established, or was mine just deciding to finally reward my laziness? I've heard conflicting things about what actually triggers it.
