The NYBG has an annual orchid show, I've been several times and sat through a few fascinating talks about orchids. One of the things the docent said about orchids is that they are spread out world wide despite requiring exactingly specific conditions in which to germinate. As such, each orchid produces about a hijillion seeds (think about vanilla bean pods and all those tiny flecks. Those are seeds)

The docent said something like, if 1% of orchid seeds germinated the earth would be buried in orchids 100 feet deep. Something crazy like that. My depth may be off, but whatever it was, I remember it was way above our heads.
