Your Mother's a Horticulturist

I saw one of these today. I don't know what it is for sure, but I think it's full of alien death-spores. If any of you horticulturist or SETI types know what we're looking at here, drop me a line.

I'll bet all of this botany talk makes you wonder what would happen if Weezer covered Radiohead. Funny thing about that. What happens is they nail it. Hard.
